I'd rank the Maz Sr. 38 w/reverb I played a couple of years back at a local "Voxy amp shootout" to be among the best sounding amps I've played in my life. Very loud and it can get that Vox "crushed glass" tone as well as much more. It might work well for jam band music with single coils.
I was glad to see, when I opened your email, that you were not discussing the EZG50. I owned one for 6 months and sold it. People are all over the map on this one but I didn't like it. It was too bassy even with the bass control on zero and lacked the signature Fender sparkly highs we know and love, at least for me. I sold it.
