Thanks again for all your insights- I purchased a Pro Block 200, it arrived yesterday and I can't believe how good it sounds plugged into the RE 12 cab. Plenty of power and so detailed, the reverb sounds lovely and I will get the hang of the EQ soon. I paid $350 for it (used of course) and it came with the travel case. I can't wait to take it to a gig and see how it sounds with a band. Cheers!
