Onça is a class A single ended amplifier in a box, using a pair of JFET's in the place of tubes. Onça breaks up just like those classic little tube amps - there's no diodes doing any clipping here, just true organic overdrive. Super compact & simple to use, you really only need the one volume knob as you can use your guitars volume pot to clean it up & your guitars tone pot to expand Onça's EQ. Born for stacking, it's perfect for driving with other overdrives or boosters.



Hot/Cold switch - Bias the JFET sitting in the place of the power tube hot or cold. As in a tube amp, colder will give your more clean headroom, whereas biasing hotter will allow it to saturate more readily.

High pass filter switch - cut low end for extra sparkle, jangly overdrive or to push high frequencies into your amp more like a treble booster.


JFET pair providing true organic overdrive - no clipping diodes emulating overdrive like most OD pedals.

Premium orange drop poly capacitors. These caps have a superior frequency response & make for rich & complex tone.

Panasonic electrolytic caps & high tolerance metal film resistors.

Solid core copper wire which has significantly less capacitance than typical multistrand. This eliminates high frequency loss when bypassed.
