Powered by Fretsense™

The IR-P4 is Industrial Radio's most affordable MIDI bass to date. Providing the same, world class Fretsense™ MIDI bass technology on a classic P-Bass style bass design.

Unlike the PRO-4 MIDI bass, which is composed of a USA made body and neck, the IR-P4 bodies and necks are constructed by Industrial Radio in Sydney, Australia. Purposefully designed to be both economical but well built, the IR-P4 makes our industry-leading MIDI bass technology more accessible than ever.

The IR-P4 also features a new fretboard construction that gives the bass the traditional look of a rosewood fretboard with walnut binding along a maple laminate fretboard. This makes it possible to ship the IR-P4 basses anywhere in the world without the added complexity of the new import/export permit requirements for rosewood under the CITES convention.
