Up for sale is a museum-grade, investment-ready flagship of modern boutique history: an exceptional Fulltone OCD v1.1, stamped with a rare low serial number #1221 from the literal first month of commercial production in April 2005.

This unit comes 100% complete with its original factory box, the original white factory protective tissue paper wrapper, and the incredibly rare original 2-page printed factory instruction sheets.

This is the holy-grail V1 Series 1 circuit that launched the global OCD phenomenon. Hand-built in the Southern California workshop, the interior chassis is hand-signed and dated 4/05 alongside the verified initials of master builder SJW.

Unlike any subsequent, heavily altered production versions (v1.2 through v2.0), the initial April 2005 v1.1 layout is famous for its wide-open, un-compressed dynamic range, an immense low-end bass response, and a glassy treble slice that behaves exactly like a roaring tube amplifier. This version utilized a unique MOSFET clipping configuration and an ultra-high impedance JFET input stage to deliver unmatched touch sensitivity and volume knob cleanup.

Condition & Authentication Specs:

• The Packaging: Complete with the original 2005 factory outer box and the original white factory protective tissue paper wrapper—a total scarcity for archivists.
• The Circuit: 100% original, untouched April 2005 v1.1 PCB path. No modifications, component changes, or re-soldering

Boxed, first-month Fulltone v1.1 models with verified build documentation represent the ultimate blue-chip asset in modern pedal collecting. An incredible opportunity to secure a true time-capsule piece for your tracking studio or collection vault.
