For reference, here's our last project. Listen to track four, To the Light...* The hum is there under the guitar intro, and especially at like 1:47... Our songs will often break down in the middle with only quietly strummed guitars barely keeping the beat, and that's where the noise becomes really noticeable.
I like that bari guitar solo. Nice stuff. I posted a similar question today. Bought a new, noisy amp today.
