The Formula 5F6 adds vintage tweed Bassman response to our range of Foundation Overdrives, giving you the awesome characteristics of this classic amp into any clean amp.
The tweed Bassman may be the most influential guitar amp of all time. Although it was marketed as a bass amp, its treble, middle, bass and presence controls and 4 x 10 configuration were perfect for guitar, as guitarists soon figured out. How influential was the Bassman? Look up the schematic and compare its preamp to that of a Marshall or Vox and you'll see!
