P.S.S.

After removing 560r resistor , sound is a bit louder , but it's still quiet and most of bass is cut :(

Is the input cap definitely 100n?

yap , should i lower the value of that cap ?

No, I was just guessing if you're lacking bass and level you might have a 1n or 100p cap instead of 100n. Lower values than 100n might affect the frequency, 100n is plenty for full guitar range. That buffer should be unity, it might seem slightly brighter due to the fact you're used to unbuffered long cable runs dulling the treble slightly. A large level drop suggests a wrong value used somewhere, or a fault in the construction.

The first layout asks for a tl071 opamps (single opamp package). If you are building that, using a tl072 (dual opamp package) wont work.
