R+U+A stompbox
reamp, unbuffer and audio interface stompbox - 2015

a guitar amplifier input expects a specific audio signal. Most stompboxes alter these characteristics, changing amp’s tone and bias. This passive stompbox adjusts the signal back to a normal guitar output, thanks to a reamp and a pickup emulator circuits.
it also has a built-in 24-bit audio interface for apple 30-pin devices, allowing its use as an effect processor.
