Buffer

[anti-idiot]

this is maybe, a lame question. i now when using FET-Switching (Flip-flop) a buffer is needed. but what if im using CMOS (CD4066)? do i need a buffer?
cos i'm making this wah w/boost (ala Dimebag Wah) and i dont see any reason to put a buffer on it. any comments?

oh c'mon, nobody?

  This is a CMOS Opamp, Mosfet...it probably has high input impedance to begin with, a buffer may not be an improvement there, but a buffer is just a few buxx on a chunk 'o perf, you could test it, then use it on...whatever you choose to use it on later.

Sometimes you need to wait longer than 8 hours for a reply.

No buffer required.

Sorry, Pete.  A 4066 is a quad bi-lateral switch.

I guess the question is... Does the 4066 in question have a "B" suffix at the end of its part number?  As ToneGod states B= buffer.

The 4066 is a little different from standard logic chips because it's made for switching rather than logic so you will only find parts with the B at the end. No UB version exists.
