    Hello, I’m new to the forum. Been building pedals as a hobby for several years. I just built the Ancestral Apparition Reverb from a full kit w/ enclosure I bought from pedalpartsandkits. It works great and sounds awesome however there is a slight but noticeable volume drop when the effect is on. Its enough to bother me. Which resistor(s) (Please specify the R#s on the PCB) need to change to get a slight boost over unity and what value(s) should I try?

    Here’s a link to the build doc: https://guitarpcb.com/wp-content/uploads/2018/06/BD_Ancestral-Apparition.pdf

    Apologies if this has been discussed. I did my best searching the forum.  Thanks in advance for the help!

    If you increase R10 to 20K you will increase the gain from 1 to 2.  You may wish to socket that location and try other values.  Higher resistance will provide greater gain.

    Many thanks! Worked like a charm! 10k was definitely below unity. 20k sounds to be right at unity for me.  Cheers!
