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 4

The industry standard for years, the Type 4 is still manufactured today using Hammond’s 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.


PART NUMBERING SYSTEM
Reverb part numbers consist of a seven digit code.
EXAMPLE: 4EB2C1B
Each digit in the part number represents a specification. The parameters are as follows:

1ST DIGIT = REVERB TYPE
2ND DIGIT = INPUT IMPEDANCE
3RD DIGIT = OUTPUT IMPEDANCE
4TH DIGIT = DECAY
5TH DIGIT = CONNECTORS
6TH DIGIT = LOCKING DEVICES
7TH DIGIT = MOUNTING PLANE
