Hi Guys,
Does anyone have a boss tr2 modded or have done the mod to fix the volume drop by adding a pot?
I just dont know wich resistor i change for the pot, if it's R9 or R19?
Thanks in advance.

I fixed it on mine. I changed out R9 with a 4k7. I actually get a slight
volume increase now. When you play by yourself you can notice it but in
a live setting the increase it not even noticable.
Others have just put a 10k trimmer in place of R9 and just adjust it to get unity volume.

It's not a cheap one!! But it might need some pimping somehow...

The volume drop issue is a good one to perform, and I've seen a noise related one, but can't find it anymore... I have this very pedal, and I've once thought of using it as a housing for a cleaner one...

Anyone on this noise mod?
