Hello. I make twice the layout of sabro and it doesn’t work the effect , only buffered and little distorted my signal ,, for 2n4125 I use 2n3906 and the jfets maybe it’s not matched but it”s not this the problem ,,, my signal pass with bass and when I adjust the trimmer the signal buffered so much .. I try to change the 2n5952 with j201 .. but do it the same . I check the links the everything on board 4-5 times
