Description

Dunlop produced the EVH5150-U MXR Overdrive as a compact drive pedal positioned within the MXR effects line. It was designed to deliver a range of overdrive and distortion tones by way of a multi-stage MOSFET circuit, placing it in the higher-gain segment of the MXR pedal catalogue.

The signal chain incorporated a 3-band EQ — bass centred at 30 Hz, mid at 650 Hz, and treble at 10 kHz, each with ±5 dB of cut and boost — alongside a Boost switch adding +6 dB of preamp gain. A noise gate was integrated into the circuit, bringing the noise floor down to -93 dBV when engaged versus -76 dBV with the gate open. Bypass was handled by true hardwire switching. The pedal operated on a standard DC 9-volt supply, drawing 12.5 mA in bypass and 14.5 mA with the effect on and gate engaged. Input impedance measured 740 kΩ and output impedance 1 kΩ, with a nominal output level of -22 dBV and a maximum of 0 dBV.

Owners sourcing a replacement power supply should note the DC 9-volt requirement and confirm polarity before connecting. For internal servicing, MOSFET component matching, or any wiring work, a qualified electronics technician or guitar technician familiar with effects pedal circuitry is the appropriate resource.

Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.

Put yours on the record.

The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.

What do you know about this one?

Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
