Amp Maker WF-55 4W Tweed Amp

Projects > Amp Maker WF-55 4W Tweed Amp

The Woodface WF-55 uses the simplest circuit design of any guitar amp ever produced: the Champ. In 1955, Leo Fender tweaked the circuit of his ‘cheap and cheerful’ Champ to create the famed 5F1, or Tweed Champ. The result was a fantastic little amp – with a warm and woody tone when clean, and a great raunchy crunch tone when the amp’s cranked.

The WF-55 uses the same signal path circuit together with a slightly modified power supply, to lower the Tweed Champ’s inherent noise level and make the amplifier cheaper to build. Just like the original, there’s one control for volume.
