I hope they sound good, I’ve just ordered one! I’ll try keep the switch in place, though redunant, for looks. But, I will try and get the LED to light up; shouldn’t be hard to splice into the circuit somewhere. I’m thinking of buying a set of EMG HZ pickups to replace the old ‘select’ pickups.
I do need a new battery compartment though, mine has a broken lid!
Also, I read that these preamps could be used for both active and passive pickups.
