Magma

The Magma delivers analog metal distortion with three distinct voicing options, powerful 3-band EQ, and Thorn's signature Damping control addressing modern high-gain requirements. Variable metal distortion ranges from aggressive rhythm tones to saturated lead sustain. Adjustable noise gate with On/Off switch controls hiss and hum when playing at extreme gain settings—critical for high-gain metal where noise between notes undermines tight palm-muted riffing.

Controls include Gain, Damping (filters low frequencies preventing mud and maintaining tight bass response essential for metal), Headroom (adjusts clipping threshold for different saturation characters), Volume, and 3-band EQ (Bass/Mid/Treble). Parametric Mid Freq control adjusts midrange between 300Hz-2kHz, targeting the frequency range where guitars cut through dense metal mixes or sit back in the mix. Operates with tube and solid-state amplifiers, full potential at 18V (increased headroom for more aggressive palm-muting clarity).
