A simple Relay Bypass

i'm guessing there isn't an equivalent of a CD40106 with less inverters in it in a smaller package? say, a 3x in a DIP-8 or even a dual in a DIP-6?
 
also, i'm sure this has been covered extensively elsewhere (so please feel free to just drop a link), but what is the advantage of using a relay over, say, a CD4053?
 
CD4053 is not a perfect switch. One has to consider on-resistance, off isolation, linearity, crosstalk and charge injection. They can and have been used successfully when applied correctly. They are more reliable than relays, although a relay does not significantly impact the reliability of a guitar pedal. Analog switches require more parts than a relay solution because they do not support true bypass. What Boss & Ibanez do with JFET switches could be done with a CD4053 or another CMOS switch.

In theory, yes. And it might work in some cases. Do you ever wonder why Boss & Ibanez put buffers before and after their FET switches?

i remember reading about that on electric druid's page about designing a tubescreamer-style overdrive pedal, but re-reading it now all it really says is that the FET switches need isolating from the outside world. doesn't go into details.

i think the little SPDT diagrams on the CD4053 circuit i posted above also made me forget that they're FET switches rather than physical ones.
