Hi I have a ABM300 head soon to be running into a Schroeder 1210 4ohms and i was thinking of adding a power amp to drive the 1210 a bit harder for any gigs i get that the ABM cant handle (in 3 years 300watts in to 8ohms 1x15 has been enough). Im not looking for more than maybe 500-800watts, just something to give me a bit more headroom. im in the Uk so would rather order here but would like to keep the price low (say no more than £500). Is this pratical? thanks Dave.
