A friend built this board for me and actually stained it with espresso.
Pedals are a mix of straight cheapos, closeout bargains ( nonos) and boutique. Here's what the Keely sounds like on bass and guitar

I used to own the Keeley DynoMyRoto. Stupid name but a great sounding pedal. Not just the Leslie but flanger and chorus too.

Leslie (real cab or a pedal) is a great effect with a 12-string bass.
 
Question for the tech heads. I just purchased a bass with a single Passive seymour duncan smb‑4d which I've read is a common replacement pup for a MM Stingray. The question is ( drumroll please) If it has 2 volumes and one tone is it wired in series ? Description says one volume for each coil . Will I still get a Humbucker tone ? Information, comments and opinions welcome.
If I get your question correctly, you have a single pickup bass with two volume controls and a tone pot and you want to know if the volume pots are wired in series or parallel.

First that's a pretty unique wiring for a single pup bass, but I guess it'll work. The pickup can be wired to the volume pots in series or parallel, you'll need to look at the SD website to see what color wires give you which result. Second, you will only get humbucking (elimination of hum) if you turn both volume pots on, even if one is barely on and the other maxed you'll get hum canceling. You won't get a true humbucker sound unless both volume pots are at about the same volume. If you solo either volume pot you in essence will have a single coil sound probably similar to a Jazz bass, with a degree of hum included.

Again, a separate volume control for each coil on a single pickup bass is fairly unique, can't say I've ever seen one done that way. Traditionally you'd have two pickups with two volume controls and a coil split switch to drop a specific coil out of the circuit on each pickup. As for series vs parallel, I used to put s/p switches in basses but 90% of the time I just end up playing in series mode, so I don't use that switching protocol anymore, I just wire it in series and leave it that way. It's a preference thing.

Edit:
Here's the SD wiring diagram for your situation….

I could be mistaken but I think that looks like parallel wiring, maybe JIO or Chucky can chime in on it. Here's typical Bartolini wiring, don't know if SD uses the same color coding to their coils…

Thanks. What I'm hearing then is this bass will have great tonal variety which for me is the true reason for adding an instrument to the stable. I'm getting excited. I'll post pics in due time.

That it should.
Actually, depending upon the pup location you might have a sound similar to a Warwick Thumb bass (which is one of my best sounding basses). If the pup is in the typical MM location you'll in essence have two Jazz pups stacked next to each other, each with its own discrete volume control, similar to this…

…this thing is an absolute buzzsaw of a bass, very aggressive. Can't wait to see yours and hear your thoughts on the unique control layout.

Holy s*** that is beautiful. Mine is a budget bass. Now if the biggest knock on lower end gear is the electronics having a stock SD pickup helps alleviate this issue partially. When Sweetwater send pics I'll have the reveal.
