Awesome Amp but beware!!

Ok First off I bought this Amp before it even shipped, and Peavey kept Pushing the Shipping forward, so mine is first production so i don't know if that is why i had a few Problems starting off.+++Let me say that this Amp does sound great and I have gotten Many compliments on my live sound in both my Heavy Rock and Blues Band+++ BUT BE WARNED!! You will need to Purchase a Voltage Regulator to be Glich free and Confident your Amp doesn't have to be reset(Remember you are dealing with a Full Computer Here so Sometimes it ACTS like a Computer,for instance a Trick I have learned was don't plug your Guitar in before Booting/Warming up because just like a computer it acts like an Outside USB item and sometimes doesn't boot properly, so give it about 3-minutes to have it warm up and boot up) Now the Voltage issue has been an Issue at 2 BIG gigs of Mine , one thing that Technically happens is If Voltage is Low in a Venue then The Tubes Take Priority, so scratch trying to Switch Preset's or anything the Sampera Pedal can do for you(Very frustrating in a live situation!) so if the Price seems too good to be true this is why ,now I have to spend as Much on a Voltage Regulator(Furman 1815 R p i think?)as the Actual Head, now trade that for some truly amazing sounding unique Tube sounds i get with minimal Setup time and the only Tube based Modeling amp with ANALOG distortion instead of Digital and you do have quite an amazing amp, but 2 more Suggestions for Peavey for the Future, Either put an XLR as well as the USB port for output so you can use the output live without turning off the Head like the headphone jack,and make a seperate Volume for the Loop,Oh and it does NOT play well with others so if you think you can Daisy chain it or use it in Conjuction with other amps OR use outside EFX Forget it! Fully self contained!
