Hello all.
I'm looking to replace my Rumble v3 head with a Particle Accelerator. I was curious how close the baked in EQ curve matches between these two.

Those 2 eqs are as alike as apples and thumbtacks. The PA's is passive classic Fender stack and the Rumble's is active cut/boost. I am sure there's plenty of overlap, but the knob positions will be totally different. If you are boosting mids on the Rumble, the PA will not get you to the same place on its' own. Keep in mind that a Fender tone stack (PA, Underground accelerator & Dreamcatcher) is flat at 0/10/0. If you set all the controls at noon it's majorly mid-scooped.

Hey. Thanks for the response.

I'm not so much worried about how the differ (in the way of how the knobs work) as much as I'm interested in the starting point of the eq curve. For instance, when all the knobs are at noon on the Rumble. I realize the two function differently once you start turning knobs.

My "Single Slice" and replacement "More" from @Sushi Box FX came in yesterday, thank you Nathan!

My board is complete once again! I yanked a MXR Bass Distortion pedal off of it, and swapped out my Laney Black Country Customs "The Custard Factory" compressor with a "Single Slice"

That sight is pretty cool.

Is there any reason I should skip getting a Particle Accelerator? I found one for $150 in the classifieds. As opposed to getting an Underground Accelerator. It seems to be pretty power hungry, but that wouldn't be a problem for my set up.

I have never heard or owned a Particle Accelerator, and many are/have been thoroughly satisfied with that box. That said, there are a couple of reasons I would tend towards a UA.

-first, Nathan posted that the UA represents the best aspects of the PA and the (also DC'ed) London Underground in that it overdrives nicely AND preserves low end
-the tube in the PA is not user replaceable, whereas the tube in the UA is easily replaced...this not only permits end user repair if a tube goes bad, but also allows experimentation with different tube types/ gain structures. Many prefer lower gain tubes (such as 12AT7) over the stock 12AX7 in their UAs.
-newer UAs also have a tone stack bypass toggle. Since the tone stack entails a volume/output drop, the toggle can be used as a boost at the flick of a switch when/if desired

...just more deets to overthink ;)

JJ ECC803S (from eurotubes.com). It's funny, I'd had that one around for a while and tried it in different preamps but didn't like it. In the UA it seems to me it smooths out the transition into saturation and compresses before sounding obviously distorted.

Your preference may differ. Got a guitarist buddy who's into tube rolling? Ask him if you can try his collection and find out what works for you. Or just order a variety of compatible tubes (there was a good chart of them posted a few pages back, check that out). Just sticking with JJs (Nathan's preferred brand, I think) there are a lot of choices and not all that costly. Don't waste money on NO$, you can buy at least 3 or 4 new preamp tubes to try for the cost of one "vintage" one that you might not even like.

I thought that there was more then one version of the Sushi Box PA, the early one with the small tube in a horizontal position was not replaceable but then there was another version with the tube vertical up the middle that was replaceable ??
I really have no idea but I thought I had read something like that somewhere, I have never owned either one so I am speculating here.
I do have a C2CE version of the PA I built myself but that is not likely to be what is being talked about unless someone who built a C2CE version and then wrote Sushi Box on the box they put it in. (This is frowned upon as Sushi Box should never be marked on a C2CE pedal)
Hopefully Nathan will come along and set me straight so I don't mislead someone with bad advice here.
Cheers
Mick

The original Particle Accelerator used a 6N21B or 6N17B miniature tube. The Particle Accelerator X was the later version designed with a 12AX7.

Particle Accelerator is currently available as a DIY project through Conspiracy to Commit Electronics, but the Sushi Box name and logo are trademarked and I do not allow either to be used on the face of pedals built using this project. C2CE/Conspiracy to Commit Electronics is not trademarked and can be used willy-nilly.

I have a 6N21B miniature tube version Particle Accelerator based on the Fender Showman/Alembic F2B preamp circuits with the TNB tone stack and love the sound, it was my first @Sushi Box FX and afik the original Sushi Box FX product. See post #1 in this tread. I use it for recording as well as a miniature tube version of a Slampegg Bee - both sound fantastic. I also have several Underground Accelerators that I use for live, fretless, guitar and steel.

The 6N21B and 6N17B tubes are still available and they are cheap, there is absolutely no reason why the tubes could not be changed in any early Sushi Box pedal but it is a solder job and not just plug into a socket job. Any pedal with those tiny tubes can be worked on as long as you can solder and know what you are doing, or take it to any good amp tech and he should be able to do it.
At least that is my opinion but I have never worked on any early Sushi Box pedals.
