A History of Fender Bass Modeling Amps

Just a little general background for those who might be interested. Or, if you are fortunate enough to have hands-on experience in this area, please feel free to chime in!

Fender B-DEC 30 - 2006-2011 - 1st Generation
(Not a Rumble)
The Bass Digital Entertainment Center is so much more than just a 30-watt amp with 10" speaker and different voices! The kickback cab contains goodies designed to help teach bass guitar with built-in drum tracks, loops, and MIDI facilities for other instruments as well, for you to play along with your own virtual band, and an extra instrument input for your live instructor, band mate, or friend. With detailed control of the tracks, tempos (even speedup!) and loops, you're never at a loss for entertaining musical lessons. Software updates are through the MIDI interface. A 1/4" line level output affords recording or sound reinforcement. The included B-DEC Method Book contains lead sheets and musical charts for proficiency practice and drills. An extensively functional optional 4-button footswitch facilitates and completes this fun package for switching presets, banks of presets, recording/playing loops, tuning and many other features. Though obviously aimed at beginners, it also serves the gigging musician with lots of options in great sounding 33 lb. carry. My own B-DEC is still going strong today!

​

Fender Bronco 40 - 2011-2018 - 2nd Generation
(Not a Rumble)
Shedding the beginner image, the Bronco also loses a lot of functionality compared to the B-DEC. The kickback and MIDI is gone and an optional 1-button footswitch lets you choose between either of 2 presets. But, it adds a bit more power at 40-watts.into a 10" speaker and gives new modeling facilities, including software interfaces for Fender Fuse and its community, Ableton Live, and Amplitube via USB. And a professional XLR Out assures quality recording or sound reinforcement. Bass modeling now functions similar to guitar modeling in the popular Fender Mustang amps. Software updates are through a connected computer. It's a capable, fun and gigable bass amp at just 30 lb.s.

Fender Rumble Studio 40 & Stage 800 - 2018- - 3rd Generation
(Rumble V3)
Further shedding the beginner image, the 2x10" Rumble Stage 800, at 400 watts continuous "as-is" and 800 watts continuous with one, or two(!), 8 ohm extension cab(s), is a very professional bass modeling powerhouse, but at just 39 lb.s! The included multi-functional 4-button footswitch, optional for the Studio, returns much of the fun and convenience of the B-DEC's footswitch, such as tuning, looping, preset selection, etc. In fact, the B-DEC's footswitch works on the Stage & Studio, too, and a free magnetic faceplate updates the button labels. There are more extensive amp models, effects and cab sims and signal chain flexibility. The built-in wi-fi makes internet updates easier and Bluetooth now makes aux in wireless, or lets your phone or tablet actually control your amp wirelessly! These Rumbles now totally share their software (and presets!) with the current Fender Mustang amps. The 40-watt Studio 40, down to just 19 lb.s with a 10" speaker, has all the same software, inputs/outputs and wireless facilities as the Stage 800, just not the same power amp & cab capability. And they are Rumbles! In fact the Stage 800 shares the exact same cabinet and speakers as the Rumble 500 combo, but with darker cosmetics for easy recognition. It's truly a quantum leap for bass modeling and for Rumbles!

Fender Rumble LT25 - 2019- - 3rd Generation
(Rumble V3)
For the beginner once again, the 25-watt LT25 with 8" speaker at just 19.25 lb.s has a limited subset of models and presets compared to the Stage & Studio, with no wi-fi or Bluetooth and limited output to headphones and USB only. But the variety of sounds, tones and effects available are unprecedented for such an inexpensive practice-sized bass amp. Great fun that can actually encourage practicing.

Bass modeling has never been better, or more affordable, and Fender is leading the way. What a great time to play bass! Can you imagine what the future may bring?

I swear it's funny that you posted this today. I went down a rabbit hole just a few hours ago trying to find info on an amp I had briefly maybe between 2011-2012-ish. I believe it had maybe 3 onboard effects (I think it was maybe a chorus, overdrive, and some phasery type setting, it's been so long that I have no idea). Nothing crazy or fancy or that would qualify it as a modelling amp. I just remember it sounding killer for its size, and running it through my Hartke for the extra volume.

I'm sure it wasn't the Bronco as that woulda been out of my budget.

Is there a comprehensive list of all the fender combo amps anywhere online? I had no luck searching.

It seems the Bronco 40s have a following. How do they compare to the studio 40s?

That description doesn't ring any bells with me. You talkin' bass amp here? Fender, or ??

