Noise and feedback

[rickeb1]

Hey Richard, good point about the using the guitar volume pots.  For all my life, I've always run with the pots on 10, backing down occasionally to get a slightly cleaner sound.  But with the MP-2, lowering the guitar volume seems to have a different effect, in that not much gain is lost, but the character changes a bit.  I noticed that for the first time, I can lower the guitar volume and still really enjoy my lead tones.  I need to spend more time with the unit!

If you are standing close to the MP2 with your guitar, the preamp tubes will cause humming and interference with your guitar pickups. Generally, you can get rid of the noise by stepping back a few steps from any tube driven device :).

It's not the tubes that cause this but the transformers.They emit a 50Hz (or 60Hz) magnetic field that is picked up by the PU's.
