  • New Gundry Filter circuit available!

    We can install this circuit on just about any preamp. Originally designed for Carver Sonic Holography, this filter can be incorporated into many kinds of audio signal processing or media sources. The filter can be turned on or off by a jumper, or with a switch wired into it.



    The circuit requires +/-12 supplies and space to mount.

    It's function is to attenuate frequencies which our ears are naturally very sensitive too, such as baby crying and sirens. By adjusting the frequency response of some audio processing, such as Sonic Holography, the result is a better sound image, especially at high volume levels where certain mid-range frequencies dominate our ear/brain system and smear our perception of depth and detail in the music.

    Price: $24 (PCB with parts) or $40 installed (in addition to standard service fee).
