Pedalboard Functions

Here’s a quick breakdown of the pedalboard functionality:

Pedalboard Controls

Analog Functionality

Issues – I don’t know alot about passive analog circuitry but now know there is a huge difference in the selection of the potentiometer rating for the volume control. It’s currently a 10K pot when it should be a 250K instead… which is closer to what’s actually inside a guitar to begin with. An incorrect selection here degrades the power of the signal.

Potential Fix – Just replace the pot but I also like the degraded effect and will find a way to mimic the circuit path even with the new pot in place.

 

MIDI Functionality

Issues – The only issue is the pitch bend wheel. It doesn’t allow for a full throw (not a physical limitation) and as such won’t transmit the full 0-127 MIDI data range. I can only assume the wheel had accessory circuitry to translate this properly.

Potential Fix – At some point I’m going to have to pull apart the wheel assembly and see if I can replace the potentiometer to the proper spec.

 

Other

Issues – None
