Boss TR-2 effects pedal repair and modification

As well as repairing guitar amplifiers, we also repair and modify effects pedals.

The Boss TR-2 is a good sounding tremolo pedal, but suffers from a loss of volume when the effect is engaged.

This is easily cured by changing R9 on the PCB from 10k to a lower value.

I find 6k8 works well.

This pedal also needed a new switch.
