Digitech DSP 128 Plus SN 148065 Serviced PSU Recap 30-Day Warranty

Serviced Digitech DSP 128 Plus — late-’80s / Made in USA multi-FX rack (reverbs, delay, multi-tap, chorus, flange, EQ, and more). Serial 148065.

Why this one: PSU preventatively recapped with Panasonic and Nichicon electrolytics, full front-panel service, verified working and quiet. Audio path left stock — it already sounded great, so no circuit chase. Most cheaper listings are unserviced survivors.

What it is: Classic Digitech DSP 128 Plus digital multi-effects processor — program/parameter display, effect-select LEDs, Dry/Output/Input Level, MIDI In + Thru/Out, stereo 1/4" I/O, +4 line / −20 instrument level switch, footswitch A/B. Standard IEC mains inlet (Made in USA).

Service (this serial — 148065):

• PSU recapped with Panasonic and Nichicon electrolytics (preventative)
• Pots, switches, and jacks cleaned and serviced
• Fully tested — working properly, sounds great
• Audio path untouched — stock character
• No mods

30-day fix-it warranty: covered for 30 days after delivery against defects in the work described. If it arrives DOA or fails in normal use in that window, I’ll repair, replace, or refund. Buyer covers return shipping unless I packed it poorly or it was dead on arrival. Doesn’t cover abuse, wrong mains voltage, or mods after it leaves here.

Condition: Very Good — normal rack wear / light face oxidation for the era. One front knob is missing its cap (shaft still works fine — see photos). Photos are of this serial (148065).

Includes: Unit only. Standard IEC power cable not included (any common IEC cable works — cable in photos was for shooting only).

Packed as a 1U rack with the face protected. Ships CONUS only from Maple Grove, MN. Offers welcome — serious ones get a serious reply.
