Hi, I bought Jon Liebman's Instructional Funk Bass book a few years back and never did get through very far into it. Crazy when I think of it, I really should have stuck to it but I had a problem. I have two basses, two cheap basses - both with incredible handicaps. I have a squier p bass that would be fine but its defretted and sounds horrible slapped and this horrible ashton 5 string bass with ubernarrow string spacing, terrible electronics. Don't get me wrong though, I got what I paid for them so I'm not complaining. The neck is bowed enough for the bass to be dead in spots after about the 8th fret. :| But this is what stuffed me up learning to slap, this horrible bass is driving me nuts. The string spacing is so narrow that in a pop situation I am tested to my limits just getting inbetween the strings to pop. There is so much ring aswell, it is a constant challenge to keep these strings muted. My question, maybe one of many but are these narrow string spaced basses much worse in terms of muting requirements? I plan to get a btb406 sometime later on this year so hopefully by then moving onto the btb will be heaven. I do occasionally slap my fretless and wow, the spacing makes it so much easier to get around. Has anyone else uses Jon Liebman's book? It seems to be very good.
