Dan Armstrong Black Reaper
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 (Kent Armstrong Pickups), this is an ideal box for both amateur and professional musicians.