I'm no expert, nor do I know of any one particularly good resource for such a search. But one possibility though, if it was a Fender, might be the Fender Product Manuals online.

Hey fellow rumblers, is it normal to get sound dropouts on the Stage 800(headphones or speakers) that last a few seconds before coming back when the amp was paired with multiple devices?
It seems that other devices scanning for the rumble affect the amp.

I only found one thread discussing this on the web and it was suggested to not to use the Fender Tone app while connected via Bluetooth for streaming, but it seems the issue also happens when multiple paired devices are in the vicinity, which I only am able to resolve by "forgetting" the rumble in the Bluetooth settings on the device I am not using.

The symptoms almost look like the amp is asking too much from the power source and enter some "no power" preventive mode, as not just the streaming sound fades out, but also the bass on the amp.

Yet this only happens when fiddling with Bluetooth, as stated in that other thread I read, but why would the amp audio also be affected if BT fails?

If the manual stipulated that this is a "nono", I would get over it, but since I cannot seem to read anywhere else about this, I am wondering if this is worth a call to support or just a design flaw that I need to live with?

I’m wondering if he might be talking Line 6 Low Down combos. Besides the few models they offered, there was a set number of effects such as chorus, reverb, delay, and I think one more.

That’s my first thought. I’m trying to think what other brand might’ve had those other features. Anyone else with an idea?

Hey Diver. I wish I could offer you a proper response, but I’ve never had the particular trouble you’re describing. I’d definitely contact the brainiacs at Fender and request an answer to your query.

I’m always concerned with anything Bluetooth, and this would be no different. Please let us know what you find out. Good luck!

Don't leave Bluetooth on when not using it, lest someone else unwanted connects to it! When you enable Bluetooth on the amp you should immediately connect the device you want to use, which should then block other devices from affecting the amp.

Here is Fender's Invalid Link Removed:

I’m having problems streaming audio over Bluetooth to my Rumble digital amp and also using the Tone app, everything seems slow

When your device is set up to connect to your amp directly over Invalid Link Removed, you may notice the Tone app slows down and takes longer to sync with the amp.

We recommend you limit usage to either Bluetooth audio streaming OR the Tone app to control your amp presets, so they don’t compete with each other.​

FWIW, I've read this problem seems more widespread and worrisome with the Fender Mustang GT amps (the Rumble's twin brothers!) and those owners are hoping for resolution with the new TONE 3.0 App upgrade coming at the end of this month.

Because the amp audio is being processed by the digital software pre-amp, I don't think it's the power amp (the muscle) being taxed, but rather the software (the brain) receiving too many signals at once and getting confused and slowed. Whatever multi-core processor(s) our "smart" phones or tablets are using, they still cannot switch tasks fast enough between phone operations, various internet notifications, wifi & Bluetooth scanning, timekeeping, GPS monitoring, email/text/app transmissions, etc., etc., to prevent latency (slowdown/dropouts) in music.

Due to some sketchy experiences using my phone with Bluetooth speakers, I always put my phone in "Airplane mode" to keep any multitasking from interfering with my Bluetooth signal. It makes my phone focus on what I want it to do right now. (Yep, gotta download my music to stream, but it works better.) I do this whether streaming songs to the amp, or using the TONE App to control the amp. I credit this practice with my lack of any interruptions in my Rumble Studio operations.

Hope this helps.

Diver,
Yeah, I’ve had it happen a few times. The issue has been mentioned in several posts, including some of mine, between this thread and the regular Rumble thread.

As G-Dog said, it seems to be Bluetooth related. Not sure exactly what causes it to happen, but try G’s airplane mode on phone suggestion and maybe not leave Tone app on for long, extended periods if you’re not using it.

Maybe the next Tone app update will help address this. Let us know how things work out. Others are interested.

 

[Diver]

I will try all that was mentioned above, thanks for all the replies!
I have to say that the issue keeps happening after I BlueTooth turned off as well, but not after I power cycle the amp.
I am gonna do sone troubleshooting over the week end and let you know what I find out.
cheers

Well, the issue with sound fading out and back in after after seconds sure has taken a lot of my time. Bottom of the line, the amp keeps crapping out on the bass sound, now even with audio being streamed on Bluetooth. The issue happens without any Bluetooth connected or paired devices around, tried other basses, cable, keeps happening. I guess I will be on my way to GC shortly to return/exchange it, which sucks as I will be amp-less for weeks.
I'll give it another chance, but this is the 4th time Fender had me return a defective item this month, which worries me a bit about my late investments with the brand. I had to return a $2K bass three times to get it free of QC issues and it still needs a fret job and has an S curve in the neck out of factory... which now I have to drive my bass to drop it there (I live somewhat close to Corona).

