Description

Dunlop positioned the MXR M108S-U Ten Band EQ as a signal-chain equaliser compatible with both guitar and bass rigs. The unit shipped with ten filter bands and a second output, distinguishing it from earlier single-output iterations of the Ten Band EQ platform.

The M108S-U incorporated noise-reduction circuitry and true hardwire bypass switching. Each of the ten bands offered ±12 dB of cut or boost, with a shelf filter at 16 kHz handling the top end. The pedal ran on 18 V DC at 48 mA and was housed in a lightweight aluminium enclosure. Input impedance measured 470 kΩ and output impedance 5 kΩ; maximum input and output levels both reached +14 dBV at 1 kHz with all sliders at 0 dB, and the noise floor sat at −101.4 dBV.

Owners requiring calibration, bypass switching service, or power supply troubleshooting on this unit should consult a qualified guitar technician or electronics repair professional familiar with effects pedal circuitry.

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.

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.
