Maybe I'm late to the party (it happens a lot I have so much going on). I just read that the Dr.Z Prescription is no longer going to be made. I assume this is because, like everything else in business, it didn't sell as much as the other amps. I had a chance to try one not too long ago and I liked it a lot more than the Maz Jr, which everyone seems to love. The Maz wasn't a bad amp, but I don't think it gave me anything more than my AC15C1. Since I already have the AC15, maybe I was just looking for something different...but I really just liked the Prescription better. The prescription had so much more punch in the bottom and growl...it was just a great amp and was probably going to be the next one I bought. Anyway...I'm sorry to see it go.
