From Modest Mike’s Mods 
This listing is for mod service. You send us your pedal, we perform the mod service and send your pedal back to you.
We modify your pedal to give it a fuller sound, better tone, and more available gain
We also replace the LED with a bright blue water clear LED. It's clear when the effects are off, and a bright blue when the effect is switched on.
If your model is the older one, we convert it from 12V ACA to standard 9V PSA like most other pedals.
Boss started using tiny, surface mount parts in their pedals a few years ago. I can't modify those.
But if yours looks something like this inside, then we are good to go:)

Simply purchase the mod service, and then here is a 3 point check list:
1) We will be performing our mod service on your Boss DF-2.
2) Please include your return address, and any special information about your mod, on a piece of paper inside the package you will be sending us.
3) Just before sending, please recheck steps 1 and 2.
Please send your pedal to:

21 Nottingham DR
Bella Vista, AR 72715
The turnaround time is 3 business days or less.
Thanks for your business!
Mike
