Good news !!!
I solved the problem, for some reason one of the filter capacitors to ground at pin 7 of the section of the "long delay" was bad, i changed it and now sounds perfect. i don't know if was a bad luck ... but that small capacitor was the problem .....kill me please

Looks like the diode is disconnected from the circuit, i see an unsoldered pin on the bottom right ..
Man that soldering job is NASTY.. I think you should do it again, and get 1mm or thinner drill bits
This diode is disconnected because i made a bridge on the JFET for the effect is always active
and yeah ... i know that soldering it's sucks, but that's because i resoldering many times looking for the problem ... it's kind of pcb test so doesn't bother me it all ejejeej
may also be that the picture not favor much jejej
A lo chilensis: Si en la foto se ve entero penca pero es una prueba asi que no me intereso mucho que se viera bien sino que cumplieran con el objetivo
Saludos !!
Cheers guys !!
