Boost

JFET dual booster with 3 gain modes, dual footswitchable volumes, Lo Cut/Hi Boost EQ—20mA/9V, 400g.

The Uprising faithfully recreates tube gain stage behavior using JFET technology delivering dual-booster functionality addressing players seeking transparent boost with tube-like character. JFET (Junction Field-Effect Transistor) circuits emulate vacuum tube behavior providing smooth saturation and harmonic complexity impossible with standard op-amp boost circuits. Three-way gain mode switch offers high (maximum saturation and compression), mid (balanced boost and mild breakup), and low (clean transparent boost) gain settings addressing different musical contexts from subtle enhancement through aggressive drive. Dual footswitchable output volumes (Level G, Level R) enable independent rhythm and lead boost levels via footswitches without requiring manual knob adjustments.

EQ controls include Lo Cut (removes excessive low frequencies preventing mud and maintaining clarity) and Hi Boost (enhances high frequencies adding sparkle and presence). This two-band approach addresses frequency sculpting requirements for different guitars and amplifiers where standard boost pedals lacking EQ prove insufficient. Gain control adjusts saturation amount feeding JFET stages. Input impedance >1MΩ, output impedance <1kΩ. True bypass switching maintains signal integrity when disengaged. Dimensions 100x120x50mm, weight 400g.

Requires standard 9V center-negative 2.1mm DC power at only 20mA maximum current consumption (exceptionally low draw suitable for daisy-chain power supplies), 50mA current rating. Handmade construction in Spain with anodized metal printing for durability. The Uprising targets players seeking JFET tube-like boost with dual footswitchable volumes, suitable for blues (clean boost for solos), rock (mid-gain mode for rhythm crunch), and country where transparent boost with EQ shaping enhances tone without imposing strong coloration and dual volumes eliminate manual adjustments between rhythm and lead passages.
