Hey everyone. So my Vox V847-A is very scratchy and I can't afford a new wah pedal at the moment so I've decided to replace the pot. Only problem is to buy a new pot is $60 here in Canada. Is there a better online source for my needs? Also are there any simple videos or steps I could follow in replacing it?

I know I could look online myself but I would very much prefer to hear from someone who knows about this topic before. Thank you.
