The Ibanez OT10 Octave is a compact octave pedal from Ibanez's Power Series 10 line, built in Japan and produced from 1987 to 19931. It sits in the octave and pitch family: it takes the guitar's signal and adds a note an octave away, blended against the untouched dry signal. RockBoard's PedalPedia, drawing on Ibanez's own material, lists it as offering both one octave up and one octave down effects2, while TONEHOME describes it as letting you "fatten your solo guitar sound by adding an identical line exactly one octave below the original"1.
What the OT10 does to your sound
The OT10 mixes two signals: the dry guitar and the octave effect. TONEHOME describes the range it covers as anything "from a mild octaver to a wild synthebass timbre", with the Edge control altering the high-frequency tone and the two volume controls letting you set the OCTAVE and DIRECT sounds independently1. The pedal was designed exclusively with electric guitars in mind, and Ibanez's own brochure material describes the result as a responsive, natural sound1.
TONEHOME also passes along a usage tip from Ibanez's own literature: "For exciting hard rock riffs, try combinig the OT10 with distortion." Players who want to try that can pair it with a distortion or overdrive pedal placed after it1.
Controls
| Control | What it does |
|---|---|
| Edge | Controls the tone, adding high end and a touch more overdrive to the octave effect1 |
| Effect | Controls the output volume of the octave signal, one octave below the input signal1 |
| Dry | Controls the output volume of the uneffected input signal1 |
The three-knob layout means the dry and effected signals can be balanced by ear rather than through a fixed blend, which is what allows the pedal to run from a subtle thickening of single-note lines to the more aggressive synthebass character TONEHOME describes1.
History and availability
The OT10 is a discontinued vintage pedal with no reissue. Units surface only on the used and collector markets, and TONEHOME's rarity rating reflects that1.
Manual and documentation
The original owner's manual survives as a PDF download in English, German, French and Japanese editions, and both RockBoard's PedalPedia and TONEHOME link to it21. For a pedal of this age, the manual is worth having: it documents the control functions and the intended use with electric guitars as Ibanez described them.
