That's such a great story. Way to go. I would have been shaking too, and I play out a lot. I've just never gone solo. You got cajones.

Some of the solo guys I've seen over here use a small PA and modelers. 2 1x12 or 1x15 cabinets with horns on stands and an all in one PA head. You can probably score all that for what you can get out of the Delta. Don't sell it cheap. Those are worthy amphs. All you'd need is a 'character' pedal or your ME50 along with your looper and you should be good to go. Better fidelity. You could even go compact with the PA head and one cabinet, or better yet a keyboard amp. Those will handle the wide frequency range you need.

Good on ya mate.
