Marshall Mods
Solo Boost on a JCM800 2203
Solo Boost & 2 channel mod on a Vintage Modern
I offer many different mods for Marshall amps from simple gain boosts to extra gain stages and effects loops. Tubes swaps (EL34, 6550, 6L6, KT66, KT88), re-voicing, restoring, master volumes, effects loops, preamp outs, half power mods, or basic maintenance. You name it, I do it. I work on Plexi, JMP, JCM800, JCM900, JCM2000, DSL, TSL, Vintage Modern, JVM, SLX, Silver Jubilee, Major, and 30th Anniversary models of Marshall tube amps but the JCM800 and earlier are my favorites. Email me with what your looking for and we can discuss all the options available.
