I’m adding the After Blaster to a build, and I would like to use the 2N5457 for added grit. In the build doc, it states that R4 will need adjustment for this. If using a J113, it has 2k4 as a starting point for R4. I’m wondering if I should go up from that R4 value for the 2N5457 and if so, what is a good starting point? I’m wiring the Red special with a Tone TwEQ and the After Blaster in a 125-B, and R4 is mounted on the underside of the foot switch. With so many wires and connections, I’m just trying to minimize the times I need to flip the foot switch over and replace that resistor.
Looking at it your IN jack tip goes to I (input of main circuit) through the circuit to O (output of main circuit) then to the DIP or DPDT switch where you can switch to either position 1 after blaster active or position 2 bypassed / off , so you could theoretically use it as a stand alone by jumpering I and O and doing away with the DIP switches
I like the idea of it as an add on to liven up an anaemic circuit and being able to boost it add more gain etc as required
