Having Thoughts About Burner Electronics

There seems to be, for me, a lot of mystery concerning the sound that comes from a circuit and what components or combination thereof make that sound. Eq is eq... is eq,... in that a freq or bandwidth is really an objective idea. But we come up with a circuit to give us a 'pre-shape' eq curve, and that circuit also often adds a 'color' of it's own. Examples: Joe Meek, Trace-Elliot, Ampeg... Honestly, the stupefying number of preamps (both inboard and outboard), amplifiers, rack-mount systems, processors and pedals available is enough to put a knot in my head. And of course now we're talking about pickups...

For years I've steered clear of active stuff just to avoid the clutter of too many items in the gain-chain! But I now have 2 active basses. So the moral is that if it sounds good, it is good- and that's where the thinking stops. Thank God.

Glad to have the bass, we'll get 'er fixed up. Thanks for the banter Ken, folks!

Edit: Oh, and about my previous post above concerning the sound of the Burner "passive", I don't know what strings are on it. Maybe it's the strings...

The Burner Bass and all other Smith Basses are actually made as Passive Basses, with Passive Pickups, Passive Volume and Pickup controls but with an Active EQ that is either Bass/Treble or Bs/Mid/Tr that is mainly colorless, like a graphic type EQ. The Bass can be set flat in the Active mode and have within 95-98% of the exact sound as the Passive Push/Pull (up position) By-Pass sound. There might be a tad 'bleed thru' from the active EQ circuit when in passive bit it is NOT designed at all to color the sound of the Bass, just to EQ it like you would in a studio, boosting or cutting a particular Frequency point with the range above and below the EQ point shaping the sound.

Do you happen to know the frequencies where the EQ affects the signal for lo and hi? It's shelving, I would assume. I'm just interested.

The Bass 'shelf' then I think was set at 100hz. The Treble is a peak filter and the center is about 3500-4000 hz (3.5-4k).

This means little unless you know how the 'shapes' work. The Treble lower part of the 'cone' is about 1-2k and is cut off at 20k. The Bass shelf cuts off at 20hz bottom and goes up the the mid area at the tail of the shelf.

Tech talk. Means little unless you can taste it from cross town from, just seeing the smoke!

Well I'm going to be very interested to hear/play this baby when she gets back from home. Thanks for all the informative replies.
