BartoliniHR-4.6AP/918 3-Band NTMB+F Preamp, 4 Pots
Independent shopping perspective
The Korena take
The HR-4.6AP/918 is Bartolini’s four-pot NTMB+F harness, built around independent bass, mid, and treble tone controls. Its low-noise circuit has a clear, transparent, strong voice, a wide boost/cut range, and a high treble frequency for the maximum available brightness. The preamp, pots, and switches are pre-wired, pre-tested, and pre-soldered, reducing the electronics assembly required during installation. Battery clips and an output jack come with the harness.
Strong match
Who this is for
- Instrument electronics installations needing independent three-band control in a four-pot pre-wired harness
