You may remember that great Aria Pro II TS-600 I had on the bench last week.
It had had all its electronics gutted and wired in standard passive mode and its owner, who owns another one of these wanted it back to as original as possible, which meant making a new pre-amp/boost from scratch.
It now has an active transistor boost that can be switched in or true bypassed with its own volume. It also has coil taps on both pickups, a phase switch and the 6 way rotary tone switch which works on passive and active modes and of course the three-way pickup selector and master volume and tone controls.
These things are amazing and sound great. I hope he likes it.
