Fernando,

Please see this: http://www.madbeanpedals.com/forum/index.php?topic=902.0
And tell us a bit more (any parts subbed, voltages, etc) and/or provide a pic of your build/wiring.

OK!
I've solved the problem with another Fet and a correct T1 voltage bias.
I've done a wrong voltage adjust of the T1 Fet with my DMM (beginner problem i think)
Thanks.
Fernando
