Step 3Schematic, explanations
This section addresses the circuits behind the project.
Explanation:
When the circuit is powered off, the relay is disengaged, and the guitar signal comes directly through the pedal, truly bypassed.
When the circuit is powered on, the relay remains disengaged and the signal is nearly fully bypassed, with most of the signal coming directly to the output, but some part of it is amplified through the op-amp (with gain set by the "gain" knob) and sent to the PIC for ADC processing.
When the system goes into "record" mode, the ADC values are transmitted to the 23k256 for temporary storage using the "continuous write" mode, overwriting previous data if there is any there.
When the system switches back into playback mode, the relay is engaged. Audio from the guitar gets transmitted through the amplifier if the "byp/kill" switch is in "byp" mode, otherwise it is silenced. Data is rapidly read from the 23k256 and outputted to the DAC. The resulting signal needs no amplification and is directly mixed through the trim potentiometer to the output of the pedal.
The values of the potentiometers are read continuously by ADC channels on the PIC.

Its really Hard to read your schematics.
Can you send the schematics via mail or make a digital version of them please?
sry for my bad english i hope you understand :)
Thank you
