Best 7 string ever?
Well, I don't think there's such a thing as a bad tone.
A squire strat through a GX-15 can be a good tone. If you're looking for a thin, tranzistorized, 'itty bitty speaker' tone. As a base tone, I don't think it would be a good idea, but for 3 seconds in the middle of a song, harmonized with a deep, rich, overdriven bass, it could sound great. In fact, I might get a gx 15 and do that on "Breaking into Satan's House."
It's all in how you use them.
I don't like the tone of the bridge pickup stock on my UV777BK. I'm going to order an Evolution 7 tomorrow, I think it has the tone I'm going for.
It's like the SS VS Tube argument, no one wins.
