Well yesterday afternoon ,....while playing my two 2204 half stacks , I had a beautiful warm tone ,..the kind you just can't put the guitar down , but finally had to because it was supper time . So to make a long story short ,.. I boiled the water to cook the pasta but forgot to turn the fan of the stove on and my place got filled with humidity ,...you couldn't see outside anymore ,...windows were all steamed. So I finish eating and started to play again and now I had this ugly cold shrill tone , the kind you want to trow the guitar away which I did ,....couldn't stand it. I'm telling you this because it reminded me when I was playing cold and humid basements ,...could never get a good tone and all the band suffered from this but from todays experience, I know now that humidity kills tone ! Also concrete in a basement is a tone killer ,...I remember putting a large rug on the concrete and it really helped . Let me know your thoughts and experience !
