TREMBLE

self modulating potentiometer replacement

click image to view larger

price: $34 ::: SOLD OUT

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

the tremble is another potentiometer replacement but this one is both squarewave and switchable to pseudo-random slightly controllable chaos with a starve feature. it is a wide range variable squarewave LFO with 3 more LFOs on board that have a fixed rate and they are used to make the pseudo-random result. 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 tremble 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 there for more control. vactrols by nature are not perfect 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 800k / 900k and this is adjustable over a 3M range using the depth pot. which means you can choose to modulate 0k to 800k or sweep the depth pot and modulate the 2.2M to 3M range. also using different voltage power supplies will increase or decrease the resistance range respectively. so please take that into account. 9v recommended.
