“The Time Manipulator is a programmable Arduino based Delay/Echo/Reverb guitar pedal. It uses two PT2399 delay integrated circuits to archive up to 600ms delay. Also, with the help of 4 analog switches, the internal configuration of the pedal can change: placing the PT2399 delay chips in series or parallel and adding extra features:
The code for the Arduino chip is programmed in C and it is Open-Source, so users can re-program the functionality or add new effects and share them in the forum. There are 9 effects included by default in the pedal: short delay, delay, echo, reverb, tap echo, chorus, telegraph, accelerator, and psycho. The schematic and bill of materials are public, the circuit was designed using easy-to-find and through-hole components.”
