The high gain tube amplifier JOYO Mjolnir is specially designed for metallic sounds. It presents a direct approach with a serious and serious distortion. This amplifier will give a thunder roar to the two-coil pickups and will make single coils cut straight through the mix! The JMA-15 is designed with a conventional high gain circuit and two channels: Channel 1 is CLEAN, PUSH is used to boost the average frequency and gain. Channel 2 is a distortion and includes the NORMAL and MID CUT controls. In NORMAL mode, you can get a ferocious modern distortion. Engaging the MID CUT will give you a low solid and heavy frequency. BOOST can be used on both channels. The JMA-15 has 4-8 and 16O impedance speaker outputs that can power any consumer cabinet. An effects loop is included, but can be BYPASSED when a pure tube tone is desired. Channel switching is easily accessible during execution by the foot switch. The JMA-15 is housed in an all-metal case, and is powered by three ECC83s, one ECC82, two EL84s. 15W output, can be used for practice, repetition and performance. 15 Watts Double Channel Guitar Amp Tube
