Thanks. Is it possible/beneficial to run the UA at 18v for more clean headroom? Also, what frequencies are the bass, mid, and treble set at?
DO NOT run it at 18V. 9 or 12v only, and it makes no difference which. The voltage is regulated internally.
From the website:
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
