This is a very early Pete Turley SL mod with 3 position tight to loose switch and a JF added switch for classic\ modern voicing. Pus it has a bright switch as well. I have kept this for so long as it is a great jcm800 module, and always been one of the best I have ever had. Anyone that has played it here said it was a great module worth owning a mts amp for. Since owning the 1959 plat. Edition module I don't use it enough and want to try others. The difference between the 59 is the SL is more compressed and has more of a lower mid gain tone. Very ballsy module that has a lot of girth, growl to it. I never thought i'de put it up but I would love to try some new stuff. Open to trades but no Marshall stuff. Would like a mark module, HW, Od, nothing super high gain. Pics to follow, can add funds to trade. Or sell for $200.
