The Tweed Bassman 59 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.
The Fender 1959 Bassman ™ was originally designed (as the name says) to be a Fender’s first dedicated Bass Amplifier that delivers a lot of volume without getting distorted. Over the year, guitar players started to fall in love with it as well because of its massive headroom that provides you with the famous F-cleans, and that’s one of the reasons it’s being built with a short time out from 1951 till now. Bajaman did a great job emulating this amplifier’s preamp, and we made a pcb for you to join the party.
Because the EQ is a massive part of the overall tone, it’s included in the pcb, as well as the power section after it, so prepare yourself cause this little thing can get pretty loud!
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.
