I've enjoyed my DG30 custom so much I was looking for another of Doug Sewell's masterpieces . The Blue Sierra was one of the initial models from PRS Custom Amp Dept . This is the model Derek Trucks plays . 50w hand wired EL 34 ( can run 6L6's) with a 2x12 that has seperate jacks (custom) so you can run it as a single 12 /share the cab with another amp or run both .. Just love the Paisley ...
