What is your opinion of this product?
I've had the half stack for over 2 years now no problems of any kind. Anyone that tells you these sound "too digital" at hi volume or other negative comments simply doesn't know how to use this amp. this amp is for TWEAKERS, you have to dive in and deep edit, the pedal is a must, I play everything from 50s doo wop, 60s surf, 70s-80s classic rock/metal to full blown death metal and this amp DOES do it all and do it darn well. one of the bands I play with we put silk screens in front of our amps for stage look, had a local tube snobby ask me what I was running to get my awesome tone, pulled back the screen and showed him my spider4 and he about fell over.
