well, i just recently got a jcm800 and I love the tone, but now I just need some more overdrive...I've seen clips of a guy using a fulltone OCD and a clark gangster with a plexi on youtube and i really like his sound. I'm limited to buying from either guitar center or sam ash and i dont think they have one in stock for me to try so if anyone has used one of these with a jcm800, let me know what you think.
