Hitting random Celtic/Nordic/Folk stuff, Mean Mary came up.
Never herd of her, and banjo normally ain't my preferred, but wow, just wow.
And I just love her voice too. Matter of fact, everything about her. What a gal.. :-*

Two studio engineers are discussing singers who can't keep correct pitch to the pont they can't really sing.
One says, "sure, the Mellotron and various software may fix pitch problems, but you just can't polish a turd."
The other quickly responds, "oh, but you can. Recording engineers do it every day."

Don't think the R17 will work. Was this unit a V1 or V2?

It's a V2.

Well this is quite a strange solution for this. The MP-1 also has a FET input buffer. Now a low pass filter won't help because you can hear the frequency, so you can't filter that out else you get a gap in the audible frequency range. I think it's more of a phase issue and acoustic feedback together with some capacitive or inductive stuff that is going on in the cable. Using a buffer makes everything low impedance between the guitar and the MP-1, this way you get another phase/frequency plot.


This describes an incredibly bad luck!  :lol:

So, do you still think that putting a 560K resistor in R17 would be an attempt that worth a try?
Or can it be something that went wrong with the FET input buffer in the MP-1, after mods?

I did the test with 2 different buffered pedals and it works the same way.
Now I'm about to buy a TC Electronic pure buffer and see what happens.
