Design Your Own Guitar Booster

This post is about construction of op-amp based guitar boosters and preamps. You will get here some information, about how they are made, and how you can design and make your own. It's not only about just clean boosters. It's also about mid boosters, treble boosters and bass boosters. Quite useful knowledge for beginning guitar pedal makers.

Here is the schematic of the basic op-amp based booster/preamp. It has got a bypass switch and a volume/boost control potentiometer. I also marked the places, where are frequency filters and the maximum gain control.

Multipurpose Guitar Preamp (With a TL071 Op-amp)

I would like to show you the diagram of a simple guitar preamp unit. It's based only on eight parts (including TL071 op-amp).

The preamp is very flexible in use. Can be mounted in a guitar body - as an on-board preamp or as a part of a guitar effect pedal. It's got low power consumption - perfect stuff for work with a battery.

The preamp is based on a very popular circuit, but with this diagram you will get the clear „how to” that you can easily use in your work with guitar electronics.
