Description

Dunlop produced the CSP-101SL-U MXR Script Phase 90 as part of its Custom Shop series, positioning it as a recreation of the original script-logo Phase 90 circuit. The pedal sat at the intersection of vintage phasing character and updated practical features, adding an LED indicator and an AC power jack to the classic single-knob Phase 90 format.

The unit operates on 9 volts DC and draws 8.2 mA. Input impedance is rated at 470 kΩ and output impedance at 10 kΩ, with a maximum input level of −5 dBV and a noise floor greater than 95 dB. Bypass is implemented as true hardwire switching.

Owners requiring service, calibration, or help integrating this unit into a pedalboard signal chain should consult a qualified electronics technician familiar with effects pedals.

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.
