I sold an '85 Alembic Spoiler with EMGs here on TalkBass last year and a sh*tshow similar to this thread began both in my sale thread, in a separate thread, and via PMs. My bass, unlike this one, wasn't routed out to accept 'lowly' aftermarket electronics and could be easily restored back to former glory with a AXY pickup and preamp transplant. Also, I purchased it already modified, played and enjoyed it, and passed it on gutted of the EMG electronics. It eventually re-surfaced and re-sold here with restored electronics for a lot more money than it left my hands for. Truth be told, it was a fantastic piece of wood with low action, easy playability, and nice, quiet electronics. Would I have liked it to be all original? Definitely, but it was an excellent bass even with the modifications. Was it worth me sourcing the Alembic electronics, scouring eBay for weeks to get it all together or piece together everything needed? Not really, in my opinion, as Spoilers aren't worth crazy money and the bass wasn't lacking in anything other than originality.
What would I do with that eBay bass? Snag it for cheaper than asking price, toss some gnarly jazz pickups in there and cover 'em with carved exotic wood covers, toss on a ramp to hide the routs, and play it.