I find interesting to see that MIC, MII and MIM Fender basses are getting better than 20 years ago, but my personal statistics cannot help to make me think the MIA quality is not what it used to be. That or I really pulled some bad luck with Fender...but you'd think with the money I spent it logically should decrease the odds of getting defective product in the hands of the consumer.

Let's call it bad luck ... one more time, but I really hope I get an amp that is stable for gigging after this. From what I read in this thread, this is totally something I should expect from this amp in despite of the bells and whistles. If it wasn't for the persons describing their positive experience with it, I would already consider another model to be honest.

I also hope to get an answer from Fender support as to why this issue happens. If Bluetooth really corrupts the amp's brain, it shouldn't affect the power amp for the sake of not losing audio during a gig, that or there should be a way to bypass it to use it in a simple amp/power amp configuration like a regular Rumble amp.
Can you imagine if a plane's engine would stop if the GPS stops working by example? I really hope this is isn't a bad design that cannot be fixed with firmware updates...rant over...

Your rant is legit though, Diver, and Fender needs to hear it. Now before the fanboys show up with all their stats on quality control over the years, and Fender has been quite good for as much stuff as they sell worldwide, these modeling amps are a whole other beast.

Even when they’re working it’s still it’s obsolete software we’re using. That’s why we’re so anxious for the new firmware update. And as good as Bluetooth has gotten, I still feel like I’m pulling the pun on the grenade each time I use it, in my car or on my amp. In fact, I had a dropout last night during playing and had to do a reboot to right the ship.

Now don’t get me wrong, I love the Stage 800 and I still think it is the most advanced modeler our there. I was messing with effects I’ve never tried before last night. But I could also give it up tomorrow if the computer ware if I spend more time suffering through the glitches than actually playing music. I was the same way with Line 6 and even my beloved Fender Bronco 40. I only gave so much patience with technology before it’s back to a Rumble 350 combo and a few select pedals.

I’d give Fender/GC one more opportunity to make it right and if it doesn’t happen demand a trade-in for non-modeling equipment. Then save up for a Phil Jones amp and literally never look back again!

@Diver,
You say it happens when you’re streaming audio Bluetooth and also when there are no Bluetooth devices connected.

That sounds like your having it happen quite frequently. This has not been my experience. I believe it has only happened to me when I was connected to the Tone app. That is the only way I use Bluetooth and it hasn’t happened again, to me, for awhile now.

I like the Stage 800 too much for what it does to give up on it yet.

Have you tried to see if it happens with your phone in airplane mode while using the Tone app? I’m just curious if this really may help.

I know it’s very frustrating to spend that kind of money on an amp and have troubles with it. Definitely return it or get it checked out because it sounds like something is not right with it. Good luck.

I did try it with the phone in Airplane mode, tried it with Bluetooth OFF and all devices previously paired with the rumble, unpaired and turned off. I disconnected all effects from the loop, removed the footswitch, tried different basses, cables, with or without headphones or aux cable, different power lines from the house, the only way I saw it not happen yet is when the bass is disconnected. which is not very useful lol.

I must mention that on day one, I tried to connect it to my Windows PC Bluetooth to stream directly from it, but the screen froze immediately when doing so and so did the amp after I tried to connect my phone afterwards. I power cycled and the screen never did that again.

As mentioned in the few threads on Fender forums, Bluetooth seems to precipitate some of these issues, but the symptoms are very much about what is described in the manual as thermal/ short circuit protection, though it is the only troubleshooting information to relate to in the manual:


THERMAL PERFORMANCE AND PROTECTION
Rumble Studio 40 and Rumble Stage 800 use class-D power amplifiers with thermal and short circuit protection. In the event of a short circuit, the amplifier will temporarily mute (no sound from speakers) and resume normal operation when the fault is removed. For increased thermal performance, Rumble Stage 800 has variable-speed fan cooling that starts at low speed and increases as amplifier temperature rises with playing use. Leave at least 6” clearance between the amplifier vents and other objects. If the amplifier vents are blocked or if the amp is used in an extremely hot environment, the amp may overheat and trigger thermal protection, causing temporary speaker muting. Normal operation will automatically resume after the temperature cools to a level within operating range. Under the most severe operating conditions, the amp can overheat to the point of interrupting power, resulting in a blank DISPLAY WINDOW (G) and no sound from the speakers. In this unlikely event, normal operation will automatically resume after the temperature cools to a level within operating range. Rumble Studio 40 may require the POWER switch (L) to be turned off and back on again after such a power interruption.

