... Is the 100's frequencies graph similar to that of the 500 which is shown? That is, do you find that the true "flat" setting is more like 10 o' clock, 2,2,10 rather than the standard noon settings? I know each amp is different ... ...

The Rumble models 40, 100, 200 & 500 all have the same pre-amp, thus they easily share the same manual. Of course the different power amps and speakers will have some affect on the them sounding a bit different. But, for the graphs, most signals were taken from the FX Send, so the power amp & speakers were not involved. That's why I believe the graphs to be relevant to all four of those models, and probably the 800 combo as well.

Most Rumblers here owning these various models seem to agree that the settings for Actual Flat, approximated to 10, 2, 2, 10, do sound more flat than "all 12s", thus giving a little better basis for tweaking to suit each venue. But, certainly, YMMV (especially on an unfamiliar, previously used unit) and you should follow your own ears.

... ... can you briefly tell me how to use those 4-EQ buttons on the Bassman 150? The top ones I sort of understand but the bottom two I don't understand at all. ... ...

According to the Bassman 150 manual, the top two knobs let you select which frequencies to manipulate and the bottom two knobs let you set whether to boost or cut those frequencies, and by how much, up to + or - 15 dB.

First off I made a separate post about this topic on the Amp forum and then I thought about this subforum.

Any way ...

I just tried daisy-chaining my Rumble 100 to my even older Bassman 150. I've tried every option I could by using the effects loop as neither amp has two inputs. All I could get was sound of the one amp that I had my bass plugged into. I had assumed that I would hear the sound from both amps.

So, did I do something wrong but would this link (send from one amp to the return of the other amp) just give me sound out of one amp? If so ... what would be the reason for daisy chaining two combo amps?

What would be the cheapest way to let me play both combo amps as I have a gig coming up in two days? And safe too. Otherwise I will just use one of the two amps ... but that sort of defeats my plan.

Could I use my Corona Chorus pedal that has stereo outputs or something like that? Years ago I used a cheap "Y" splitter ... but I understand now that may rob the amps of some power and may not be safety way to link the amps.

Do you have both amps plugged into power and turned on? The secondary (or auxiliary, or slave, or whatever) combo amp must use its own power amp to amplify the signal to its speaker. Daisy-chaining this way does not turn the secondary amp into a passive extension cab.

The Bassman 150 manual specifically says, for multiple amplifiers, to connect SEND of the primary unit to RETURN on the auxiliary unit. So, if you're using a known good instrument cable for that, then you're doing it correctly.

That's also how it works for the Rumbles, except the auxiliary (or secondary) Rumble's Master levels are also bypassed just like it's other controls (unlike the auxiliary, or secondary, Bassman).

You can also try running a known good instrument cable from the SEND of the primary amp to the INPUT of the secondary amp. But the line level signal of the SEND may overdrive the input stage on the secondary amp, so you will need to reduce the GAIN on the secondary amp. And re-amping the signal this way will allow you to use the secondary preamp controls, but may not initially produce the desired results; some EQ adjustments on the secondary may be needed.

And, yes, try using your stereo pedal to go to the INPUT of both amps. Separate the amps a bit to get a good stereo separation effect. And you'll have to EQ both amps however you like, not necessarily the same way either!

You want to connect the send of amp 1 to the return of amp 2.

I'm calling the amp the bass is plugged into Amp 1.
Connect Amp 1's FX Send to Amp 2's FX Return and you should get what you want.
If the Rumble is Amp 2, its volume won't impact anything and it should just work.
If the Bassman is Amp 2, I *think* you need the volume control up on it.

This is how I daisy chain my two Rumble 100s, and it works fine - as it does for others. Assuming both amps work standalone.

 

[Ralph124C41]

I've done that exactly. I connected the SEND of the 150 to the RETURN of the 100 and nothing .... And then I reversed the procedure and used the 100 as the primary and then connected the SEND with a cable ( a good one with no problem and I used two or three other tested ones) to the RETURN of the 150. Nothing. The only sound I get, as I said, is from the primary amp in each case.

I did try connecting the stereo outputs of my Corona Chorus and that works OK. As others have said, I do have to tweak the two amps as they have different power levels and different EQ settings I imagine.

I haven't tried connecting the cable from the SEND of the primary amp to the input of the secondary amp ... but I don't see the need to do that as the pedal setup seems to be working OK. It is a bypass model so I can turn off the unit and the sound will go through unaffected. Or, of course, I could use the chorus at a minimal setting but I generally don't use any kind of effects when I play bass except maybe a bit of compression because I admit I learned the old school way of using your thumb and I still play many songs that way. A compressor does help even out the volume a bit ... but I have to use it sparingly. As others have said if you hear it compressing then you've used too much ... sort of like pepper or garlic on your food.

