The Xotic BB Preamp Clone Kit is a DIY effects pedal kit that is based off of the veroboard layout by tagboardeffects.
It's based on two different diode arrangements, one with just two back-to-back, which would be more compressed and one with two series pairs.
We've included a switch so that you can choose either and have a centre diode lift mode for a cleanish boost.

Info regarding the original:
The BB Preamp offers a wide variety of sounds. It's capable of a 30dB+ clean boost with an adjustable ±15dB two band active EQ which adds a wide range of harmonic content to your ideal sound.
The BB also utilizes a pre-gain stage which allows the Pedal to go from a very pristine clean to a very smooth,compressed, overdriven sound.

This kit is comprised of high-quality components that have been carefully chosen to give you the best performance and sound quality from your build.
