Project overview

The Twin Tweed 57 emulates part of a series of preamps in a box, emulating the tone of some of the most iconic amplifiers.

For this occasion, we have not only the preamp section, but we have also included the tone stack and the power section of this all-time classic.

Introduction

Not just a good preamp. It’s probably THE Fender Tweed 57 ™ you hearing in your head when you are thinking about sparkling clean sounds, and what can I say… Here is a Bajaman creation that gives you the most accurate emulation of this legendary tone in a small footprint. After all his designs, I have high expectations in his schematics, and what can I say… He nailed that one!

Because the EQ is a massive part of the overall tone, it’s included in the pcb.

Side note 2.5nf are pretty hard to source. You can use a 2.7nf and still have more than just decent-sounding emulation of the amp, and it works best in the return of an FX loop. But I still had great results to shape a clean channel when used in front of my amps.
