Tone Controls

The Tilt Control kit consists of a small PCB (1.4in by 2.8in), a stereo, shorting, five-position rotary switch, eight capacitors and sixteen resistors. It is a passive design, which entails a -3dB insertion losses and whose center frequency is 500Hz and its nominal input impedance is 100k. The center position results in a flat frequency response, but is down -3dB. As the control twists clockwise, the highs go up by +1.5dB per click and the lows go down by -1.5dB per click. Conversely, as the control twists counterclockwise, the lows go up by +1.5dB per click and the highs go down by -1.5dB per click. Kit includes user guide and the PCB, rotary switch, and all the polypropylene capacitors and 1% metal-film resistors.

The Tilt-2 Control kit consists of a small PCB (1.4in by 2.8in), a stereo, shorting, three-position rotary switch, four capacitors and sixteen resistors. It is a passive design, which entails a -2dB insertion loss and whose center frequency is 600Hz. The center position results in a flat frequency response, but is down -2dB. As the control twists clockwise, the highs go up by +1dB and the lows go down by -1dB per click. Conversely, as the control twists counterclockwise, the lows go up by +1dB and the highs go down by -1dB. Kit includes user guide and the PCB, rotary switch, and all the polypropylene capacitors and 1% metal-film resistors.
