[2500] What is a Preamp?

Date: February 1st, 2019 | Comments : [1] | Categories: DIY.

In the last year or so, I have noticed a number of new pedals being introduced that are being called preamps. So what is a preamp, and can a pedal serve as one?

In audio applications, a preamp is a circuit that amplifies very weak audio signals to a level that will drive a power amplifier to its rated capacity.
