The Sushi Box FX Secret Society

For some reason I get a weird whining noise that goes up and down in frequency when I have 2 sushi pedals on a board. I tried putting other pedals between, but I still get that funny whine that doesn’t stop going up and down.

yep, that's what happens with mine too.

as a matter of fact, my new HWDW is whining with any other pedal, even with separate power supplies.

it seems to be a charge pump/voltage multiplier issue.

 

[SemiDriven]

I've noticed that combining certain Sushi pedals produces a whine as well. When that happens, I just do some pedal swapping until I get no more whine.

Sometimes, too much of a good thing(s) can lead to whininess.

It will get figured out / fixed.

The film reference for “Shirley, you..,” was provided (very cool, thanks), but it would be a disservice to not bring it full circle and mention that the lines would be:

Surely, you …

… , and don’t call me Shirley.

If I use my Sashimi Fuzz with my Space Heater with no other pedals on in between them, I get a whine. But if I kick on my Nano QTron or Xerograph Deluxe, everything is dead silent. I’m going to try putting my Polytune 3 in buffered mode in between them and see if that kills it.

Anytime I have bad news, I like to deliver good news first to soften the blow.

So the good news is February batch is coming along great. I'm short on Sashimi, Fluffy Kitten and UA boards, but everything else I have on hand and boards are assembled and ready to throw in the boxes.

The bad news is I ran into a couple issues with some handwireds. Lab Rat, Slampegg, Space Heater, and Dr. Wattson are all perfect. Absolutely great, zero issues.

HWUA and HW Finally are both having issues. Apparently they always have and I just never noticed, because the issues only occur when the gain is turned past 2:00, which isn't something I often do. With the gain past that point there's an obnoxious high-pitched squealing sound, which changes pitch as you further adjust the gain knob.

I don't know if this helps you out any, but my Mini-Tube Particle Accellerators do the exact same thing. I need to check my Underground Accelerator and Mini-tube London Underground just for giggles. I think I've cranked the gain on my UA though with no squealing.

Anyone have Nathans shipping address? I have a pedal to return for repair, and he's been offline for a few days, not responding to messages. Hopefully he's taking a few well-deserved days off!

Yea

I just shot him a message, talked to him via other means yesterday. I know he's been heads down finishing the month order, but I asked him to swing by

Realized I never got around to posting the SushiBox Family Photo:
The HW Underground Accelerator is #001

update. Nathan PM'd me and said that if i send it back that he'll investigate what going on with the scratchy pots, bypass pop and the whining when used with other pedals.

Or could you let the client choose this as an option on the website when he orders the pedal? In the case of the Blackbird for example, I realize I moved the jumper to the "always on tube stage" position, and never need to change it.

That would either involve hacking the board apart to a point that I wouldn't feel good about it or redesigning the board and having a separate board specifically for that option.

Would this be sturdy enough when wiggling tubes in and out?

A solid question, I have no idea. I got the idea from a cheap Chinese tube pedal I have, and they have a pair of 1x3 connectors instead of 2x2 connectors. Theirs flexes a little bit with force, but doesn't feel unreliable. I think the 2x2 would be sturdy enough, but I would of course get one prototype done to verify before trying to convert everything I do to that system.

Would this also making tube rolling easier for the end user? It looks like the whole tube socket assembly can be unplugged, or is it still soldered in place?

It's still soldered in place, but with my current design the middle of the tube lines up with the main circuit board, whereas with this one the tube sits back a ways. This means it won't be snug up against the enclosure and also means there will be more tube to grip while removing, so it will make swapping easier.

nathan,

just my suggest but PLEASE don't scissor your space heater box. the cat on guitar I'm helping on this upcoming tour got the donate from me of my first one when you brought me the hand wired version and the one word he used was "BIGGER" - I s h i t thee not and he has it always on now. great box, nathan, much respect to you. in my thinking, that baby's a keeper, it's 'pert-near like your very own pbass.

on bass, watt

I don't have immediate plans for getting rid of the Space Heater. If I do add the tone stack defeat switch to the SMD UA then I would likely get rid of the SMD Space Heater, but there isn't room in the handwired UA to add the switch, which meand the handwired Space Heater would stick around.

yep, that's what happens with mine too.

as a matter of fact, my new HWDW is whining with any other pedal, even with separate power supplies.

it seems to be a charge pump/voltage multiplier issue.

The frequency that the high voltage SMPS in my pedals operates at is around 60kHz, well above hearing range, and the HW versions should be even higher, so I'm wondering if the operating frequency of some power supplies disagrees with the operating frequency of my SMPS and imposes harmonics on the line. There is one additional filtering measure I can add that has always been out there but had felt like unnecessary overdesign. May be time for me to start trying it out. Overdesigning is better than waiting for problems to come up.

Sorry about that, I had friday off work so I accidentally pulled an all-nighter thursday night, then crashed around noon on friday, but still woke up and worked until 2AM, then passed out and slept until 2PM today.

The good news there is that of the 37 pedals in the february batch, 30 of them have finished final assembly and the remaining 7 are waiting for parts. Of the ones that are finished about half have gone through testing and every single pedal that has been tested has passed. I plan to finish testing tonight and start shipping the ones that are ready tomorrow. I will then be taking a quick break from the february batch as I have a stack of repairs/mods that need my attention and I need to get those out while I wait for parts to come in (should be just a couple days).

I did some tube swapping in SS to reduce gain in the drive channel. Quick psa for folk having trouble removing tubes - tried the duct tape trick without success - I used a plastic scraper tool to pry the tube out.

My experience with the tubes was different than others have reported, not sure what is going on: with a 12ay7 in position 2 I did not notice any difference in gain. I had to keep the gain knob at the lowest possible setting to keep from getting too much distortion. So I put another 12ay7 in position 1, and now I can turn the gain to about 1/4 before getting too much distortion. There is still enough gain for the clean channel so I have unity with bypass. IOW success! I may try a 12au7 in position 1, that’s what I have in my meatsmoke.

I have a 12AU7 in a PAx which cleaned it up nicely. For my taste (chasing Fender Showman Amp cleans) the 12Ax,At and 5751 were just over the top...

 

[SemiDriven]

Throwin' this out there....

Anyone try an SV-Pre into a SBVT (or vice-versa)?

Just wondering....

 

[4Mal]

I actually tried sv-pre into hwsh. and then hwsh into sv-pre. The parts were greater than the whole... I think the idea of dualing tone stacks is just going to be not worthwhile...

A hand wired sbvt might float my boat but for now, slampeggX is pretty groovy.

 

[Sushi Box FX]

HW SBVT may happen, but it will be difficult. I started on a design, nothing finalized though.

Not sure how many here have the Westinghouse but that into the SV-Pre is fantastic, definitely warms it up and gives t00b tone

SH into DWX for the win so far for me. And SH into the Line 6 Helix amp models I use sounds great, too. The SH makes everything sound more betterer.

Well that's cool!

So would a HWDWX and a HWSH or HWFinally be even betterer?

 

[4Mal]

@Ryan L.
hmm, maybe I'll have to move my HwSh to the front of my chain...

I've been running my Future Impact in one of the Stomp Efx loops. Maybe I should go Lehle bass Switcher=> SH => Bass Comp => FI => Stomp and put the SlampeggX in one loop and the Pax in the other.

My Stomp needs are so minimal but the x-over split has me addicted. More switches and blocks. the LT is beginning to look sweet but then your rig with 4 efx loops... DANG
