Hi All, I just acquired a DRRI last weekend. My 2nd time around. What a great amp! FYI - I've had a pretty fair number of boutiques over the last 8-10 years, so I know what a quality tone is. Circumstances had dictated some recent amp changes, and I ended up finding an outstanding deal on a 2-3 y.o. DRRI. It sounded really excellent as it was, but I retubed it using mostly JJs, with NOS glass in the 2 12AT7 positions - V3 and V6. This amp really exceeds what my expectations were! Also, I primarily use a '57 reissue Strat with Van Zandt True Vintage PUPs. I really like this amp! Just thought that I would share. Thanks for listening (reading).
