Products and Specifications
TYPE 4
The industry standard for years, the Type 4 is still manufactured today using Hammonds original design. Four counter wound and coupled springs deliver superior mechanical performance and the classic sound that helped make the Fender Twin Reverb Amps famous. Outer channel dimensions are 16.75 Length x 4.375 Width x 1.313 Height.
TYPE 8
Designed for applications in which the overall sound quality is important and a compact package is required. Small in size, this three spring reverb approaches the rich textural quality of our larger reverb units. Outer channel dimensions are 9.25 Length x 3.375 Width x 1.313 Height.
TYPE 9
Six springs, counter wound, coupled and placed in parallel, combine to create Sound Enhancements fullest, richest reverb effect throughout the full range of musical sound. Ideally suited for keyboard, sound reinforcement and pedal steel applications. Outer channel dimensions are 16.75 Length x 4.375 Width x 1.313 Height.

TYPE 1
A small low cost two spring unit designed for application when price is a major factor. Ideally suited for practice amps. Outer channel dimensions are 9.25 Length x 3.375 Width x 1.313 Height.
(Type 1 is not available at TAD, we recommend to upgrade with equivalent Type 8 model)
