Ibanez P20-U

The Ibanez P20-U is a compact Promethean bass combo amplifier designed for practice, rehearsal, and small playing environments. It delivers 20W of output through an 8-inch speaker housed in a closed-back cabinet, providing a focused and practical bass amplification solution in a relatively portable format.

The amplifier features a four-band tone control section with High, High-Mid, Low-Mid, and Low controls, along with a Master volume. A -10dB input pad is provided for active or high-output basses, helping reduce the input signal when additional headroom and cleaner tone adjustment are required.

For practice and play-along use, the P20-U includes an AUX input for connecting external audio sources and a headphone output for quieter playing. Its closed-back cabinet and compact dimensions of approximately 330 × 350 × 310 mm make it well suited to home practice, lessons, rehearsals, and other situations where a straightforward bass amplifier is required.
