2022-09-30 Update : If your serial is after #4050, you have access to a dip switch, on each side of the pedal, to get the "high gain" mode. All new units now have this feature.
This is our dual Overdrive based on the AnalogMan version of the Blues Breaker, the King of Tone.
This pedal have an onboard 18VDC charge pump (no need to wire it to a 18VDC outlet anymore), dual independent overdrive circuit with internal switch for Hard and Soft clipping of each channels. Internal trimpots for the presence control of each channels.
Enclosure is a 1590BB. Currently wired with 1n914, BA283 diodes and JRC4580 chip.
Power consumption : 21mA
Voltage : 9Vdc Center Negative ONLY. Using more than 9V will blow some capacitors.
This is exactly, precisely what I needed. Sufficiently transparent, wisely warming up my tone, this pedal gives my needy neck pickup exactly what it was asking for. No need for anything else, I got a killer tone, full of a nice attack, with all the warmth.
I have one side set to "wake up" every amp I play through and it adds exactly what one would hope. A little sheen , a little girth and whole lot of better. The internal clipping switches and presence knobs make for a nice amount of tweakability if you want to dial your tone more precisely. This was my first GUPTech pedal, about two and a half years ago and it's been a mainstay since.
I've had the Queen of Crow for almost 2 years now, and it hasn't left my board since I got it. Awesome graphic, and amazing sound! I can't recommend it enough.
