Guitar Chord

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.

In the previous post I wrote about building an on-board buffer. This time I would like to show you some guitar wiring with this thing. 

It's not very complicated. It's based on one buffer circuit,  three potentiometers: 2x volume, 1x tone and one tone capacitor - in quite untypical value range.

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.
