MoFo 55 Head

The Mofo 55 is the perfect solution for the gigging player requiring a compact, tone-packed amplifier.


Expanding on from the hugely successful MoFo 30, the MoFo 55 is designed for the gigging player who needs more. More tonal shaping, more power, more gain and footswitchable boost on either channel. From spanking cleans through to jaw shattering overdrive, the MoFo 55 covers all the bases needed by today’s hard working, hard rocking player.

Both channels have independent Gain and Volume controls and the much loved MoFo Boost can be applied to either channel, taking clean to crunch and dirty to downright filthy at the click of a button. The all-new preamp has a set of three push buttons which can be used in different combinations to affect the amount of low end frequencies passing through – dramatically changing the character of the amplifier and perfect for matching the type of guitar being used and the tone required quickly and with minimal fuss. Channel changing and boost can be controlled via front panel push buttons or by using the supplied 2-wayfootswitch.

The tonal quality benefits from the passive Treble, Middle, Bass and Presence controls which are shared by both channels, and FX send and return sockets that are conveniently located on the front panel. At the heart of this all-tube monster are 4 x ECC83 preamp tubes and a power section fueled by 2 x 6550 output tubes and huge custom made transformers.
