Since I can find no clips on line of the new ET-90 I would post this here.
I have had a Vet -30, Retro-30 the stock Zinky labled Eminece as well as a Clestion G12 H 30 watt in the amp at some point. I had settled on the Retro-30 and then used the one I had in the Zinky for my Blackstar 1/12 that many times I will run offstage miced. I was about to order another Retro but talked to several at WGS on the ET 65 but they recomended the 90 for what I was doing so I decided to give it a try.
I am absolutely satisfied with that choice and my Zinky has never sounded better on stage. This clip is from a Worship service I recorded with a Alessis Video Track and my amp is unmiced here. The tone killed all night and my amp has never sounded better THANKS GUYS!!
