hi! I am currently playing in a RATM tribute band using my beloved GK 1001RBII head, paired with a cheap 4x10 ashdown mag cab. Sometimes I think I need a deeper, more vintage tone, a slower attack and less definition... so I was thinking about selling the GK and getting an ashdown abm head... or another head... the ashdown is the first which came to mind. I love the way the GK sounds but I think the amp does not suit my band's needs. what do you think? PS I know I could get a different tone with bigger speakers, but the other band I play in needs 10s. so I'll keep the ashdown cab.
