Fender Rumble Club

Those JB4s call me a bit, though there seem to be mostly Fretless ones - like yours? Fretless scares me a bit, not that I have any cash for one anyway. :)

The MGB is cool also - looks like the JB4 but active. So a bit closer to the CC LLB.
Yeah the MGB was used by a bass player here 80's and 90's from memory by Adelaide band Chunky Custard..had a black one I think it was...sounded great.

Hey guys, in another thread, someone mentioned the master affects the line out, is that true? I thought it was only gain and EQ going out the line out ...
The XLR line output on many—if not all—of the Rumble series amps (V3) is post all controls, including the Master. See the attached block diagram from the manual. Rumble.png

Thanks! I was just looking at that, but couldnt tell where the master is in the chain. (We were discussing 100 and 200 combos)


Yes, the Master Volume does affect the XLR line out on the Rumble 40 thru 500, but it's apparently not as drastic as some may expect. See real life experiences in the Rumble XLR Out Volume Levels section of the wiki page.

The Studio 40 & Stage 800 each give you both a pre & post XLR out with no Master affects (default mode), or you can choose stereo XLR outs. The Rumble 800 HD gives you a pre/post switch on the XLR out with no Master affect.

Thanks! Plenty to comb over here!

It's not my own personal preference, but as G-Dog says, the action of the control is not drastic, particularly once you've dialed in a ballpark setting on the master.
Frankly I never even noticed! I recommended a rumble, and the other guy brought it up. We run our own PA and try our best to "set it and forget it" so any mid show changes are minor.

My small bands, where we ran our own PAs, all appreciated getting a post-eq signal; less work for whichever one of us ran the PA. My bigger bands, using various soundmen who often requested pre-eq signals, never seemed to have a problem when I sent them a post-eq signal instead!

I work hard on "my sound" to fit the songs, that's my job. So that's what I want going to FOH, like miking the cab but, without the mike. Now, whatever the soundman feels he has to do with that, well, that's his job, not mine. Ideally, a gig will have some, maybe a lot(!), of dynamics not just of volume but of tones, also. I've not seen many soundmen who are nearly as dedicated to that, for each instrument, as the musicians themselves.

Just my 2¢.

Here are some numbers: With a nominal -40 dBu test tone at 400 Hz into the input of my Rumble 100 combo, all controls flat (12 o'clock position), I plugged the XLR output into a balanced input of a line level mixer and set the level to read -6 on the VU meter. Rotating the master clockwise from 12 o'clock to 3 o'clock raises the level by 9 dB to about +3VU. Rotating the master counter-clockwise from 12 o'clock to 9 o'clock reduces the level by about 12 dB to -18VU. So under these admittedly primitive test conditions, the sweep from 9 o'clock to 3 o'clock induces a change of about 21 dB (with steady-state tones, VU are equivalent to dB for all intents and purposes).

BUT, if you set the level on your sound reinforcement system after ballparking the master at, say, 12 o'clock, you're only changing that level by +9 or -12 dB even with fairly substantial changes in the master level. If your mixer channel fader is set at the unity gain position, there would be no adverse effects on clipping by raising the amp's master level as above, or on audible noise by lowering the amp's master level, with just about any well designed mixer. It's noteworthy that rotating the master control past 3 o'clock to the extreme clockwise position has little to no effect on the measured output level from the XLR line output (less than 2 dB), with my 100. That may be a result of the built-in delta-comp limiter, but with a -40 input signal, I doubt it.
 
Direct question: Can I add an extra cab to my Fender Rumble 200 V3 combo? Is it the same size? Will it look like an even stack?

Thanks.

The 2x10 is the same size.


As richy says, only the 210 extension cab is the same size as your Rumble 200 combo. The 112, if you can find one, is the same width & depth, but shorter height. The 115 and 410 cabs are bigger. See the Extension Speaker Cabs section of the Rumble Wiki for examples.
