Description Product Description This Two-Rock Bi-Onyx 50 Watt Amplifier Head has a clean channel that produces the luscious clean sounds Two-Rock is known for and a lead channel that offers warm, thick overdriven sounds. The volume boost on both channels will give you that extra edge when you need it. The analog spring reverb is lush, 3-dimensional and easy to control. You can get everything from a subtle one-room effect to soaking wet, deep reverb. There are independent controls for each channel, which simplifies things and makes it much easier to customize your sound. The EL34 power tubes will sound great through whatever cabinet you use. We are an authorized Two-Rock dealer. From Two-Rock: "Designed to give dual channel players a new and greater degree of control, in any performance environment and for any style of music. Featuring independent controls for clean and lead; including EQ, gain, master, reverb, contour and volume boost. Avail in 50W & 100W head options with stock EL34s (optional 6L6s), foot-switchable channel selection and volume boost, a newly designed output transformer that delivers a tighter low-end and a broader range of highs and mids, and a new speaker output feature that enables multiple cabs to be in use at the same time."
