I saw someone mention an Alnico 2 magnet in here somewhere I think that's a good suggestion for sure! If I remember the low end can be a bit wooly though if that's not a problem though I know they genereally are very warm though from the one's I've tried their was a PAF style one I tried a while back if I can remember the company it was from at some point I'll post it up, it was REAL good but the wooly nature of the low end ended up being something I ultimate didn't care for overall.
