FAQ

Sushi Box builds pedals in monthly batches. So every now and then, we open up a new month's worth of spots (somewhere around 20-40 slots usually). Once there are open slots, you're able to place an order for any non-archived pedal in the store to be built/sent to you! For a month's preorders, we try to ensure they are shipped by the 10th of the following month; so November 2021 slots would ship by December 10th, 2021. Usually they're done earlier, and very rarely does it go beyond that date. If it does, it's usually due to a manufacturing issue (from the circuit board vendor) where I have to reorder boards, but I will absolutely notify users and never hide what is happening to delay a shipment. When these slots open a newsletter will usually be sent out, so make sure to sign up either by creating an account or at the bottom of the site!bul
It's called a "trimmer" (or trimpot, or trimmer pot), but you can think of it as the "break my pedal" control. Turning it will break your pedal. But seriously, it controls voltage to the tube(s). I designed the circuit to support different tubes, so I needed a way to tweak the voltage when different tubes require different voltages. Before the pedal is shipped to you, it is set at a very specific value. If you really think you want to mess with this, please reach out to me via the Contact link above and I can give you more details.
The X series pedals became so popular, I decided to discontinue the submini tube pedals. The X series with 12AT7 tubes draw less power, are easier to self-replace, and overall have less problems (like becoming microphonic).
It's a bit impossible for me to keep every color in-stock myself, so I keep the most popular colors around. If you're looking for something different, the exact knobs I use are these: Anodized Aluminum Knob - "The Magpie" - 1/4" Smooth Shaft (12.5mm OD)
Here's a few different power supplies that people have been using without issue:
  • Cioks DC7 @ 9v setting
  • Strymon Zuma with Voodoo Lab PPAP current doubler cable
  • Truetone 1 Spot
No. All SushiBox pedals have internal voltage regulators, which means whatever voltage you send it (9-12v) it is always running at the same internal tube voltage of ~235v. If you're looking to change the breakup, you could look at replacing the tube itself. Stop by Talkbass or TheGearPage forums and ask away! Or you can also find me on Facebook
Up until now all builds have been using surface-mount (SMD or SMT) components for cost and ease of assembly. Currently these are mostly placed via pick-and-place machine in the same factory that manufactures the circuit boards themselves. There are a handful of specialty components that the factory doesn’t stock that are added by hand at Sushi Box, but the rest are done by machine. Hand-wired uses more traditional through-hole components that you’re likely to see in tube amplifiers, like carbon-composition resistors and film capacitors. There’s plenty of debate on the “sound” of different component materials and it’s extremely subjective so I won’t get into that. One very audible difference, however, is the voltage at which the tubes are run. In typical SMD builds I use 250V capacitors for cost and size reasons, so I run the circuits around 240V. The capacitors I use in the handwired builds range from 400V to 630V, which allows me to run the circuits around 350V. The difference in voltage gives the handwired circuits a noticeably warmer, fuller sound.
