This Deluxe Reverb is in very good condition, with light signs of previous wear. This is from 1974, which was before some of the heavier changes to the AB763 circuit went down. This is a good value buy, when compared to the prices of blackface amps currently - and many would argue the sound is very close. Internally, it has changed filter and bias caps, but is mostly original otherwise, retaining all of it's stock resistors and coupling caps.
