Description

The “2112” Dual Combo combines two iconic circuits to capture the legendary sound of RUSH’s early years. This Combo features the “Phaser” and “Plexamp” circuits, designed to work in perfect harmony to recreate the early tones of Alex Lifeson in RUSH.

The Phaser combines elements from several iconic designs, it achieves smooth transitions between phase shifts, enhancing modulation for an organic tone. The Phaser offers precise control over Rate, Intensity, Volume, and Voice, allowing you to fine-tune your sound like never before. Enjoy reduced noise levels for a cleaner audio experience.

The “Plexamp” circuit serves as a quality Marshall amplifier tone with excellent tone shaping controls. Going a step further, this circuit when used in tandem easily replicates many 70s sounds then reverse the order for an entirely different set of useful tones.

Key Feature:

• Built-in order switching for endless tonal possibilities, to easily reverse the signal path. Use a “Stubby” or short bat switch.

Easily achieve the early tones of RUSH, Thin Lizzy, Joe Walsh, Lynyrd Skynyrd & more.

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

LDR Phaser sets are also available!

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