Fender PT-10 Pedal Tuner
This Fender PT-10 Pedal Tuner is being sold AS IS for parts.
It actually works fine electronically, but a piece of the plastic footswitch plate has broken off (see pics) which means that every now and then it falls apart.
When pressed straight up and down it's not an issue, but once you start introducing random twisting and excessive pressure, it goes.
One of the outputs is muted when the tuner is engaged. The other keeps passing signal.
