1847, It's a nice sounding amp for sure. Wish he had of said what element was in his mic, and tried a few different kinds. Be nice to see Cliffy demo this amp.
the trouble with recording you tube video's with your phone is a lot of the subtleties are lost, you can get an idea how things sound,
you can not hear "just how good this amp sounds" from this video.
it also makes it hard to discern between mic's. here it sounds to me like a crystal.
the other issue with you tube is....
if you go to the trouble of recording in high def, it still gets compressed then people will use lap top speakers to listen to the playback, defeating the whole effort. if you choose to record in higher definition people will have a choice to listen on better speakers, but it will still lose a certain quality when uploaded.
you really can't go wrong with a crystal mic and a supro amp. you can plug straight in no effects are needed. they also offer a matching ext. cab. very very cool indeed. they hold their own against "anything" available.
