The Bi-Onyx modifies the original Onyx circuit which offered completely independent clean and lead controls, as the name suggests this instead amp offers Dual channels with independent clean and lead sections including EQ, Gain, Master, Reverb, Contour – and the newest feature, the Volume Boost. The Volume Boost increases the volume without affecting the gain section, to put it simply without adding more gain which is often the case. The foot switch controls the channel selection and allows you to add the volume boost to each channel. The Bi-Onyx ships with EL34 Power Tubes but you can use 6L6 tubes, just flick a switch on the rear panel and re-bias.
The head will be available in 50 Watt and 100 Watt versions both with Analog spring reverb.
