    Sc20h treble resistor

    Hello everyone! I’m on vacation and thought about spending some time with my amp.

    Jcm 800 Speaker Selection

    Got an 89' jcm 800 2x12, dumping the 75's and going to upgrade to either a g12 65/creamback 65 combo or the big daddy EV. Any ideas? No interested in the V30 or the greenback 25's. The EV'S will increase my cab weight by 70lbs or so, Damn! I think I just answered my own question.
