Description

Dunlop produced the M85-U as part of the MXR Bass Distortion line, positioning it as a dedicated bass distortion pedal designed to preserve low-end signal while adding heavy distortion. It sat within the MXR effects range as a bass-specific unit, offering the player control over both the wet distorted signal and the dry clean signal independently.

The pedal provided silicon and LED clipping options, giving the player a choice of distortion character. Separate Dry and Wet level controls allowed the clean low-end content to be blended alongside the distorted signal. The unit ran on a standard 9-volt battery or an ECB003 power supply, drawing 11 mA. True hardwire bypass kept the signal path clean when the effect was disengaged. Input impedance was rated at 1 MΩ, output impedance at 315Ω at 1 kHz, with a signal-to-noise ratio of 90 dB, distortion gain of +40 dBV, and dry channel maximum gain of +16 dBV.

For questions about power supply compatibility, signal chain integration, or general servicing of the unit, a qualified electronics technician familiar with effects pedals is the appropriate point of contact.

From the people who own them

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.
