- A circuit unit which takes a small signal and amplifies it sufficiently to be fed into the power amplifier for further amplification A pre-amp includes all of the controls for regulating tone, volume, and channel balance 2
- Holds controls for volume, bass and treble but has no on-board amplification
- preamp

- preamp
- An amplifier circuit that takes the signal from an instrument (or in the case of an onboard preamp, a pickup or set of pickups) and alters its impedance and/or amplitude, thereby preparing the signal for a power amp Preamps may also include EQ sections, compressors, effects loops, etc See Bass Amp Basics, July '92
