This Tanglewood had a knackered preamp with a horrible crackling, hissing and popping sound. Everything was set in epoxy so repair was out of the question and as an alternative I was asked to convert from active to passive.
I replaced the old preamp and pots with B 500k and added a 0.47 tone cap and a new barrel jack as the previous one shorted out when the lead was pushed fully in.
