29 Pedals JFET Boost

What can be said about the humble boost pedal?

It's an AC wave riding on a DC voltage and I did my very best to elevate it.

JFET is rooted in 29 Pedals deep love of FET transistors and their corresponding place in the hearts of many pieces of gear. FETs are very early solid-state devices that were designed to emulate vacuum tubes as closely as possible, and they have found their way into a sizeable number of classic pieces of gear.

As usual for 29, don't copy or emulate any of those, but start from a ground-up design.

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.

Imperial is length (depth) 3 5/8", width 3 3/8", height 2 1/8" max
Metric is length (depth) 90mm, width 85mm, height 52mm max

Same depth and height as EUNA and OAMP
