I have a Jazz bass that I would like to upgrade the pickups on, and I also have VM Fretless. Although the Jazz is mainly used for practicing, I would like it to have a tone that would be more orientated towards the slap kind of sound (if that makes any sense!). I have read on a few ocasions that the Duncan designed pickups on the VM are good for the "slap tone", but as mine is a fretless, I have no experience with slapping it (sometimes I want to slap myself though! ) So, as you have seen in the poll, should I upgrade the Jazz and leave the VM alone, or move the Duncan Ds to the Jazz and upgrade the fretless? Please note that the only pickups I have available (in my current price range) are: Artec VJAZZ (I have never heard of these!)
