I've got the 1962 bluesbreaker and thought it's amazing when I'm playing alone, but with my band, it just sounds so thin and the sound is not cutting through even on very loud volume level, individual notes doesnt come clear and with distortion/overdrive this thing farts!!!is it the open back design that causes this? My guitars are godin ST-IV a H-S-S high output pickups and a fender 60's mexico with GFS texas pickups....with the godin, it sounds too muddy and with the fender it sounds too thin?????do I have to lift the amp?or get the amp tilter thingy???what should I do? Is modding the power tube to 6V6 like the original bluesbreaker a good thing?is that the 6V6 or something else?I cant remember..
