Sounds like a good choice. That SD hums a little bit when is sit next to electrical stuff but I us a Shure wireless pac and move around until I don't hear the buzz. I grounded and shielded real well so the buzz isn't that bad. I purchased an inexpensive 5 string about 6 months ago and really like it. It takes a few minutes for my brain to compute from 4 string to 5 string.
