My Blistertone was packed and sent to "Groovy guitars" yesterday with a couple of PRS from my collection, so I could acquire a 1961 Gibson LP/SG in trade.
Of all my custom PRS amps, the Blistertone was the most expendable. I had the 1X12 combo...and to be honest...with the MDT, "H", HXDA and Sweet 16+...it was too redundant an amp. I found the MDT to be capable of achieving similar gain, with more flexibility. However, I never did retube it to see how it sounded with different power tubes.
