Hi folks, I just bought a diy Deep blue delay and it has alot of potential to make it on my board. I will use it as a slap back with several repeats. My question is, it's pretty dark/warm and I prefer more slice and cut to my slapback. The seller provided the build documents so I'll post em' here. Is there a resistor/capacitor that sets the brightness/ tone of this pedal? Controls are LEVEL / TIME / REPEATS with no internal trim pots. Thanks in advance for any and all suggestions!!!!
