Cleanest JBL I've encountered in my life. After trying to save a few bucks buying 2 ratty-assed old and used ones for cheap and having issues with each, this time, I went the opposite route - paid a premium for the best condition one I could find. I just installed it into my Avatar 1X12 (pictured last below before installing the new E120). It will be a part of my backup, smaller Jerry rig: preamp to be ordered; MC50 incoming; and Avatar 1X12 w/E120. The speaker tests fine, my "problem" is now I've got to break it in!
"For me, I think the only danger is being too much in love with guitar playing. The music is the most important thing, and the guitar is only the instrument." Jerry Garcia
Nice score Jon... I love my MC50, though I haven't gotten to play it in a while ( the cover-ish gig has demanded most of my guitar time these last 60 days).
