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.

Guitar Preamp: Buffer + Booster. V2 - Based on NE5534

The NE5534 is a single version of the NE5532 (which is a double op-amp).

Here is the schematic of my preamp with this thing. All other elements are the same, like in previuos (NE5532) schematic: guitar-preamp-buffer-booster-easy-to, new-guitar-preamp-project-ne5532-based.

Guitar Peamp: Buffer + Booster (easy to read schematic)

This is the schematic that I wrote about in the post: New guitar preamp project

It shows a construction of a guitar preamp with some untypical switching system and clear, warm tone.

I made it for those of you, who want some more clear and easy plan.

New Guitar Preamp Project - NE5532 Based Buffer + Booster

Today I would like to show you my new design. It's a guitar preamp (buffer + booster). It's based on the same technology like MXR MicroAmp or CMOY.

The heart of the circuit is an operational amplifier: NE5532. I was testing also popular TL071, TL072, like in MicroAmp, but it was a little bit colder and less full than the NE5532.

The NE5532 has got much higher power consumption than the TL072/071, so it should work with some stomp-box power supply.
