Hi, everyone. This is my first post here. :)
I just tried my hands with adding more bass to my BOSS OD-2. All went well with replace with replacing 3 caps and the pedal now has a better bass response. But in the process, it seems to have lost some of the output volume (and maybe a touch of available gain but not really sure on that). Would someone make a couple of suggestions to get the volume back up? Below is a link to the schematic. What I did was to replace C1, C31 and C5 with bigger value caps (.1uF).

Changing c35 to a .22uf will get you more bass without a volume drop, or distortion drop.
Take care,
Brian
Thanks, Brian!
