Circuit Bent Modified Commodore 64 Computer

With Cynthcart SID Chip Synthesizer

I've modified many Commodore 64 and 64c

computers over the years. The mods I add are

1'4" input which allows you to run external sources thru the filter. 1/4" and RCA output  jack with volume control for easy connection to your amp, pa, etc. RCA baseband video jack for quick connection to your monitor. Two control knobs, one is used to sweep the filter and the other can be assigned to a number of features when using the Cynthcart, like lfo, pitch, etc. 

Atariage.com stocks the amazing Cynthcart

that utilizes the C64's SID chip for some fantastic synth sounds which gives It some  really fat bass.
