From the desk of Believable Audio " The JFET stage is neatly biased for a specific THD ratio, just enough hair to be tube-y but still very clean by most standards. A dual-stage IC output driver shapes the tone and ensures the output impedance stays constant as you turn the level fader. The three modes tailor the low end in a gentle way for fine-tuning of the boost sound with your guitar. Sounds great after EUNA, or as an alternate front-end to your board, makes about 18dB of gain and LOVES to be stacked with FLWR and other drives! Will happily drive cables and draws about 150mA. Still features our WHATEVER internal power supply and the build quality you've come to expect from BELIEVABLE AUDIO."
