Fender Rumble LT25, Studio 40 & Stage 800

Quite right, RL. Like all amps with built-in XLR Outs, the PRE- connection has no, zero, zip, nada, models, effects, or EQ in the signal and no setting changes you make anywhere on the amp makes any difference in the FOH. Also, like other amps, the POST- connection has whatever models or effects the current preset on the amp is setup for and whatever changes you make to the current preset does make a difference in the FOH (my preference). And that PRE- & POST- setting is the default setting on the Stage & Studio XLR Outputs. Send the FOH, or recorder, either, or both! 😲
It is worth remembering that, unlike the POST output, the PRE output is not blocked in tuning mode, so it will be convenient to use an alternative tuner to that of the amplifier in case of sending the PRE signal to the FOH.

Hmmm, I did not know that, Riccy! But, I guess, it makes (some sort of) sense that the unaffected signal from the Input would continue on unabated through the amp to the PRE- XLR Output. 🤔

Thanks for sharing that info. I don't find it mentioned in the manual. And your wording implies that the POST- XLR Output is muted by using the built-in Tuner? How did you discover this?

A quick update regarding audio dropouts... I stopped having audio dropouts since I started turning off the amplifier before turning off the Tone APP...

Double-hmmm! Strange. I would have thought that the startup sequence would have more effect on the operating performance than the shutdown sequence. But, if that is your observation, ... ... ... 🧐

#1 - I discovered during a sound check where I had both outputs connected to FOH and we ended up not using the PRE output as it didn't allow me to tune silently.

#2 - It's not easy to find out, but perhaps if the Tone APP is turned off with the amplifier turned on, the amplifier will continue to try to recover the connection to the APP and this will also affect the next startup sequence with consequent audio dropouts... but yes, these are just my latest observations...

I purchased a Stage 800 from GC and the footswitch wasn't included. Does anyone know if the footswitch for the mustang amps is the same as for the Stage 800?

On Fender's site on the Stage 800 product page, they have the footswitch listed as the MGT-4

I was able to find this on Sweetwater, but there's no mention of it being compatible with the Stage 800, although it's listed as an MGT-4.

Yes, Eric, the MGT-4 is the footswitch usually included with the Rumble Stage 800 combo. Check with your GC to see if you should have got one!!

Also, the older MS-4 and ULT-4 footswitches are functionally compatible and, possibly, cheaper. But the older ones don't have the right labels on the buttons. Fender used to send a magnetic overlay to give the right labels to those older footswitches.

Well the Stage 800 I ordered arrived an hour before the gig. I messed with it for a few minutes, couldn't find a sound I didn't like, decided to take it to the gig.

I spent all 3 sets on preset #22 Bassman 300 Clean, I pulled the bass and treble back a bit and was happy with that sound for the remainder of the gig.

I thought it might be helpful to share a few clips, so here you go. (Go easy on me I haven't been playing that long 😬)

Jeremy - Pearl Jam

This song has a pretty involved bass line, and even a few chords that you can make out.

Possum Kingdom - Toadies

Simple bassline but I felt like the amp sounded super fat here, and I liked it.

You may want to take a look at the GTX-7. More switches. Maybe good, maybe bad, depending on whether you're a "less is more" or a "more is more" type person.

No footswitch came with my Studio 40, but I was fortunate that the GTX-7 was released before I bought a footswitch for it. I can highly recommend it. Based on other reviews I've read/viewed by users of the MGT-4 who switched to the GTX-7, not one thought that they'd wasted their money. Here's an excellent, thorough user review of the GTX-7. It's for the Mustang guitar amp, but applies 100% to the Rumble Studio 40 and Stage 800.

One quick note. When I first plugged the GTX-7 into my Studio 40, it didn't function well at all. I found out that there's a footswitch setting that defaults to the MGT-4 that you have to change to the GTX-7. After that change, it's worked like a charm ever since.

@Eric Mull, in the middle of the Stage 800 &Studio 40 Links section of your Rumble Club Wiki page there are links to a comparison of the MGT-4 & GTX-7 footswitches and manuals for each one! So, you can see what they do differently.

Stage 800 owner, new to the thread (thx G-Dog!). Just getting into the presets...but I will say the onboard tuner is one of the better I've seen in my lengthy and diverse career.

Welcome, Dave, Rumbler #1806! As you acquaint yourself to the intricacies of the various presets via the Droopy_TX Preset Experience files, you'll gain not only a deeper understanding of their flexibility, but a broad view of the extensive modeling possibilities the amp has. And this is the place to discuss them! Welcome, again.
 
Does anyone know what the "notch" setting does on the Bassman 300 Pro amp model? I really like what it does to the sound, and I would like to understand more about what's actually happening to the frequencies.
The manual says -20dB @ 700Hz.
