Boost - EF86 Tube Pedal

$249.00

The BOOST is a boutique all-analog vacuum tube pedal using a pentode to deliver warm, clean gain for overdriving amplifier inputs or other pedals. A simple tone control lets you contour the result, helping to prevent muddiness and maintain punch. Primarily designed for studio use, this pedal offers superb signal-to-noise performance, implements true-bypass, and provides a buffered output capable of driving long cables or other pedals with ease.

Hand built in USA.

Reviews

"Great sounding all-tube gain that you can add in front of an amplifier or to other pedals on your board, to kick the front-end and drive 'em into more saturation and overdrive ... My little silverface Princeton which sounded killer too, I had the Princeton cranked up to about 7 or 8 and then just cranked up this pedal in front of it and nailed it. Was able to get the ah, you know, the Princeton to scream. It sounded really cool" - Pete Thorn
