MXR M-129 Analogue Pitch Transposer #2 with Pitch Readout


In stock


The MXR M-129 is a super-rare analog pitch transposer that melds digital ideas & analog circuitry to produce one of the first viable pitch shifters. Like the original Eventide H910, it’s a characterful beast that is as wonderful as it is unpredictable

I’ve spent many hours with the H910 and prefer it to the H949 and later Eventides. It lacks the deglitch circuitry of the H949 and, for my money, it’s more interesting as a result. So it is with the M-129 – it’s not a clean, clear pitch-shifter, but more of an idea generator, a tool to create the unpredictable

Like an H910, a small pitch shift plus feedback gives great spiralling pitch changes, climbing or falling. Subtle variations in the pitch shift mean it sounds different each time, giving a really organic feel

This M-129 has been refurbished by a top UK tech and will is ready now. It comes with the super-rare pitch display readout in a separate 1U unit
