Title: low impedance to high impedance input does it make noise???
Post by: El Chiguete on February 13, 2016, 04:19:40 PM

Here is one for you tech guys: Does a low impedance signal into a high impedance input does it make noise??? I'm talking about the input of a MP-1.

I've allways had noise problems between my multieffect and my preamp and I was shooting in the dark trying to fix the problem BUT today I found it! I had to turn down the level comming back from the preamp to the multieffects unit internally too not just with the knob on the back... so now I'm in tone heaven!

Ahh, you've refined your gain structure  :thumb-up:
