Check the listing for details. Juicy Boost Prototype. Condition: New. Listed at 78.00 USD. This Juicy Boost is a prototype, and is a clean guitar overdrive boost pedal. You're getting a hand-made prototype, fully-tested pedal using super lo noise FET-based op-amps with smooth top-end response.Also using an ultra low noise J-FET in the signal path for smooth response and hi signal to noise ratio.The 9v circuit gives plenty of clean headroom, whilst the treble and bass controls give plenty of tone-shaping flexibility. Great for pushing a gritty valve amp into 'screaming' territory, these pedals also provide enough grit to stand alone as an 'Edge of Breakup' crunch box.When OFF, Juicy Boost offers a clean buffered bypass. The controls are:'Squeeze' Similar to sag in a tube amp, but starting with light compression, and maxing out into a squeezed 'Edge of Breakup' grit. 'Boost' Adjustable gain boost starting with clean boost, then moving into mid overdrive grit territory.'Cug-Crisp-Flub' Pre overdrive contour switching: Cug in normal thick rock tone, then Crisp a bright tone, and finally the Flub fat woofy tone. 'Treble', 'Bass', Classic first order tone controls allowing for your tone sculpting or a tone setting that best suites your amp.'Output Volume' Main output volume when not in bypass mode (ON). LED's off System buffered bypass. Note, The Red LED could be ON, BUT not affecting your bypassed sound.Blue LED on System is in your signal path enabling all the pedal circuit functions.Blue & Red LED on System is ON, and the Boost is also enabled. Note: No battery space inside.
