Description

Dunlop positioned the MXR M109S-U Six Band EQ as a dedicated equaliser pedal covering the essential guitar frequency range. The unit featured noise-reduction circuitry and true bypass switching, and was housed in a lightweight aluminium enclosure.

Six filter sliders provided ±18 dB of cut or boost at 100 Hz, 200 Hz, 400 Hz, 800 Hz, 1.6 kHz, and 3.2 kHz, with an additional ±18 dB shelf at 16 kHz. Input impedance was 470 kΩ and output impedance 5 kΩ, with a maximum input and output level of +14 dBV. The noise floor measured -101.7 dBV, and frequency response held within ±1 dB from 20 Hz to 20 kHz with all sliders at 0 dB. Current draw was 14.5 mA. Brighter LEDs were fitted for increased visibility on stage.

Owners tracing a fault or sourcing a replacement footswitch, LED, or slider component should consult a qualified guitar technician familiar with effects pedal repair.

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.
