BBBoost – jFet Clean Boost


Boost. Boost. Boost – before your effects or after – it really can be used anywhere especially with a tiny footprint that fits in a 1590A box.

NEW – Interactive B.O.M Helper

We include a standalone HTML file with each of our boards that helps show you what parts go where (find it in the “Build Docs & Extra Info” Tab)- just extract the zip file to a folder and open the .html file in your internet browser. You can use the table on the left to tick off the parts as you source them / add them to the board – we found its a very handy and a big shout out to Interactive HTML BOM Plugin which is a free plugin on GitHub used to generate these.

This tiny boost pedal is based on the Tim Escobedo Duente JFET boost (which many say was the basis for the discontinued JHS Mini-Bomb). It features just 7 components including the pot and has a trim pot for adjustment.

Its so small, it fits in a 1590A enclosure and it's just bigger than a pot! (see the pics!)

It's clean. It doesn't mess with your tone. It's versatile!
If you want to really push past the drummer and be heard - you won't be disappointed with this. Use it after your overdrive to simply push that tone louder. Use is before your overdrive and really hear the pedal crank. If you've used a boost pedal before - you know how much of a great tool for any board they are - if you haven't you're missing out!!

Check out the video below for a demo on how flexible this really is.
