Re: Tech21 Character Series: anybody cracked one open yet? [schematic]

o.k here's the resistor values for the 'Goop Hybrid Module'. This little baby still had a few surprises left. R104 measured open circuit. My initial reaction was 'shit I've damaged it during the de-goop'. But no, closer inspection with a magnifying glass revealed that the laser trimming has cut com...

Re: BJFE Blueberry Bass Overdrive [traced]

just wondering. are you sure that the 2n2 on the tone circuit connects to lug 3 of the volume pot as opposed to the Jet's source as BJFE does on all of his other OD's? I noticed that the madbean Yellow Shark (BJFE honeybee), the Bearfoot and the Mad Professor 3BOD's have that cap connected to the s...

My apologies, I mixed up the labels on 9V and LED wire pads. They are reverse of what the first post is, just swap the wires. Here is the corrected image:

Re: A Switching Scheme [documentation]

Is there any advantage of using a 14 pin logic chip (40106, 4093) over using a 555 timer? It seems as though having a smaller footprint would be ideal if the functionality is the same.

My delay pedal (Boss DD3) get fizzy and low volume when activated. I suspect that the pop from the switching causes enough current to really muk things u...
