JOYO JMA-15 MJOLNIR 15w Dual Channel Guitar Amplifier Head - Black
JMA-15 MJOLNIR Amplifier
The MJOLNIR is a high gain tube amplifier head that specially designed for creating the ultimate powerful metal tone. It features 2 channels, 3 preamp tubes and 2 power amp tubes. From deep low frequencies, clean mid boosts to fierce modern distortion.
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 Mighty MjolnirBy: Ryan on 1 October 2021This thing is incredible! Could not be happier with the JoYo Mjolnir. Clean channel is AMAZING especially when pushed to edge of break up. Gives absolutely beautiful tube tones. Use the included footswitch and change it to the 2nd channel and have your face melted off with the tonnes of gain it has on tap! Build quality on this amp is top notch as well. It’s built like an absolute tank with its metal body and it feels very solid. Once again. Could not be happier with this amp. Great sounds. Great build quality. Absolute bang for your buck value! If you’re in the market for a lunchbox amp, look no further!
