Description

NostalgiTone ZOSO Tone Dual Combo: Introducing a powerful fusion of two iconic circuits designed to recreate the legendary sound of Led Zeppelin. The “WattAMP” circuit delivers robust, high-headroom clarity reminiscent of Hiwatt amps, providing rich overdrive tones without excessive volume. Meanwhile, the “Luna Fuzz” offers a thick, substantial fuzz tone, allowing you to explore a wide range from tight overdrive to ultra-saturated fuzz. Experience the unmistakable tones that defined an era and unlock endless sonic possibilities!

Key Features:

• Authentic HiWatt-style preamp and tone stack with adjustable EQ for precise tonal control.

• Fuzz is used for soaring solos and powerful riffs, equally effective as a standalone Fuzz tone or in tandem with the Preamp.

• Built-in order switching for endless tonal possibilities, allowing you to easily reverse the signal path.

(Use a 3PDT On/On short shaft / stubby switch for order switching)

Designed for a 1590BB2 enclosure, featuring the same dimensions as a 1590BB but with 125B clearance.
