The Sushi Box FX Secret Society

If the whine is power related, what about the glassy sound when using the stomp switch or tapping on it?

That's still tube microphonics, that should still be dealt with by a new tube, I'm still planning to take care of that.

So here's my game plan: I just confirmed (had to turn my amp up enough to hear it) that my personal WH has the whine at low voltages, so I'm going to hack it a bit and try out an experiment for a LV/HV switch.

If you got a WH in March and really wanted the low voltage option, I'll get set up to have them sent back to me for a mod. If you got one in March and are okay just leaving the Volts turned up all the time, I want you to know you have my eternal appreciation and I'll find some way to make it up to you

It sounds like I might be the sole dissenting vote here... but I'll sign up on the list to send my WH back, in favor of having the "It's the Edison but with 'more'" of the WH.

Even if the frequency whine may not be quite as bad through an amp, both my setup at home and almost all of my gigs are with IEMs. The frequency whine is loud enough directly through my IEMs that I can't even tell what the WH is doing below 1:00ish, I only know it's on/off by the squeal. And I 100% can't put that noise directly into the ears of a whole group. And while I certainly wouldn't plan on parting ways with something as unique as the WH, I know as a buyer I wouldn't want to hear "There's just one thing about it: there's this whine unless you have the VOLT knob above 1:00."

Looking forward to hearing where you end up on this, Sushi!

Could this also explain some of the whine I'm getting in my PAx?

I've been thinking about that, I had a LUX a couple months ago that I couldn't get to sit at 220V like I wanted it to, it kept dropping to 60V, which in a 12AX7 means noise and lower output. It turned out to be a bad trimpot, I swapped the trimpot and it was fine. That was one of the factors that made me stop putting trimpots in newer designs (SH, Sunnday Drive X, King Nothing, BEX, etc), trimpots are more likely to fail than fixed resistors, so setting a fixed high voltage instead of adjustable seemed like a better move.

I'm not positive this is what's happening with your PAX, but it's possible.

I'm glad youre much smarter than I am. My answer would be "sounds broke..."

I know a medium-high amount about a very small number of things, my intelligence is very very limited and outside of electronics (especially the ones I designed) it's fair to consider me "pretty dumb."

Yeah, I’m leaning toward sending mine back, whether for a full refund or a future improved version. I can’t decide.

@Sushi Box FX you would cover return shipping in this case, no?

Yup, absolutely. To clarify though, the future version will not have a variable voltage, it will just be high voltage all the time. I could mod yours for you with a switch to go between the two, but I don't plan to keep the low voltage option long term.

Understood and I think that’s a good choice.

 

[moon-bass]

None of the issues are visual, that's for sure.

Just so happens I had gotten a purple PA puppy with green LED myself so needless to say, I find it quite babealicious in the X form!

You, sir, have excellent taste!

Confirmed mine (literally new out of the box 1/2 hour ago) has no whine at full volts setting. I'm fine with it as is, sounds great.

I do have some minor tube microphonics though when engaging the foot switch to turn on (or tap the switch with my fingernail).

Edit: I'll let it heat and cool a few times. What do you all think about trying a silicone damping ring on the tube?

I've used these and they've helped on some microphonic NOS tubes I didn't want to get rid of, a lot "squishier", def take up more room

@Sushi Box FX
Just wanted to confirm that the Deep Dish needs 12V and won't work with a 9V input like some of the other 12AX7 pedals?

I have been re-messing-up my board and I did run the DD with a 9V One Spot just fine. I normally use a 12V from a power block but I honestly couldn’t tell the difference and I heard enough chat that I wasn’t afraid to try out of laziness.

I've never tried them, and unfortunately looking at the dimensions I'm not sure they'll fit. The 20mm rings list the outer diameter of the ring as 1.149", and the gap in the circuit board for the tube is only 0.9".

So I just tried my TAD EF86 in my personal Westinghouse. I'm not hearing any microphonics, which is great, but I still have the whine from the power supply (albeit significantly quieter). I guess I'm going to be hacking into it to see what I can come up with. Stay tuned.

Good thing I got in on the original batch. I like the voltage backed off slightly from dimed

 

[Sushi Box FX]

Sneak peak of the Westinghouse LV/HV selector switch mod. I'll finish wiring and testing it tomorrow, I'm going to sleep.

“ Not sure I agree with your police work here , Norm “ to quote a famous movie but thank heavens Senorita Sushi is obviously , the brains of the outfit for having the great sense to marry such a standup , humble dude as the Senor ..... So happy to hear that a fix is in order and that the reviews of the WH are so positive despite the noise issue ...... Kelly

Oops, overlooked that, the rings clearly wont fit.

Thanks everyone for the kind words.

So here's my game plan: I just confirmed (had to turn my amp up enough to hear it) that my personal WH has the whine at low voltages, so I'm going to hack it a bit and try out an experiment for a LV/HV switch. If it works the way I expect it to then I'll reach out to everyone in the April batch and offer the choice between a HV/LV switch and hardwired as high voltage, no more pot. I'll probably do this for May as well, then starting in June I'm thinking I'll just hardwire them for high voltage. If the Volts option as a knob was a dealbreaker I'm happy to refund anyone in April or May that ordered one.

EDIT: Just remembered my TAD EF86 are out for delivery right now, I'll wait until I try one out before hacking up my WH, for the sake of science.

If you got a WH in March and really wanted the low voltage option, I'll get set up to have them sent back to me for a mod. If you got one in March and are okay just leaving the Volts turned up all the time, I want you to know you have my eternal appreciation and I'll find some way to make it up to you

I have an April WH and I think a switch would be a fine solution
