So, about a year ago I bought a Nano Small Stone from a friend of mine, and it worked great up untill now, now when i turn it on I get a MASSIVE volume drop. The sound is barely audible even with my amp cranked. Whats weird is that sometimes it works normally but most of the time i get a volume drop. Since i didn't buy the pedal new from the shop I don't have the warranty, so does anybody have any idea how to fix this? I'm comfortable with taking the pedal apart and doing some soldering if i have too. Thanks.
Have you checked the battery???
i use a power supply, and that's not the problem because I get the same thing with a new battery as well.
You should open the pedal up to check if you've got wires crossing anywhere near the power input or switch.
it's a PCB so there aren't any wires to be crossed, except for the one for the battery which has it's contacts taped off.
