Yesterday I played a borrowed Line6 Spider at a rehearsal. I had adjused the different channels (clean, crunch, rythm distortion and lead distortion) to the best of my knowledge. The clean sound worked rather OK, but when I kicked in any of the distortion channels the guitar just disapeared... I had to rise the volume of those channels soooo much and still - althougt there was a lot of "noise" from the amp - it just did not cut. I will remain a "tube nerd"
