Then I was asked about a single channel blackface AA165 Bassman, and this time the order was for a LunchBox head. The upgrades were a 50 watt 2/4/8 ohm multi-tap OT, and I surprised myself when I agreed to add an effects loop which I very seldom do. After talking with the customer about the loop I decided that it would be very useful to him so we added it to the build sheet.
