JOYO Mjolnir High Gain Tube Amplifier is designed especially for metal sounds. It features a straightforward approach with deep low end and searing distortion. This amplifier will give twin coil pickups a thunderous roar and make single coils cut straight through the mix! The JMA-15 is designed with a classical high gain circuit and two channels: Channel 1 is CLEAN, PUSH is used for boosting middle frequency and gain. Channel 2 is distortion and includes NORMAL and MID CUT controls. When in NORMAL mode you can obtain fierce modern distortion. Engaging the MID CUT will give you a solid and heavy low frequency. BOOST can be used on both channels. The JMA-15 has 4-8-and16Ω impedance speaker outputs, which can power any mainstream cabinet. An effects LOOP is included, but can be BYPASSED when a pure tube tone is desired. Channel switching is easily accessed during performance via the included FOOT SWITCH.The JMA-15 is housed in an all-metal case, and is powered by three ECC83, one ECC82, two EL84. 15W output, can be used for practicing, rehearsal and performance.

Be careful...NOT NEW!
Product was not advertised as used.When I got it home, I tried the clean channel and it worked great. But when I tried the dirty channel, the volume was really loud, even with the knob at minimum value. I turned the potentiometer a few times and I figured the knob was not working properly. Because I have good electronic knowledge, I knew the pot was dirty, but for someone who don't know, they would not be happy. I cleaned the potentiometer with contact cleaner and it worked after. When reassembling the unit, I realised the knobs were not even the same color. I'm a bit disapointed, but at least the amp still works...

Nice Amp / happy wallet !
A good amp with good capabilities for an honnest price. Overdrive/ lead channel sounds nice. Lamps are customizable as well. Or so I heard... I would have liked the addition of a headphone input though.Overall, nice job Joyo!
