The FMD (Fix My Duck) is a three-in-one pedal.

• It can function as a buffer pedal converting the guitar’s output into a low-impedance signal.
• Treble booster pedal. It's absolute magic at producing clarity and presence in solos even when the guitar has a ton of bottom, or when using amps that become bloated sounding when slammed hard.
• It can function as a full-range booster pedal. This mode is used to drive the front end of an amp and push the amp into its own natural overdrive.

Background:

The FMD is a pedal designed for guitar players. It evolved from a circuit that was designed for a luthier who needed an acoustic pre-amp for his 12-sensor pick-up system. When working on this acoustic preamp circuit I was looking for something different and special, so I turned to my good friend Kevin O’Connor at London Power for some guidance on this project. I am happy to say, Kevin had some great ideas and steered me in the right direction. The basic circuit I finally settled on uses JFETs. Tuned properly, it can compress in an organic “tubish”-sounding way when pushed into clipping.

I also used a version of this circuit in my K2 buffer pedal, ideal for retaining tonal integrity when driving long instrument cables.

After some experimentation, I found that cascading several of these circuits together created a very pleasant-sounding booster pedal. After another year of building one-off prototypes to get the circuit tonally worked out, the FMD pedal was born.

How it works

Sens. – Controls the FMD’s level of gain and compression. Higher settings are brighter and more compressed, while low settings are darker with less compression.

Level – Controls the output level.

Tone – Controls the high frequency.

Boost switch – Up is full range boost mode. Middle is flat, buffer mode. Down is treble boost mode.

Thin/Thick switch - Thin position is used to cut some bottom frequencies. Thick position is full range.

Footswitch – Is a high-quality true bypass switch.

Power

Can be run off the internal 9-volt battery or an industry-standard 2.1mm 9-volt center negative regulated power supply. The FMD will run continuously from an external power supply and  automatically disconnect the battery if the input jack is unplugged