So my question is why won't the amps "cooperate" and act the way I was assured they would?

But the two amps together do provide a fuller sound which I like.

 

[Miles_ONeal]

There could be some control on the Bassman gating this (I can't imagine what), but I suspect there's a problem with a send/receive jack. I'm having a hard time imaging what, though. You can test the latter by trying each amp separately, running the cable from the amp's FX Send to its FX Receive. If both amps still work like that, I don't know.

BTW, how did you determine in each case that Amp2 wasn't producing sound? Basic, I know, but I'm trying to grasp all the parameters of the problem.

Just for fun, I tried running a cable from my 100’s effects out to my old Behringer keyboard amp’s input jack. It worked. I wish I brought it with me the other night as I played my first gig with the 100. It was supposed to be a small acoustic set with maybe a cajon or something mic’d up for percussion. To my surprise, when I arrived there was a drum set on stage, and he gets loud. There were no subs and the pa speakers were mainly for vocals and keys so I was on my own. I didn’t have anything maxed, gain and master were at or past 12 o’clock, eq was almost flat, and I was using my bass’s volume as needed for the situation. When the volume got louder the 100 was farting out. Pretty disappointing, but a great lesson was learned.

So, Ralph, how did the gig go? Did you use both combo amps? If so, how did you connect them?

 

[GonePlaid]

Two gigs over the weekend. Friday night, Ft. Pierce Elks. Very light "crowd". Late Friday we got a call about a cancellation(singer injured)at the PSL American Legion for Saturday night. We weren't booked, so we did that one too. They paid us an extra $100 for bailing them out. Good crowd, and a good time was had by...most, anyway. There's always someone who'll BMW.*

Well, I went to my local sewing shop and got a bag of synthetic wadding of the kind used to stuff sofa cushions. I carefully unscrewed the speaker from the Rumble 15 cabinet, and stuffed about a third of the contents of the bag into it. After reassembly, I fired up the Rumble, and lo and behold, that terrible boxy sound was gone. A little bass bost, and it sounded quite tight and nice. Of course, it's still a 15 watt combo with an 8" driver, but this improved the sound no end!

I have a Rumble 15 and did the JakobT mod today. I was pleasantly surprised at how much better it sounded.

So, six years later… thanks!

Sad day for me. Said goodbye to my Rumble 800 combo. Can’t say enough good things about that amp but decided to go in another direction with my main gigging rig. But…. Still have my Rumble 100 and two Rumble 210 cabinets. So not totally Rumbled out!

Thanks G-Dog! I put my member number in my sig.

Bass experience: Ha, nothing to brag about. I've played guitar for many years but had gotten very stale. Switched to bass about 6 months ago and am having a lot of fun. I'm mostly working on various pieces in the Bach cello suites. They are really helping with my reading and technique. I'll switch over to random 80's tunes when I need a change of pace.

Rumble journey: I bought a used Rumble 15 from GC about two weeks ago. I just wanted something small to sit next to my armchair in my office. My house is usually pretty quiet, so volume wasn't a concern. I've been on an NHØP listening binge lately, so a very simple tone is fine with me. And it cost me about as much a lunch for two at a mediocre restaurant.

So picked up one of those carbon fiber GR Bass 2x10 cabinets. 600W rated and only 18 lbs! As great as the Rumble was these cabinets are on a whole other level. Amazing tone, very focused and tight and cuts through any mix! And my back is very happy!

Amp wise I am using my trusty Genz Benz Shuttle 9.0. An old amp but sounds amazing and 400W at 8 ohm! Plus the tube preamp section and smaller than the Rumble 800HD head. OR, just picked up a Warwick Gnome 600 head. Love these amps, I also have the 200W Warwick Gnome I got as a backup. So small it can almost fit in your pocket!

Here is a pic with that Micro Warwick Gnome. Great sounding and loud for 130W @ 8 ohms.

I still have my Studio 40 for practice, but I love my AT Cube 500 combo and AT Cube 112 cab. I agree completely with "focused and tight". If I want color, I can do that through pedals.

You guys! Well, from reading the GR specs I can't say I really blame ya, weightwise. But, poisonally, I ain't got the extra scratch that those things cost!

Have y'all checked in at the GR Bass Club?

Yeah, I can't justify the cost of those t, but I'm sure they sound great, and the light weight would make loading in and out so much easier!
