Ashdown MAS Vintage-Fuzz
Ashdown · pedal
The Ashdown MAS Vintage Fuzz is a germanium-voiced bass fuzz pedal from Ashdowns Pro-FX signature pedal line. It delivers warm, rounded fuzz tones with the characteristic softness and touch sensitivity of germanium transistor circuits. Designed primarily for bass guitar, it preserves low-end body while adding organic harmonic saturation. The vintage germanium voicing suits classic rock, soul, funk, and early heavy rock bass tones. It is a member of the same Pro-FX Vintage Fuzz family as the standard Ashdown Vintage Fuzz, offering the same core circuit in an alternate product configuration.
