Dunlop produced the CSP102SL-U as part of its Script series reissue line under the MXR brand, positioning the Dyna Comp Compressor as a revival of the original script-logo circuit for players seeking vintage MXR compression characteristics alongside practical modern additions.
The pedal carried forward the classic Dyna Comp compression topology while incorporating a bypass status LED and an AC power jack — features absent from the original script-era units. Bypass is implemented as true hardwire switching. The unit operates on a 9-volt DC supply and draws 2.2 mA, making it compatible with standard regulated pedal power arrangements. Input impedance is rated at 470 kΩ, output impedance at 10 kΩ, maximum input level at -5 dBV, and noise floor greater than -87 dBV.
Owners sourcing a replacement AC power jack, footswitch, or bypass wiring should confirm part compatibility against the specific board revision in hand; a qualified guitar technician or electronics repair specialist can advise on appropriate components and perform internal servicing safely.
STRAIGHT TALK
What Stands Out
Keep In Mind
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.
Owner photos
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.
