I just bought a year old 65 DR from my neighbor for $250. What do I have to do to make this thing useable for harp? I'm going to run a EV RE-10 into for for blues. For blues shows, I normally play through a 64 Deluxe Reverb but it's not mine. The '64 sounds awesome but the new one doesn't have the same bite. Thanks Chris Michalek www.michalekstrone.com
