Pre/PS ala Alembic

croat47 · 15th March 2006, 05:37 PM

Has anyone seen a bass guitar setup that has a PS for the pickups (like Alembic Series I) and a preamp? I suspect it would have a 4-pin XLR type connector (2 for power, 2 for signal).

If so...where? The only advantage I could see would be a "cool" factor. But, who knows.

If not...what problems do you see...besides integration with other systems standards. Would noise in the 4-conductor line be an issue?

I can't see any advantage, other than you don't need a battery in your active bass?. There's no noise problems, the signal from the active bass is low impedance and fairly high level, fed from the putput of the preamp in the bass that makes it 'active'.

Seems to have FAR more minus points than plus ones?.

Does the outboard PS at least make sense? Would be able to get 27v pretty easy if one were so inclined. If you were making your own rig, and NEEDED that power supply...having the signal and PS combined would be nice for small rig-ability.

Also, I would like to point out that I am certainly in no position to question the knowledge and experience of Mr. Wickersham!

I don't really think it makes sense?, using a battery in the guitar is far more sensible, and doesn't limit you to one obscure amplifier type. If?, for some perculiar reason, I wanted a high voltage power supply for an active guitar preamp, then I'd use a standard phantom powered one from an amplifier.

There are a number of active guitars that use two batteries, for an 18V supply - but the benefits seem doubtful?.

Presumably it's a mostly marketing ploy so they have to buy your amplifier as well? - I think their limited popularity rather proves they have no technical advantage.
