The Ibanez 2020 was made for a year or less starting in 1970, using stock obtained from the freshly defunct Teisco company (and recently laid off builders). It features a variety of features inspired by a wide range of guitars, showing a major leap by Ibanez in moving towards higher quality copies of big name guitars.
The bridge and Bigsby-style tail evoke 60's Hofners. The adjustable P90 style single coils pack considerable punch, and the body, while Strat shaped, is much wider, more like a Jazzmaster. Early examples have the Teisco "checkmark" style 3x3 headstock, while the last ones have an exaggerated Strat style 6 in line version. The 2020 also features block pearloid inlays and chrome, tapered oval tuner buttons (this reviewers personal favorite for comfort and style). There are no serial numbers.
The Ibanez 2020 is an uncommon example of a high quality and rare vintage guitar at an affordable price ($300-600 as of 2015). While it is unlikely to ever be as well known and sought after as the later "lawsuit" guitars, the 2020 is a distinct and important moment in the history of a major guitar manufacturer, and a true "players" instrument.
I think it should be from '68 or '69, I've got the one with Hohner-like headstock, I'm in love with this guitar. First of all, I feel comfortable. Right measure, right weight for me. The mechanics are rude, maybe rusted, but they are strong. The keyboard is ok, I've re-fretted the first five frets. Octaves pitched correctly. Then, the sound. Wonderful. Three positions switch, beautiful sound for arpeggios on the neck pick-up... and the bridge one! <3 Acid and elegant, what can I say. This guitar HAS A VOICE, talks to me, makes me eloquent.