And yes, it happens about every few minutes, and since I cannot find a workaround to turn that off, I am assuming I have a defective unit that enters protection mode for some weird reason that I might have triggered with Bluetooth (or not) but that seems irreversible. It seems you can only revert preset factory settings, not the "brain" of the amp. Maybe a firmware flash would be my last attempt at trying to make it work, that or finding out if there is a self diagnosis test mode I can launch to see if there is an issue internally, which I assume is how Fender would assess it, but I couldn't find any info online so far.

Thanks for the feedback, the fact that you do not see it happen as often as I do comforts me in the fact there is an issue with my amp.

I was having this issue on both my Stage and GT 40 daily. I thought the last firmware update was gonna fix it, but nope. I play YouTube drum loops and audio to mine daily still but I've switched from Bluetooth'ing audio to using an aux cable, keeping my BT off, and letting the Tone app pair to my amp when it boots up. (I have no idea how it connects with BT off but it does, I've only noticed that recently) I'm going on maybe 3 weeks without the cutout issue.

It's definitely not an issue I'd expect for what we paid.

I agree. Like you, I probably would have gotten over using an aux cable for streaming audio through the amp or used an interface in monitoring mode via the Pre/Post Line out, but in my case, the issue kept happening with Bluetooth and WiFi turned off.

Well the amp is back at GC, which I bet you it will end up back on the shelf for someone else to figure out. I should get a new one in a week. Stay tuned.

I agree. Like you, I probably would have gotten over using an aux cable for streaming audio through the amp or used an interface in monitoring mode via the Pre/Post Line out, but in my case, the issue kept happening with Bluetooth and WiFi turned off.

The Bluetooth audio/video lag is the biggest reason I prefer AUX. It makes learning songs from YouTube tedious. The lag is just part of Bluetooth, not the amp.

It's an incredibly frustrating issue that has seemingly plagued GT and Rumble modellers. I didn't notice the issue until maybe a couple months before the last app update.. I thought maybe that would fix it, but it didn't. Since you mentioned it, I do recall that bit in the manual about the thermal protection. I have recently moved my amps around, it's possible my issue has been resolved (for now) by moving it slightly further from the wall. Makes sense in my case

Perhaps it wasn't the Bluetooth. I've had the Bluetooth audio compete with the Aux though when I forgot to turn my phone's BT off.

There's just so many variables that can have people with the cut out issue chasing their tail. I bet an overlooked commonality probably is placing the amps too close to walls or under desks. Like back in the early 2000's when big 36' CRT TV's were still the rage. Every new home was built with TV nooks above the fireplace. It probably wasn't the best idea.

I should've clarified a bit more about the Bluetooth earlier. I turn BT off on my phone but leave it on with the amp, but the tone app still connects. It's too bad you took that amp back or we could try to recreate whatever seems to have remedied mine. Here's to hoping the next one works fine for ya though. Don't lose faith yet!

I wouldn't bet against that, Diver. GC is infamous for sticking "returns" back on the floor, and maybe they're not the only ones, but it makes me nervous when they would tell me the floor model was the last one they had.

Yep. Sadly I returned a bass two times that had cosmetic QC issues, non leveled frets and an S curve in the neck (each time). The second one had all protective films but couldn't be setup to specs. Finally I received one that looked alright, still had fret/ neck issues and you can tell someone owned it for a while as the truss rod screw has definitely been used prior to me owning it and all protective film was gone, but least I can manage this one to get back to specs. Quite a shame for such an expensive bass.

I am not one to bash on all Guitar Center locations, as I reckon they are made of different people who care differently about their jobs.Their central inventory system is as much of a plague as it is a great thing. I mean, back when I bought my first bass, I didn't a choice of colors, let alone models. Orders were called "special order".
I would have never thought of returning a bass that had fret buzz out of the box either, so I must appreciate their return policy, but I think that policy also generated this behavior from GC.
Really my only gripe with GC is that while they are maintaining retail locations, the service is little over the one I would get from an eCommerce dealer.

@Dookieshoes , the fact I was having the issue with the amp's BT off led me to think we may have different issues, but thanks!
