Hi, i have a 1980 JMP 2203 head, and im going to get her retubed, but im not sure which preamp tubes to go with since im new to the tube game. i believe theyre 12ax7/ecc83's. im after kind of a beefed up page tone with more bass, or a slash type tone with less searing gain compared to appetite. I was looking at grooves tubes but cant really tell the difference between the gt-12ax7-r, r2 and r3. any body have any suggestions?
