The Keeley Tube Drive is a limited, collector-grade dual-gain engine pairing a genuine 1950s Sylvania 12AT7WA high-voltage Class A tube preamp with Keeley’s legendary Super Phat Mod circuit. Built in Oklahoma City as a numbered run of 100 units with a brushed gold gloss finish, it offers rich touch sensitivity, amp-like body, and flexible dual-voice stacking. It was available for pre-sale on the builder’s site, but sold out within minutes!
Controls:
-
Tube Stage (Left): Dual triodes running in series in Class A, feeding a vintage tweed-amp-style tone stack for warm grit and touch-sensitive dynamics.
-
Super Phat Mod Stage (Right): Dedicated drive circuit delivering punch, body, and sustain while preserving the guitar’s natural character.
- Three Knobs Per Channel: Level, Gain/Drive and Tone – which allows adjusting the EQ of each channel separately.
-
Routing & Switching: Switchable effect order (Tube into Drive or Drive into Tube) via a simple foot gesture or an external Remote jack (Tip assigned to Drive, Ring assigned to Tube).
-
Hardware & Maintenance: Standard top-mounted jacks, a vented rear-panel jack plate for airflow, internal high-voltage conversion powered via a standard 9V DC (min. 500mA) supply, and a tube extraction pin with an included Allen key for easy tube swaps.
Early product features and hands-on reviews praise its striking visual execution and the dynamic interactivity of combining a true tube stage with a transparent, punchy overdrive. Reviewers highlight how the switchable routing order and remote switching capabilities turn a boutique collectible into a powerhouse for professional, modern pedalboards.
