From the vendor
Project overview
Inspired by Tweed Drive 59, this circuit allows you to have a ’59 Fender Bassman amp right on your pedalboard! All those vintage tones at the reach of your hand.
Introduction
There is a certain satisfaction when you finish building a preamp that allows you to have all the ’59 Fender Bassman amplifier’s severely saturated classic sounds without spending $10,000 in the process. Have you ever wanted to hear one of these amplifiers at maximum volume? We recommend first try it halfway!
Every time you hear about a classic, remember that it is on the podium for a reason. In the 1950s, the Bassman was perfect for amplifying a new discovery, the Fender Precision Bass. This straightforward 50-watt rig conceded the bass to hold its own onstage with drums, electric guitars, and piano, the typical instrumentation of the day. Its simplicity, great tone, excellent dispersion, and touch-sensitive dynamics are a true pleasure that won, over the years, the hearts of guitarists too.
