The FMD (Fix My Duck) is a three-in-one pedal.
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.
Sens. (Sensitivity) – varies the load on the guitar. Lower settings are darker, higher settings are brighter. This control is most effective when the Fix my Duck is the 1st pedal in the chain.
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 true bypass switch.
The FMD operates from a standard 9volt battery. Can be powered from industry-standard 2.1mm center negative regulated DC power supply.
The FMD can safely run up to 18volt DC. For example, using a 12volt DC power supply will increase the FMD’s headroom before compression. Especially useful when using guitars with high output pickups.
