Original 1970s MXR Phase 100, script logo era (pre-1977 block logo switchover). Serial #708505.

This is the 10-stage optical phaser that set the standard for MXR's Phase line — deeper, wider, and more three-dimensional than the more common Phase 90. No LED, no DC jack, true bypass — the pure early-era circuit before Dunlop-era revisions.

Condition: Good — fully functional, all original electronics untouched. Cosmetic nicks and dings from honest use consistent with a pedal pushing 50 years old.

Includes:

• Original box
• Original manual
• Original foam surround (uncommon to still have this — most get lost or disintegrate)
• MXR sticker

Getting a script Phase 100 with this much of the original kit intact is rare — most surviving units show up bare. A great grab for a collector or a player who wants the real vintage tone rather than the reissue.

Buyer to confirm any additional photos/details needed before purchase.
