From the post
Xotic write about their original:
The RC Booster offers a super transparent 20db+ clean boost with an adjustable ±15dB two band active EQ which adds a wide range of harmonic content to your ideal sound. As a clean boost, it can enhance other pedals, such as "overdrive and distortion pedals", or you can crank the gain for a "crunch" sound. But, the RC Booster is an extremely transparent, where many player's find they leave it on all the time.
And you can save a couple of rows if you want to by making up your own diode wrap rather than placing them individually on the board. If you'd prefer to do that make up two 3-series 1N4148 diodes, wrap them in tape or shrink tube and solder them in as shown below.
