You sure? The splawn rep is telling everyone its the nitro. If so. the guitars sound scratching and shitty to me which would make me not buy that amp. thats why I thought it was a digital box. I dont have the cd either just going off of the streams i heard which could be why they sound bad to me. they have that scratchy highend that you get sometimes with the digital boxes and low bandwidth sites.that is why I was asking what the amps were. hard to make a 5150 sound bad.
