Octarock diodes

I am working on building an Octarock and I'm up to diodes. The BOM calls for BAT41 but the board is printed BAT46. I bought Bat41, will they work? Also the BOM has 2x 2N5457 but the board is printed with just one and one MPSA13, can I use 2N5457 for both?

Nevermind for the 2N5457, I see the second one now. I did purchase MPSA12 instead of 13 will that work I should I get a replacement?
 
BAT41 will work fine, I've used both (as well as 1N5817 and 1N4148).

Q3 is an emitter follower, MPSA12 should work perfectly fine.

Thanks! The BOM also calls for 2x On-On SPDTs but it looks like one should be a DPDT. Is that right?
 
I haven't done a full trace, and I'm going off memory, but hopefully this helps.
For the Sub Bat41/ 46, either will work.
Same for the Octup diodes, though I like 1n5817s for their lower vf in that position. (Search for my Octuplet build report to see how they sound)

Clipping diodes can be whatever- that section is basically a Tube Screamer and runs only to the octave up section. I left mine stock in both Octarocks and Octuplet
