PT-80 Delay - Volume Issue

[jcbak]

I'm a beginner at this.  Built a couple of pedals.  Put together a GGG PT-80 Delay.  Everything works fine with the exception that there is a slight drop in volume when the pedal is engaged.  As per a previous suggestion on this forum, I increased the value of a resistor but there is no change.  I would like to add a trim pot inside but since the PCB has no provision for it, I'm totally lost as to how to wire it.  Any suggestions are welcome.  Thanks.
