Check the output from the 100K trimmer pot.  For some reason, the layout has the output from the LPB1 going to the wiper.  It will work only if the pot is 100% CCW.  I would just remove the trimmer and send the signal from the 100 nF cap to lug 3 of an external pot (lug 2 = output, lug 1 = ground).
