Sho Bud S-15

All the faders are broken off where the knobs push on. Anyone know where such faders can be found? I'm guessing this gonna have to be converted to new parts, but figured maybe there's someone out there that makes parts for these amps.

Here's a post with the same amp and same issue: The Steel Guitar Forum :: View topic - Sho-Bud S-15 $350

I may just suggest the customer use a pick or screwdriver to adjust faders, assuming that if they're sprayed they'll stop scratching.

Those pictures don't help, we need a photo of the slider itself.

The motion range is 45mm 60mm 100mm some other mm? The sliders are hard wired or soldered to a circuit board? The value needed is? Do they mount to the panel or to a sub-structure? Or to a board?

If your shafts are broken off but they sliders all work, we only need to find similar new sliders and steal the slider part from them.

I am sure we can come up with appropriate looking slider knobs.

Ok here are some pics of the faders. They are all mounted to a metal panel, then that panel is mounted to the chassis.

Body length: 2+15/16"
Slider length: 2.5"
Mounting tabs: 1+9/16"

Values:
Volume 10k
Treble 100k
Mid 10k
Bass 100k
Reverb 10k

Those look like the old CTS slide pots. I used to see them on the surplus market all the time. You may be able to find some and then do as Enzo suggested just steal the plastic wipers out of them and reuse the original carbon elements.

I'll dig through my old stuff and see if I have any of them in the parts drawers.

OK, so they'd be 60mm sliders (the travel). But that whole upside down thing is a killer. The slot is in the resistive element strip? Geez. Someone may have them, but I've never seen them.

The people at Sho-Bud might know where people are getting replacments, can't hurt to ask.

Were it mine, I'd likely ditch the whole assembly, and make up a new one from metal strip, similar to what is inside an Acoustic 270 or something. The sliders do not need to fit onto a circuit board, so you have room to be creative.

Thanks guys. Enzo where would you source the faders from?

[Enzo]

Mouser has a selection.

Finished this up. Came out good....2 faders weren't what the pic showed on mouser....but alas I shoulda checked the datasheet as those pics can be inaccurate. Those 2 faders dont require knobs. The pin-outs took a little trial and error to get them to work correctly. Had to use silicone to set them on the mounting board so I could fanagle em into position from the outside front panel. Then let em sit overnight to dry in place. In the end it is fixed and the customer doesn't need to use a pick or screwdriver anymore.
