Does this mean IC6 is the clock?
IC9 is a digital reverb engine chip BD3201-14a http://www.bdnc.com/datasheet/bd3201-14A_spec_V1.6.pdfIC6 is a CS4340 is a D/A converter http://pdf1.alldatasheet.com/datasheet-pdf/view/58109/CIRRUS/CS4340.htmlIC7 ia a CS5340 A/D converterhttp://pdf1.alldatasheet.com/datasheet-pdf/view/115334/CIRRUS/CS5340-CZZ.htmlThe other 3 chips are ST microelectronic EF797 dual op amps.There is no clock chip , the main processor takes care of all that.
What is the most likely culprit with it apparently being a conventional 3PDT switch based true bypass pedal?
I would start by making sure that the 3.3V regulator is functioning as this is what the processor, D/A, and A/D are powered by.If it is anything like the FV-1, it REALLY, REALLY needs that voltage to be AT LEAST 3.3V to work well.
