@Sushi Box FX What are your thoughts on the noise/hum issues with the original GTO design I keep reading about? Did you design it out or was it never a design issue to begin with?

When it ends up happening it will be $300, so you can reserve it as a Deep Dish and make a note to the effect of "SBVT placeholder".
I hardwired some jacks up to it tonight so I could get a consistent test out of it, and something is off. I can tell it's trying to work, it sounds good, but the gain and output are both way lower than they should be. It may have something to do with the inductors I chose to replace the multi-tap transformer the original uses, I'll need to do some more reading. I'm hoping I just missed something simple and will check it out more this weekend, but SBVT might get pushed back to May.
In my experience the vast majority of hum in typical tube pedals comes from dirty power, and typically the most traditional way to power tube pedals is with an AC mains input and a transformer for both heaters and high voltage, and this is the way the original GTO does it. Using DC instead of AC for tube heater supply does wonders for reducing noise, but frankly using a high frequency switch-mode power supply (SMPS) for high voltage also helps a lot, and while high gain pedals are never silent, Black Eye is pretty dang good as far as noise floors go.
Thanks, makes sense. It’s a shame none of that makes it into discussion threads I’ve seen. You could mention something about noise on the product page, I bet guitarists have the same question given that seems to be the major drawback, aside from cost and noise which you’ve also addressed
Cant remember if you mentioned it earlier in the thread but did you ever figure out the metering for the deep dish so its leds didnt start on halfway point?
I traced out what Empress did on their meter and I'm going to try it out on Deep Dish, but I haven't verified it yet. And in my defense it's not the halfway point, it's 2-3 LEDs out of 10
Oh my bad I had a pic of a black deep dish saved that had half the leds lit up and I couldn't remember if that was where they started at or notI traced out what Empress did on their meter and I'm going to try it out on Deep Dish, but I haven't verified it yet. And in my defense it's not the halfway point, it's 2-3 LEDs out of 10

Happily trending in my own peculiar direction.
The metering on the Empress BC is my favourite of any compressor pedal that I’ve tried.I traced out what Empress did on their meter and I'm going to try it out on Deep Dish, but I haven't verified it yet. And in my defense it's not the halfway point, it's 2-3 LEDs out of 10
Anyone else around here chomping at the bit for their March order Sushi box?

Meh. March is old and tired. It's all about April now, baby!! Where's my Lab Rat???
EDIT: Ahhh crap. My Lab Rat is a May order. Well that's what I get for being a jerk.
Was lucky enough to find a London Underground on reverb. Wonder what my Bass Butler will think.
Looked at that one many times and almost bought it a few times! It's an awesome looking pedal!
I have a Slampegg for March and I bought a spot in May for a SBVT! Can’t wait to get them both!
