Wu,
If you think you might regret, just pull the auction. You can always get the money elsewhere.
Andy,
Yes, you just need the single coil pickups and electronics to do the job.
Last quote I got from Alembic was like 3000 dollars with trade-in of my Anniv electronics. That's a lot of money, but they'll then re-tune the electronics based on your bass, so that might be the 'right' way to do. But you can do the electronic swap 'cheaper' if you can find a beat-up series bass, swap electronics, sell the beat-up series, and have Alembic upgrade the electronics. But that might prove to be more expensive, it all depends i guess.
This bass balances decently, since it is medium scale, but it's no where close to balance of bass with longer upper horn. But it's not to the point where it will do auto-head-dive.
Good luck guys. Wood work on this bass is more than justify the price wu is asking. I really think it is a awesome deal, unless wu regains sanity and pull it from ebay.
Takeo
