Employing a passive distortion circuit based around the 741 Op-Amp (also used in the popular DOD Overdrive Preamp/250), the OD880 was coveted for its warm and natural tube-like overdrive tone. The OD880 was perfect for use as a transparent booster to take a tube-amp over the edge, offering singing blues tones unrivaled by other stompboxes. Japanese guitar legend Char (Hisato Takenaka) made the OD880 famous by choosing it as his booster-of-choice, and this led original vintage OD880's to quickly skyrocket into the $600 range on the vintage market.
Now Maxon has once again resurrected the OD880 and improved on this timeless classic. The new OSD-9 Overdrive/Soft Distortion takes the same circuit as the original OD880 (including the 741 Op Amp) and offers it up in Maxon's indestructible, industry-standard 9-Series chassis. Some modern day utility features were also added, including mechanical true bypass via a 4PDT switch and a charge pump to stabilize operation at 9 VDC regardless of input voltage, assuring consistent tone at all times.
The OSD-9 offers a bright, crisp overdrive that compliments single coil pickups perfectly. The pedal's post-integration overdrive circuit smoothly changes according to input level, offering a highly dynamic response to picking technique unparalleled in the world of stompboxes.
