Boss rc 505 /mkii PARTS for repair 😭

hi, Ill be as short as I can be

I have a boss RC 505 and an MK2, both need repairs the RC 505 is in worse condition. All of the Fader knobs have broken off..

I went through the process of finding a certified location for boss repairs for them to tell me that they reached out to boss for the parts that they need to be informed that those parts for both pedals have been discontinued so they could not repair it

Now (being that this is my job) I’m on a mission to do my best to find those components and see what I can do.

does anyone know about places to get secondhand parts and are use/broken/inexpensive boss RC 505 that can be torn apart for parts. Any like suppliers of the individual components that would be a great help because I am running short on ideas.

i’m lookingfor s knob 05010723, part 5100006672

any thoughts would be great. really not trying to buy 2 entirely new pedals that’s insane if i can dodge that

Aliexpress have loads of replacement parts. Not necessarily Boss original, but a set will fool most people. I saw these, but if it’s not the right size, another seller will have something very close.

this is super cool i’ll look into this thank u. i guess the tough part is i can’t actually find the dimensions specs anywhere. these look like they’ll work though

any ideas about the slider metal rods?
