SHIVER

self modulating potentiometer replacement

click image to view larger

price: $29 ::: SOLD OUT

::: DESCRIPTION :::::::::::::::::::::::::::::::::::::::::::::::::::::

the shiver is a slightly simpler version of the quiver with a slightly different range. it is another self modulating potentiometer replacement, but it has a variable shape between triangle and sine. the LFO feeds the LED side of a vactrol and the variable resistor side of the vactrol is available to you via two holes on the board. you can attach the variable resistor pins to any place you would normally use two pins of a pot and use the shiver to modulate the resistance. i also included a section on the board for you to insert an additional limiting resistor for applications where the full range will be overkill, if you like you could also use a pot for more control. vactrols by nature are not perfectly matched so they will vary from device to device by small amounts. on average when using a 9V power source the general resistance sweep is between 0k to 50k / 60k and this is adjustable over a 0k to 200k / 300k range using the depth pot. which means you can choose to modulate 0k to 60k or sweep the depth pot and modulate the 240k to 300k range. also using different voltage power supplies will increase or decrease the resistance range respectively. so please take that into account. 9v recommended.
