Loss of volume with true-bypass

[ttist25]

Hello!

I just boxed up my first pedal.  It's a DOD250-ish distortion pedal.  I did the offboard wiring ala Gaussmarkov's tutorial http://gaussmarkov.net/wordpress/thoughts/wiring-up-a-1590b/

Everything is working great except that when I switch the pedal off, there's a big volume drop.  I know the pedal boosts the signal but I was thinking the volume with the pedal switched off should be similar to the volume with the guitar plugged directly into the amp. 

Any thoughts?  Thanks in advance!

Post some good images of your build.

Another set (or 100) of eyes is often useful in spotting potential problem areas.

it must be similar, or something is seriously wrong. "true bypass" is basically the practical equivalent to being invisible. if you're losing volume, it's because you're losing signal. you have double-checked that bypass is actually quieter than plugged into the amp directly, yes? do you have a A/B pedal?
