i am designing an instrument where i need a preamplifier stage for a guitar pickup, with an arduino controlled CMOS switch that can flip the phase of the buffered/amplified signal.
the switch needs to be a CMOS (i'm using a 4066) for various reasons - so i came up with this circuit combining ideas i found on the internet... it uses both channels of a TL072 IC.
will this design be able to do what i want it to do? i'd love to hear your thoughts on the idea!
thanks for your help,
