The Sushi Box FX Secret Society

@Sushi Box FX when will the JC Emerald mods be available to order? Or is that a special request?
I mean modding boards is a little time consuming so I would probably charge a bunch of money to dissuade people from flooding me with requests for it :P trying to remember what I charged that guy. Probably not enough.

Now this i can't wait for!!
Me toooooooooooo!!!!!

Sorry I should have been clearer (blames Wednesday medication [it is Wednesday right] yeah).

I was referring to the bass friendly mods mentioned. I'm hoping to get some Marshall Major type grind and grunt.

Well it's going to be a complete redesign of the board that hasn't been ordered yet, then the prototype needs to be built and tested, so realistically probably no sooner than December.
 
Pretty much like this:

Is it consistent, like every time you pull power and cool down then power it up again it runs for 5 minutes then quits? If so it sounds like a heat-related issue, likely a solder joint failing as it heats up past a certain point. PM me if you want me to take a look at it.
So.
I know I said I'd PM ya, but I'll post it here instead.
I isolated the SD, being the only pedal in my chain.
No issues whatsoever.

I put it in my lineup, with one other SB pedal.
The issue arose.
Tried the SD in my lineup, with the other SB pedal removed.
No issues.
Tried it now, putting the SD on a separate power supply than the others,
No issues.
Tried it again that way, but with the two DWs on the ISO 5, and the SD on the 1-Spot.
No issues.

Guess how consternated my mother in law will be when a Sushi Box FX JC Emerald Secret Society with Green Led is on my Christmas list.

Btw,
The mini-tube Sunnday Drive is pretty sweet.
It delivers a dirt I love with minimal tweaking.

Once the issues got sorted, it very quickly earned a spot in my favourites list.
Yeah Sunnday Drive is a neat circuit, I really like it, but I think I sold less of those than I did Black Eye, so that was one of the earlier pedals I discontinued.
 
Just checking in for dumps and chuckles, and to note that I've been somewhat lurking, but also gigging SO much recently that I've been busy shedding new songs and things, and lurking on TB less as a result. Still got both boards capped with SBFX pedals, VERY interested in this here Glass Butterfly as the BIG BAD for my baby board, also keeping an eye out on some other designs while I slowly rebuild my budget after a birthday tour of Las Vegas and Los Angeles + a "tourcation" of Athens, Charlotte, Asheville, Knoxville, and Nashville (southern towns sher got a habit of 'ville'ifying themselves, don't they?).

The "tourcation" was a best-of-all-worlds sort of thing: low-pressure gigs that subsidized kicking around several cities over the course of nine days with a lead who guaranteed us pay and also makes fun music and who is also cool asf. I'd never been to the Moog Music showroom, nor had I ever come across Delta-8 *ahem* items of psychedelic interest, nor had I been to an East Nashville sake bar that played vinyl records of artists like Anderson.Paak and Thundercat.

The ol purple Particle Accelerator was on that tour and made my '50s Classic P honey blonde babe sound like she got sampled off a vintage LP over a hi-fi sound system :bassist:
 
Quick September batch update:

Everything has been dropped off at the post office as of about an hour ago, so tracking should start moving. If you have a September batch build and didn't receive a shipping notice please let me know as all of them should have gone out last night (or technically about 2AM this morning).
 
I put an SV-PRE up against my Slampegg, and the Slampegg won! In my setup the Broughton was dark. But when I turned up the treble to compensate, it introduced hiss - whereas the Sushi Box was dead silent and still had more bite! SV had a thickness in the lower-mids that was nice on the D & G strings around the fifth fret, and it does have a very nice overall feel. Having a mid control with selectable frequency is nice, but it lacked the clarity of the Bee. I would still recommend trying one if you have the chance. But it didn’t knock the Bee off my board!
Now I am thinking about getting in on the October run for an Underground Accelerator… for those who have tried both - would you go SMD or hand-wired?

I like Hand-wired better, but if you are going to run two on the same board, then stick with what you have already purchased. Sometimes there is oscillation noise when using two Sushis on the same board. This noise has been reported to be worse when mixing SMD and HW. It was bad when I tried to run my SMD Slampegg against my HW Slampegg prior to selling the SMD one. The noise was barely noticeable when running an HW Finally and HW Slampegg (though it was enough that I eventually sold the Finally).

For anyone starting fresh, HW is generally regarded as sounding better, but in a mix you will probably not notice the difference. At that point it becomes a question of how you will use it and if you want to spend the extra money.

My advice on the Broughton... get a bigger board and keep both :bassist:

Noting that I do not gig this board. If I start gigging again, I would likely buy a smaller board and only take what I needed for a given gig.

I can fix that. I keep telling myself I'll write up a document explaining the fix as it's pretty easy to do yourself if you know how to solder, but I haven't gotten around to it yet. I'll shoot for this weekend.

I might buy a bigger board and eventually a second Sushi when this is fixed. Looking forward to the fix. Will each Sushi need on a board need the fix? I assume the answer is yes, but I could also see it being the case where one pedal that causes the issue is fine as long as a second one is not on the board.
 
What!?!?! This should be you’re top priority. Mission number one.
Yeah I've been quietly walking a handful of people through it privately as well as implementing it on all builds from August onward, but the plan is to get a nice walk-through document put together and put up on the website.

Long story short, the problem is caused by the polarity protection I put on the power input to allow the pedals to accept either polarity, and that needs to be bypassed so the pedals become center negative only.

Long story long, I've used a couple different but similar components in that position based on availability, cost, etc., and even within the same component type there are going to be manufacturing tolerances that affect certain parameters. I haven't been able to find the exact number where the problem occurs, but basically what's happening is the circuit's ground is too far removed from the common power ground level. So you could have multiple sushi pedals with different ideas of what "ground" should be, which basically creates what we call a ground loop. If the diodes in the polarity protection were closely matched then they should still be at the same ground level and it wouldn't cause a problem, but when they're too different we see these problems. Also the ground level through this protection diode is going to differ based on the current pulled by the pedal, which means a pedal pulling more current, like a HW pedal compared to an SMD pedal, is going to be more different and more likely to have this ground loop issue.

It took me an embarrassingly long time to realize that this is what's been going on, and there's really no one to blame but me. The good news is that, like I said, it's an easy fix. You literally just disconnect the negative (most likely black) wire on your DC jack from the circuit board and connect it to the input jack sleeve instead. That's it. You move one wire and problem solved. The pedal will no longer work with a center positive power supply, but it still has inline polarity protection on the positive side so it will not be damaged and will still protect the circuit.
