Hi all, I'm looking for an amp head to drive my 1x12 cab. I plan on upgrading to a 4x12 when I can afford it and I would like a head that will not need to be upgraded with the new cab. The best choices I've come across so far are the Ashdown ABM500 and the Peavey Tour 700. Any advice or pros/cons? I haven't met anyone who actually uses either head.
