i plan on purchasing a 6-string in the coming months, and was looking around at whats available. my budget will likely be the 400-600 dollar range. a slightly wider string spacing is preffered, since i play alot of slap bass on my 4-string ibanez. i will also be using this bass for tapping across many genres, death metal, jazz, and many other experimental kinds of music. so im looking for something versatile. ive been looking at the older ibanez sr406, the newer sr506, the esp ltd d4, and the schecter riot 6. what other decent 6ers are available for this price range, new or used? any reviews, pros/cons, or general comments on these basses is appreciated. thanks!
