The Canny Fettle Boost is a super broad ranging gain pedal that is simple to use, and spans every level of dirt from tasteful clean boost to distort-o-fuzz. This ‘Canny’ version is an expanded take on the original Fettle Boost circuit.
The right hand side (Fettle) is a tastefully voiced JFET drive.
The left hand side (Clart) is a single transistor gain stage that goes from clean boost to full on nasty distortion.
In the original Fettle Boost, the ‘Fettle’ is always on and the ‘Clart’ is accessed by a small toggle.
This expanded version, with its two independent foot switches offers 3 different drive sounds from one pedal (just Fettle/ just Clart/ both).
Fettle side
Fettle* – gain knob
Hip ass** – bass response switch.
This control helps you to find your place in the mix.
Down – full bottom end
Middle – slight bass cut
Up – treble boost
Lop-ass** – treble cut switch.
This control helps you control the brightness of your signal.
Left – no cut
Middle – slight treble cut
Right – heavy treble cut
Clart side
Clart – volume knob
Hip ass** – bass response switch.
Does the same thing as the hip-ass switch next to it (details above)
Dunsh** – gain boost switch.
Increases gain, sustain and bottom end. Before you flick this switch it might be a good idea to turn the clart knob down. The difference in gain is significant!
Left – no dunsh
Middle – a little dunsh
Right – full dunsh
* this pot will crackle when you turn it, that’s normal.
** there might be a popping sound if you flick these switches when the pedal is on.
