Boss FS-6 Power Adapter Mod
But why?
I own a Boss FS-6 footswitch I cheaply bougth from eBay a while back and use it with my Boss RC-3 Loop Station. What annoys a lot is the fact it can only used with a battery.
It wouldn't be a big deal if it where possible to turn ir off without disconnection the TRS or both TS jacks. So I decided to modify it for the use a standard 9V power plug.
It's fairly simple, just open the case (unscrew the four screws on the bottom an all three nut screws on the back and slide it open). Drill a hole for a small DC power jack and solder it to the battery pads.
I additionally put a diode in between the original battery plug an the battery pad, just in case someone (inluding me) forgets it has a battery in in and connects a power supply.
A better way to do that would be the use of a switching DC jack, but I haven't found one which is small enough.
