Got a chance to crank it.
Definitely much lower noise than before the noise mod and the highs are clear as a bell


My mids are really scooped though and it looks like C32 is soldered correctly.
I have the mid eq up to 10 now when I never had it past 4
It might just be that my caps were really really bad or maybe my ears now want more mids.

If I were to do the 3.666 eq mod for the mids, since I just want more range (higher settings) in the mids and I do not want to change the bandpass range, can I get away with just replacing R151 with a trimpot?

The trimpot seems to control the voltage after the op amp and it does not appear to change the bandpass filter range and I really don't want to calculate the cutoffs.

I know I could add an eq pedal or rack after the eq into the send/receive jacks but trying to prevent more stuff.

Yes changing R151 should do the trick.

Well....I owe some apologies.

Just discovered that the EQ on my G Major was turned on and it was cutting the mids, so it wasn't the MP-1 after all.
Good news for me is I now like to crank the MP-1 mids and then later in the signal chain cut them with the G Major EQ - very different EQ bands of course.

Sorry all.

The hardest thing I found with MP1/2 and associated kit is when to stop, I'm happy, that's my sound, they are so versatile  >:D
