Let me know what you think between the Slampegg and the Dr Wattson…I was debating between those for my next, although I’d rather the SBVT instead of the Slampegg, but it will just depend on the moment.
Here's my answer: Yes! (I like 'em both!)

power supply whining issues
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.

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![]()

i did that and still got the whining.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.
i did that and still got the whining.

That Slampegg looks awesome. Nice pair.My two new hand-wired Sushi's arrived today!

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’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.
