Bought it new in 05. Struggled with it for a while. Was not used to an amp you have to PLAY. Swapped speakers/tubes a few times. Settled on Scumback mix of H75-LHDC/H75, long plate Mullard ECC83 in V1 RFT ECC83 in V2 and Tesla ( not JJ) ECC83 in V3. Power tubes are a mix of a GEC Kt66 and RCA black plate 6L6GC The Scumdacks have broken in nicely but something has happened in the last few months. I have never been so taken aback by tone until now, and I have had some killer amps. I have always searched for THE tone, ever since 1982. I can't express the way I feel about this enough. I f you know me, you know how anal I am about this and how hard I have looked. I have other nice amps, but this one and the combo of parts are what I have been hunting for all these years. The tone was almost there, the FEEL is there now and that makes for a confidant player, right?
