The Sushi Box FX Secret Society

I prefer pedals that come in an unmarked white cardboard box.

I have an airtight 70 liter box in the garage that is chuck full of pedal cartons, along with the case candy that came with them - and I don't even own that many pedals (from a pedal breeder's perspective, at least)

I like unboxing as much as the next man, but actually it's more convenient when the pedals come 'in the nude'.

i just received my HW Dr Wattson (my second one) and it has power supply whining issues just like the first one that i had when used with any other brand of pedal, even with a separate power supply, but it's even worse (extremely loud) when used with another Sushi pedal. unfortunately it's going to have to go back. i really liked the sound of it alone but i often use more than one pedal.
 
power supply whining issues

every time I power on my Particle Accelerator it makes a hissy/whining sound. Most often it subsides after a couple minutes. I am new to tube-driven pedals, so i chalk it up to the sound of a tube warming up. But maybe it is something more than that...? i currently have the pedal powered by a one-spot wall-wart, daisy-chained with a few other pedals. and to be honest, i have not yet gone thorough troubleshooting with other power sources.

most often the hiss/whine subsides, but never goes truly silent.

Could it be that i am experiencing a similar power supply issue, which might be fixable?
or is this just the sound of a tube preamp warming up?

thanks in advance if anyone can clarify.

incidentally, the PA sounds fantastic for both guitar and bass!!

(maybe i just need to buy more sushi boxes to do further research ;)

FWIW, when I encounter a similar such situation, I move the "offending" pedal up/down the chain until it behaves.

If it doesn't behave, then I start thinking what other pedal combos might work. And the grand experimentation tube extravagansa experiment continues! :woot:

Make sure each pedal has it's own isolated power supply (not daisy chained) to fix any noise issues. That applies to all pedals, not just tube pedals.
 
My two new hand-wired Sushi's arrived today! :hyper:

i did that and still got the whining.

My Lab Rat X is very prone to adding noise when I have another 12AX7 Sushi pedal behind it. No other Sushi pedals do that (all my others are mini-tube or no-tube). But putting a buffered pedal right after the Lab Rat fixes that. I wonder if it's something 12AX7 related?
 
I'm gonna go rogue here: I don't actually hear any benefit to running >1 tube-based pedal in series. I get all the tubularity my ears want with 1 good pedal (regardless of whether it has 1 or 2 tubes), a well-adjusted compressor in front of it, and versatile, precise eq (ideally including HPF). I understand the temptation to believe that "if 1 tube pedal is great, more must mean much more betterer", but my ears don't prefer that. It doesn't improve the sound (to my ears), but adds complexity, increases power demands and the likelihood of noise.....just one man's opinion tossed into the ether. I do have >1 because I have >1 board, >1 head, and like variety.

I'm starting to lean in that direction as well.

But the tinkering side of me just can't help doing "what if" scenarios! :)
 
I’ve had whining issues with every tube based sushi pedal I’ve owned. Getting a dc7 solved my issues but I’ve read where even people with a dc7 still run into it. I’m hesitant to buy anymore now.

It’s definitely something that needs to be figured out and addressed.

I’ve had plenty of pedals with toobs and charge pumps etc and have never had issues like this before.

I do not necessarily want to have more than one turned on at a time. I would like to have more than one on the board with different settings to quickly adjust sound by pushing a few buttons rather than having to bend over and adjust settings. When running my SMD Slampegg and Handwired Slampegg on the same board, this was not possible. Even with just one pedal activated at a time, the squeal from just having the other pedal on the board was an issue. Love my Sushi pedals. However, part of me is tempted to sell the two Slampeggs, replace them with a Broughton Fliptop, and keep the Finally. Noting the noise issue from the Handwired Slampegg/Finally combination is not awful, but I may be just as happy with no noise by selling/swapping for a Fliptop.

I recognize I may be able to get around the noise issue by adding a loop switching pedal or buffer to my board. That is another option that I am currently considering, but not sure if I like it given that I think the Fliptop swap is likely a very solid choice.

I haven't experienced the whining with my Slampegg (and it sounds killer), but it's the previous mini tube version from right before the switch to 12AX7s. Not sure if that really has anything to do with it, but maybe by then all the issues were worked out with that version of the pedal.

I was really excited about the Westinghouse, but I did have trouble with that one. It would start whining when the volt knob was above about 11:00, and I could tap on mine and it would ping through my whole setup. Although the tap did sound kind of fun through an envelope filter, that's definitely not something I would have been able to use in a professional situation. I did not experience the same issue(s) with the Night Owl Edison I was able to check out, even though EF86 tubes were said to be inherently microphonic.

Other examples: Particle Accelerator > London Underground > PA with LA tone stack > Underground Accelerator > UA with tone stack bypass (?) > ???. Or the reports of whining issues.

I love the concepts of Sushi pedals, but as I've followed this thread, it seems like we often pay to be beta testers. There's a couple Sushi pedals I would love to pick up, but definitely holding off for reports on later versions before I plunk down any moolah.

5sg.
