The quintessential push



+28db of boost. Zero change of tone. 

Dial in the amount of boost you need and punch it in. BOS1 is both noise- and click free for a smooth live experience. 

You can use it in front of your amp as a switchable gain stage to drive your guitar amp harder, or place it in the effects loop of your amp to achieve a solo level boost.

Quite simply, BOS1 is the perfect tool for your guitar solos and/or melodic playing, offering fat saturated leads without piercing anyone’s ears.

It also features a LEVEL control, which sets the amount of boost you add. 
Further, there is a toggle switch labeled ‘Std/HiCut’ that lets you select High Frequency damping. Note that the ratio between the boost Level control and the HF damping filter is linear. More boost -> more damping -> great for guitar solos!

The pedal is housed in a rugged steel chassis that is built to withstand extensive daily use and continuous touring.

We have carefully selected all components to ensure superior sonic qualities, minimal noise and reliable use for years and years. The BOS1 features our unique RFI protection.

All ¼” jack connectors are gold-plated, and all internal wiring utilizes high-quality, shielded audio cable with minimum DC resistance and capacity.

When switched OFF (bypassed), the BOS1 acts as a unity gain line driver, capable of driving even very long cables without tonal loss or unwanted coloration.

Alberto Barrero (Composer, Video Maker, Studio & Live guitarist)

“Definitely: it’s the most transparent and respectful Booster that I’ve tried. Zero coloration, zero noise, and tons of headroom.”

“I searched for a boost pedal that didn’t color my sound – didn’t sound harsh, but couldn’t find one, so I had to develop it myself. I added Hi-Cut to filter out the very high frequencies during solos. With BOS1 in front of my X3 Tube Amplifier, I have six gain stages at my disposal and I can create any sound I could possibly need.”
