I've got a signal coming from an electric guitar and I need to switch it. Basically it's a distortion circuit. I need to switch between the distortion and clean (directly connected to the output)
My first approach was to use a DPDT switch but I have none at home, they are a bit expensive at my local shop and I haven't got a lot of money for the moment (around 8€/10$ for the cheapest one).
Then I took a look at what I have in stock and I found a cheap solution, a simple momentary switch, an ATTiny45, a 4066 quad bilateral switch and some caps and resistance. Basically the ATTiny45 read the switch and control the 4066. Even if I had to buy them, the sum for these components is cheapest than the price of a single DPDT switch. I've tested this solution and it seems to work fine from an ear point of view. And I've got no switching noise, which I suspect I would have with the DPDT solution.
So my question is, do you see any technical advantages for the DPDT or disadvantage for the "logic" solution regarding the application I've described ?
