Alright - my MG-800 came in last night and I fired it up through the Eden 210 I'm using for about 10 minutes in between dinner time and the kids' bath times and bedtimes and yada yada yada. It already puts the SWR SM-400 I was using to shame, but that's no surprise. I've got a rehearsal this weekend so I'll get to push it a bit then. Played it for awhile with headphones and my Pawn Shop Mustang bass. It was nice to be able to hear all the notes up and down the neck of the Mustang - with previous combos the bottom 2 strings are huge and the top 2 strings are non-existent.
Anyway - I'm very happy and will report back when I've played it at rehearsal.
Thanks for everything, Jeff. BTW - now that I have a carry bag as well I'll be a walking advert for you. That ought to be interesting
