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