2 band EQ output Cap question

[Sauerkret]

Hello, do i need to put a capacitor near at the output to provide dc blocking? (value?)
The cirquit will be placed before the parapedal wah.

 If you don't you'll be relying on the next circuit to do DC Blocking.
  10uf should cover guitar and probably bass guitar relevant frequencies.

IF you use true +/- power rails, and low-offset chips, you will have nearly Zero DC out and do not need a cap.

If you re-rig it as +9V and a rail-splitter, you will have 4.5V DC at the output, which would be bad; you need the cap.

But.... if you are not sure, just put the cap in anyway. And if the next stage is a guitarish-kind of input, 0.1uFd is ample. (And avoids trying to figure out which way to put a 10uFd electrolytic.)
