+## Sliders?
+
+This won't be easy; need both A1M (x3) and B10K (x1) sliders in the same form factor, with maybe a little wiggle room on the footprint.  Some options:
+
+* Bourns PTL series, such as:
+** https://www.mouser.com/ProductDetail/Bourns/PTL30-15O0-105A2?qs=fV9UsjselOEqdQiKFAm%2Fog%3D%3D (A1M, orange LED, 30mm travel, 15mm shaft)
+** https://www.mouser.com/ProductDetail/Bourns/PTL30-15R0-103B1?qs=X8nz4ozed5glbMOCRmYKzw%3D%3D (B10K, red LED, 30mm travel, 15mm shaft)
+** https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15R0-103B1/3781301 (red B10K) and https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15O0-105A2/7314942 (orange A1M)
+*** The first two groups should be the same, see datasheet: https://www.mouser.com/datasheet/2/54/PTL-777483.pdf (page 4) if we want them to match.  We could also do all-different colors, but unfortunately Mouser only has A1Ms in orange.
+*** Expensive, about $3 each.
+*** Replacing LEDs in these is supposed to be possible without disassembly of the entire pot.  
+* BI/TT PS series, https://www.mouser.com/datasheet/2/54/PTL-777483.pdf
+** Would need another supplier, mouser sells only in 1000+ for these.
