Hi I built this great pedal (schematic from GGG) and it sound really powerfull !
Anyway it sound too dark for my personal taste... even with tone pot regulated to max
Is there a easy way to get it more middle-high centered without loosing overall character ?
It is already soldered on borad... so not easy to experiment other solutions,
I really appreciate any suggestion !
Thanks in advance.

It always depends on the rig.
The R17-C13-R18-C14 part is a 2nd order RC LPF having the corner frequency around 720Hz (remember where else did you see this value?) and the slope around 40dB/decade. This means it is pretty effective at removing the treble content.
It seems your rig is not so bright, so you could try removing R18 and C14 and connecting pin 1 of the Volume pot to R17 and C13. Or you could remove the whole LPF altogether, then connect the Volume pot directly to the Tone pot (or better through a buffer, but it should work anyway).
