My SWR 500 has an internal ground loop problem that I can’t seem to figure out, so I decided it may finally be time to replace it. The cabs I’m currently using are the Mark Bass 2x10 and 115 travelers. I was considering the Mesa Boogie d800 plus but read somewhere that it didn’t play nice with mixed Mark Bass cabs (not sure if this is a fact). I play in modern country/80s bands and use a 5-string bass. Any suggestions would be appreciated.
