Jam Pedals Boomster Mini Boost Pedal

Written by

Boost pedals are best kept simple. The Jam Pedals Boomster certainly ticks that box with its single, chunky sounding gain dial. The more you crank it, the more you it’ll drive tube saturation and fill out your tone.

A great option to slide into your pedalboard if you’re lacking space and also lacking on oomph for your solos and leads.

As with all Jam Pedals in the range, the Boomster has some seriously tasty artwork to spruce up your rig. It both looks and certainly sounds the part.

Here's what Jam Pedals say about the Boomster:

The Boomster will cleanly boost your signal and grant you massive tone!

It can be used to fatten up your existing sound, boost you up for solos, or introduce an extra stage of organic tube saturation to your already overdriven tube amp! You can adjust the gain of the mini booster pedal with the internal trimmer.

The higher the trimmer is set, the more output and gain you get. To get the cleanest possible sound, set the trimmer all the way to the left (default setting). The Boomster can be equally effective on bass and acoustic guitars!


"As someone who likes a simple pedal that does one thing great instead of a dozen things poorly, I love the Boomster. One knob and one knob only! This pedal works great to beef up my signal with a very clean and full-sounding boost. Lately I’m finding it especially effective with my acoustic guitars, but it’s equally great when I’m rocking electric and want more gain without adding a layer of fuzz. Boomster makes my sound loud and clear ! " - Lee Ranaldo

“The Boomster has become a big part of my sound. Couldn’t live without it now.” - Ler LaLonde

"Boomster is a great sounding clean boost, alone or in combination.  What more do you need ?" - Nir Felder

"The Boomster is a very simple pedal (one knob only), but it sounds really good and do its job in a way I like !" - Eivind Aarset
