I don't think i hurt anything, the organ is a hammond 123xl. my amp makes a few pops now and then when i play some of the lower notes but its soo much fun to have distortion and wah on the organ i dont even care if i hurt the amp. my amp is lame crate combo amp. the stuff i can make with it reminds me of the flaming lips, its just fun to reproduce these sounds without anything digital. maybe i'll record a track for you guys and show you want i'm talking about.
