The Black Reaper unit modifies the mid range frequency by decreasing the mid-range level.
They're back! The legendary Dan Armstrong Sound Modifiers are now available again and they're better than ever. These units are now 100% USA made and are hand-built to authentic 1975 Dan Armstrong specifications by Grafton Electronics.
Dan Armstrong Sound Modifiers are a range of simple, compact, and rugged accessories that can be used with any electrified instrument. They are designed to plug directly into the output of a guitar or bass guitar to give the player fingertip control of the sound, but they work just as well plugged into an electric keyboard or the output of any electronic accessory. Any musician, who wishes to use these units at the input of the amplifier, rather than at the instrument, need simply interchange two colour-coded wires inside the box.
All six units are built in a heavy duty aluminium casing, using only the finest quality components available. Overall dimensions are 59mm wide x 59m high x 70mm deep (including plug). The unit only protrudes 43mm from the face of the guitar.
Each unit has a specific effect or function, but several of them can easily be combined by plugging one into another to produce more complex effects. For recessed output jackplates (e.t.c. Strat) adaptors are available to facilitate use.
This is a simple to use unit that can remove higher volume mid range frequencies to give richer full range level out from the instrument. Input Impedance is 80 k Ohms. Output Impedance is 1800 ohms, and the Signal/Noise ratio is a quiet 86 db. Made with a hand wound open choke coil designed by Kent Armstrong, this is an ideal box for both amateur and professional musicians.
Power Source: This unit does not need a battery.
