Thanks in advance for any of the sage wisdom from this board to the following question(s). I am playing a DRRI, with Mystery Brain, Monster cables. TV Jones pickups/Gent. Exclusively a Chet sound. I've had the DRRI for about 10 years, and took it in recently, and they checked and resoldered connections, replaced the preamp tubes. It sounds pretty good. I'd like to make sure I am getting the most out of it. I will say, I have the common issue of not being able to get it loud enough to make it really sing. If I turn it up to say 3.5 when home alone, great tone, but too loud. 2 is about my speed anymore (with the preamp on the MB set to basically even gain stage levels on or off) For my purposes (and I'm using my ears but would like perspective): Which channel is best (don't need reverb, with the delay on the MB) Which input is best, 1 or 2 (in either channel) What preamp tubes would you recommend (disregard cost for sake of argument) Anything else (within reason)? Thanks very much!
