I built the Ceres and although it outputs sound and seems to sound like it should, the volume is half of the unmodified signal.  I traced the. Signal and it appears the signal drops in strength around Q4 or Q5. (I attached the build .pdf file with schematic).  I have been working through verifying parts and so far so good.  I am not experienced with how the JFETs operate.  Any help is  appreciated.
