Almost impossible to get really valuable info without the other side of the board.

I've used them in some builds and not noticed any issues. But then again, I can't hear mojo worth a damn! :lol:

I think it's a reference to the caps.

I think they are an acceptable solution for supply decoupling, but I do not recommend them for use as coupling capacitors where signal is present.

Damn, that's a pretty negative thing to say about a film cap. :lol:

Does anyone else share Mr. Deville's negative opinion of the MMK film caps?
I use greenies for some less common values so I probably would never notice the difference.

Yep. According to JHS's site it's a modified Bluesbreaker:
"The Morning Glory is a very transparent tone-shaping tool that is the result of several years of building, gigging, tweaking and improving on the original Marshal Bluesbreaker design."

Is there a technical description on why the MMK type cap are not so good? I'm only a noob but I've used them in a few builds with no issues. My main point being I got about 100pcs for cheap and If their prone to failure or generally problematic I'd like to know. No financial loss for me but I'd rather not have to fix an otherwise good build if I can help it. I use them for signal caps :D in 9 volt transistor based circuits. Thanks for any info.

I wish I had one to fully trace, but someone I know who has a double barrel (but lives states away from me) was kind enough to let me know that the opamp is a LM833N.
