In the picture I uploaded I've circled some 1uf caps. 1
1 - Can anyone identiy what kind of 1uf caps these are (my guess silver mica?)
2 - Can I sub them with 1uf multi layer ceramic caps?
I don't have a schematic for this
Maybe give me best and worst case scenarios using mlcc caps in place of
I do have 1uf film box caps but they're huge and I stupidly didn't make a lot of space for them.

Thank you for any advice I'm so close to finishing this one up and this is the (fingers crossed) last hurdle to jump.

The caps you circled look like MLCCs. For the 1 uF variety they are usually X7R rated not the C0G/NP0. For audio signal C0G/NP0 are preferred. You will often see 1 uF X7Rs used in power sections, which is fine. I have goofed a layout before and had to order C0G/NP0 1 uF caps, they exist, but are very expensive.

I'm not sure from you post what you are trying to do. Is this a repair?

last question cause its the last thing I gotta wire up. If I didn't want to use the expression pedal option do I leave it alone ? (the solder pads for the expression pedal) or
Do I put a link in there to jump the tip and ring solder pads?
