SOLD - 1978 Marshall JMP 50 Dumble Ultra Phonix
This amp started out as a 1978 Marshall JMP Master Model 50 MKII Lead but was converted to a Dumble Ultra-Phonix by the great Alexander Dumble! This is the real deal folks! The Ultra-Phonix is one of Dumble’s ground up builds. Transformers, chassis and other parts are original, but the circuit is a full rebuild. This amp sounds incredible! Amazing clean tones to the biggest, creamiest lead tones you’ve ever heard. This amp can shake the room and retains is clarity and beautiful singing tone at any volume. Lots of gain on tap. You’ve gotta hear this one! Includes road case.
