Description

The Fettle Boost is a JFET drive pedal that goes all the way from tasteful clean boost to full on distort-o-fuzz. The high pass switch means you can get nice crisp tones or a full bottom end. It works great by itself as an always on pre amp, or as a second gain stage.

Controls: 

Love – volume knob

Clart* – boost switch

Use this to set a baseline gain level, and the fettle knob to fine tune.  

• Left position covers cleaner boost/ drive. 
• Right position adds more gain and gets you from overdrive into serious distort-o-fuzz.

Fettle** – gain knob

Hip ass* – bass response switch. This control helps you to find your place in the mix.

• Left position – full signal
• Middle position – slight bass roll off
• Right position – treble boost

** this pot will crackle when you turn it, that’s normal.

Note – This pedal has a lot of gain and volume on tap.  If you set them both very high, you may well be pushing your amp too hard which could lead to damage.
