First of all, I really do not recommend this, as this will void the warranty on the 800c. Secondly, as the chances of obtaining the driver are exactly zero, it would be a fairly pointless exercise anyway, and certainly not worth voiding the warranty for.
I played my new Rumble 100 at a corporate Christmas party gig on Saturday night, taking a chance on it being up to the task with a drummer, two guitars and no PA support. Happy to say it was. The guitar players were using small amps as well and being a private party I knew the volume level would reasonable. Nice to confirm the 100 is able to handle those kind of gigs and an incredibly easy load in/out.
We play small-ish places with 55+y/o crowds. My R100 has become my main amp.
So I hope this is the right place to ask this, being the Rumble club and all.
I have a Fender 100, love it, lightweight and more than enough power for our needs. We are a 3 pc with bass/guitar/cajon and all 3 of us sing. So stage volume is not an issue and we are covered with one floor wedge for monitors.
But here's what I've run into. The DI out is post all controls on the amp. So in order to get good levels into the board I have to have the master volume up much louder than necessary for a stage monitor. If I set the stage volume where I'd like I get lots of line noise/hiss introduced at the board.
I tried a Sansamp pedal and maybe (probably) I'm just too ignorant of how to use it properly but didn't solve my issue in a good way. Just seems no matter how I set it I didn't get good results.
When we're outside a little extra volume on stage is workable. But for many of the indoor venues we play at it's just too much. Like Sat night we were at a brewery with cement floors, high tin ceilings, etc.
So, has any of you with a Rumble installed an attenuator internally before the speaker? With the idea being I could use the volume as set up to get good signal to the board but than insert an attenuator pre-speaker for stage volume. That would mean installing something like this in the amp and then either jumpering it for normal use or put an attenuator in line.
This looks like something I'd attempt to keep this amp but just wondering if anyone else has tried it with their Rumble. And if so what attenuator did you use? Thanks

I'd expect a preamp pedal to be a great solution. Set your amp EQ to flat, buttons off, etc. SansAmp EQ to taste, run the DI to the PA, and the output to the amp. Is that what you did? What wasn't doing it for you?
I tried all sorts of combinations with the Sansamp pedal I had, including advice from a couple people who were smarter than me. Always had the same result of low levels at input to board which meant noise/hiss when turning up fader.
I have tried a plain/passive DI box I had on hand and it works OK, but the straight signal in has a "sterile" quality that I don't know how else to describe. Noticeably different from the sound out of the DI/amp. We used to have a guitarist with a Marshall and I remember installing a powersoak between his head and cab to bring his volume down. That's where I kind of got the idea for this rabbit hole.
At the risk of sounding flippant (don't mean to...), Fender has Rumble 40s on sale for $200.

I use a sansamp with my R100 that way and it works great. Bass>sansamp>Board via XLR, but also to the R100 via 1/4" from the sansamp. That way I can adjust the R100 volume as my stage monitor without changing the signal to the board, and therefore, PAs, etc. I use the level on the sansamp to adjust the signal going to the board.

I have a 40 that I use for restaurant/lounge gigs. We always use a drummer, but-if anything-he doesn't play loud enuff, so no problem.
Low levels out of both the amp and the pedal makes no sense unless it's something weird at the board, since you're getting enough volume from the bass through the amp.
I've never heard of anyone using a Power Soak with a SS amp. It gets used with tube amps more because you need the amp cranked to get the tone you want (over-driving the output tubes, which isn't a thing with SS amps). I'm not saying it couldn't work, just that there should be an easier, less expensive answer.
Yes, the power soak I mentioned was to calm a madly loud Marshall tube head. Just where the idea came from.
As I said, there's a high possibility that I just never found the magic setting I needed with a Sansamp. Seems since I'm not that smart my best two choices are a Rumble 40 or doing this conversion for $20 in parts, plus an attenuator, and a little time.
I'm guessing that your PA doesn't have an input gain you can just turn up so you can run the Rumble at a better/lower volume. You might try running the effects send to the PA and see if you get better results. The amp would still run as normal. Also, have you tried a different xlr cable?
It's a Mackie Profx16 board, no issues getting gains on any other sources, have used different XLR's.
So I could run the effects send to the board. Interesting. Is that pre or post the gain and volume control?
I'm not certain, but it will run a second Rumble. It might be worth at least a try.
Yep, I don't use effects so never played with the effects loop. But now that you say that I do remember someone saying they used the send to chain together two Rumbles. So I probably should have thought of that. Thanks though.

Attention: Rumble Club Wiki Edit Alert!
Thanks, @KindofBlues71. Your question above about sound comparisons of the NEW Rumble 800 COMBO reminded me that the thread that has that needs to be captured. So, the Rumble 800 COMBO Thread has been linked at the bottom of the new Rumble 800 COMBO sub-section on your Rumble Club Wiki page. This should be very helpful to anyone considering the new COMBO, but especially to those already familiar with older Rumble models.
I'll continue looking for more useful links about this great new amp! When I search for "Fender Rumble 800 COMBO" I continue to get mostly links to the Rumble Stage 800! Thanks,7ender, for the confusing model names.
