Ash will be "quick" and punchy sounding, a bit edgy, but not bright; adding maple (we are talking about a Custom or Signature, right? If we're talking about a Standard Plus, disregard the top - not enough wood there to matter, honestly, it's just "cosmetic") will add some brightness and "snap" to the soup; mahogany with maple will be punchy, slightly compressed, fat without being "muddy", and you will get a bit of snap/bright from the maple (again, Custom or Signature, not so much with a Standard Plus - but even without the maple, it will sound great)
Definitely a difference!

The soapbar/dual coil (or quad coil, if it's our custom wound pickup) is a bit smoother and more "refined" sounding than even the Bart MM pickup (and we offer the Aguilar AG-4/5M as an option); the MM pickups are a bit more aggressive and edgy sounding, and the Aggie is VERY like the old 70's MM to my ear - but it does not offer the option of the 3-way switching, they felt that the parallel tone was significantly better than either of the other options, and it is hard-wired in that mode. I have the Aggie, and LOVE the thing. Love it.
[/\QUOTE]I'm looking for something with a really sweet, tight, focused midrange and of course good bottom end. I'm actually getting it from another bass that has mahagony/maple and a single MM humbucker but it's not the most comfortable bass for me to play all night and I want dual pickups.
