Compact yet remarkably powerful Ibanez Promethean bass combo amplifier, a professional-grade solid-state combo designed for bassists who need full-sized tone in a lightweight, portable package. The Promethean series has developed an outstanding reputation among working musicians for its clean headroom, punchy low end, and transparent response that accurately reproduces the character of passive and active basses alike. This example features a durable black textured cabinet with a protective steel honeycomb grille, integrated high-frequency tweeter, and the distinctive red aluminum top-mounted control panel. Controls include Gain, High, Mid, Low, Phat, and Master Volume, along with a built-in limiter and power clip indicator for consistent, distortion-free performance. Additional features include Aux In for playing along with backing tracks, headphone output for silent practice, and rear-panel connectivity for live performance and recording, including balanced line output and external speaker capability found on the Promethean series. The amplifier has been tested and is fully functional, powering on and operating as intended at the time of cataloging. It is mounted on a Proline adjustable amplifier stand, allowing the cabinet to be tilted upward for improved stage monitoring and sound projection. Overall condition is very good with only light cosmetic wear from normal use. The amplifier measures approximately 36.5 inches wide, 15.5 inches deep, and 38.5 inches high when positioned on the included stand. A highly portable, gig-ready amplifier ideal for rehearsals, small to medium venues, worship settings, studio work, and musicians seeking professional bass tone without the weight of a traditional large cabinet. Please review all photographs carefully to evaluate condition and included components before bidding.
