FROM KOLL:

The High-Rise is a new premium overdrive with massive frequency range and incredible touch sensitivity. High-Rise responds dynamically to your guitar’s tone settings and enhances them; it doesn’t mask them. The “Steel” circuit acts as a clean boost, bringing clear, organic overdrive to any amp or pedal combination. The “Concrete” circuit delivers additional gain, grit, and saturation. Together, the two circuits offer a myriad of tonal possibilities for a wide range of playing styles. Explore and achieve new tones from each side individually, or use them together. Get higher.

The High-Rise was designed by Saul Koll and Portland effects maestro Jack Deville, with graphic design by Aaron Draplin. The knobs were custom designed by Saul and cast by Matt Haramis. It’s true-bypass and runs quietly on a 9VDC adapter or an optional internal 9V battery (run at 18VDC for added headroom and clarity). Every pedal is handmade one-by-one in Portland, Oregon.

“The clean-to-nasty range is occasionally reminiscent of a Klon—though the High-Rise has a touch more character and mid-range presence, and feels slightly more feral at high-gain settings. The pedal’s sensitivity to guitar volume and tone attenuation add more possibilities: You can essentially re-create unfettered guitar/amp tones—but with a touch of extra high-mid octane—by reducing guitar volume. Simple it might be, but the High-Rise is practical and thrilling, and for players that value economy and streamlined control of dynamics, it’s possibly the only gain solution they’ll need.”
