Ive been gassing more and more for a ERB. And the GT7 is the only affordable 7 string I know of thats said to be good. Where can I get a full spec sheet on this bass, My main concerns are... Nut Width String Spacing Top of fretboard to bottom of neck thickness Sound Playability Now Im also considering a Yamaha TRB 1005 or 6, WHich I think is an awesome bass. As well as the Ibanez Prestige 1005/6. I usually see the GT7 go on ebay for around $1000, But what would be the resale value if I were to take it to Guitar Center and want to trade it, I have a friend at GC who can give me deals gear and all, but just in case he cant, Ya know? Would it be worth buying one and trying it out for a couple of months to see if the almighty 7 string is the right thing for me(Mr Turner I want your input too )? I would be tuning it this way ADADGCF and ADADADG.
