Malthumb it was probably more like the hands of a skilled engineer or some kind of pedal or both. An Alembic off the shelf, has an entirely different tone than the Fender, I don't care who hands it's in. Not a bad tone, just not a Fender. The Alembic is in probably the best hands it can be in (Stanley Clark), & his bass sounds terrible. Also you never know what these cats are playing through or what type of modifications they have done to there basses. So the bass you heard might only be an Alembic by name only, the guts are someone else.
Ssabass,
Here's where I GOTTA disagree with you on a number of points. I'll start with the easy one. Stanley's tone is Stanley's Alembic tone, not THE Alembic tone. His primary bass is strung tenor (ADGC) and his signal chain is highly processed. The guy last night played through a BBE Sonic Maximizer and an Eden 115 combo. That's it. I spoke to him before and after the set, including when he was taking down his rig.
I can assure you that all Alembics DO NOT sound alike. I have played dozens, owned 6, still own 2. The two I still own couldn't sound more different. My 4 string has piano sharp clarity. If it were a singer, it wold be Jaheim. My 5 string brings thunder. If it was a singer it would be Barry White. Same can be said for various Fenders I've owned. I've owned, over the years, 3 Marcus Miller Signatures and they sounded very different from each other.
Keep in mind that a number of very popular songs you may have heard a lot were played on Alembics, but they don't have the Stanley Clarke sound. Just a few that I'm fairly certain of....
Car Wash and I Wanna Get Next To You (Rose Royce), Strawberry Letter 23 and other Brothers Johnson songs on the same album, most anything by Kool & The Gang in the early to mid 80s, most anything by Wierd Al Yankovich.
Fenders are great for most situations. So are Alembics. I can make my 5 string Alembic sound like a Fender. I cannot get my 4 string to sound like a Fender. The clarity is just too focused. I'd have to signal process to get a Fender sound. At that point i'd just use a Fender or one of my Music Man basses. I cannot get all of the tones available on either Alembic out of any Fender I've ever played without some serious signal processing. Not a knock on Fender, because no one NEEDS all the tones I can get out of an Alembic, but the thing is, they are there if you need them.
At the end of the day, though, REAL tone comes from the fingers and mind of the bassist. The issues you and I are haggling over are millimeters on a football field.
