Ahhhhhhhh the old line in rear input
.
Well the first mp1 I bought was a v1 AND I of course did the input Mod successfully albeit with some free styled parts (I used a stagg stereo jack as opposed to a switchcraft).
But I sold this as it sounded like a dead donkey.
Then I bought 3TM, all good in the hood!
Then I went, what da f*ck lets by another MP1 as it's cheap!
So this is the MP1 in question and it whether has the Mod done to it or else it's a V2 as both are usable for guitars and passive pups.I think it might be a V2. I can't remember if it has the switch on top for line level switching on the loop or not.
Anyways I have been going in via the front input. I'll try the rear and see if it makes a difference. My guess is it's noisey, BUT it's also being used with a step down transformer that may not have an actual functioning earth pin.
I'll do the noise by itself test using only MP1
Then test the front and rear inputs.
Then test the earth Pin on the transformer
I did notice that when I moved it from plug outlet that a mixer and whole pile of other stuff was plugged into it reduced the noise a little. Still bad compared to the other pre.
