BartoliniHR-2.4AP/918 3-Band NTMB+F Preamp, 3 Pots
Independent shopping perspective
The Korena take
Bartolini’s HR-2.4AP/918 brings the NTMB+F three-band circuit to a three-pot pre-wired harness. Separate bass, mid, and treble controls provide broad boost/cut adjustment, while the circuit is described as low-noise, clear, transparent, and strong. Its treble frequency is set high for the maximum available brightness. Pre-soldered, pre-tested electronics save the step of wiring the preamp, pots, and switches individually into an instrument; battery clips and an output jack are supplied.
Strong match
Who this is for
- Instrument electronics installations requiring independent bass, mid, and treble control in a three-pot pre-wired harness
