Well, Gents, I just got a Soldano SLO-100 and am just getting the hang of it. The tone is unique in its own way but it is a bit trebly sounding. I have not checked the preamp tubes but do you think something like JJ tubes will warm up the amp or do you recommend NOS tubes? I am also a bit perplexed about the best/correct way to utilize "Clean/Crunch" mode. Is there a foot switch to jump from one mode to the other and how do you guys compensate for the volume variation as it changes pretty dramatically from clean to crunch. I mean how do you guys manuever from doing a "Clean" number to a song that requires some "Crunch" rhythm?? Thanks in advance!!
