I also have a 400RB and still I'm drooling in anticipation!![]()
Same here, it's a perfect solution for my needs. I suspect I wouldn't use it as much in playing through my rig only, but that boost footswitch could sure come in handy. Same with the FX loop.
The tuner is a great plus for me IF it's accurate as, say, a polytune 2. That would save me having to bring DI said tuner, so that's one less thing to plug in.
The aux in/out are a nice plus, and I was always interested in using MIDI with my bass...
I just hope this is sensibly priced.
