Ashdown Jmy-dd
Ashdown · pedal
The Ashdown JMY-DD is the John Myung signature Double Drive bass distortion pedal. A dual-channel design combines two independent distortion circuits: Drive 1 delivers subtle overdrive with Gain, Loud, and Tone controls for mild-to-moderate growl, while Drive 2 provides vintage fuzz ranging from warm growl to aggressive saturation. The two channels overlap to push into higher gain levels than either achieves alone. Dual VU meters monitor input and output in real time. Rugged Zintec steel construction with LED indicators per channel. Developed in collaboration with Dream Theater bassist John Myung.
