That body style of bass is simply called a single cut, as opposed to a Fender being a double cut.
Before you order a custom from Dave Pushic, or any other luthier for that matter, please consider these three pieces of advice.....
1) Make certain you know
EXACTLY WHAT YOU WANT2) Remember you will get ALMOST what you paid for
3) Make certain you know
EXACTLY WHAT YOU WANTThere are a couple "legendary" DP Custom products floating around that were specced out and made to order for very accomplished bassists who
THOUGHT they knew exactly what they wanted. Dave made what he thought was
EXACTLY what they asked for. The results were like starting a bridge on opposite sides of the Mississippi and then trying to figure out why it didn't exactly come together in the middle.
I'm trying not to single Dave out, because my understanding is that he has improved significantly from those days about 3 or 4 years ago. Unless a luthier is really good at maintaining stability of the basics, the finished product can be tainted by the whimsy of the person ordering it. If the luthier is not skilled and knowledgeable enough to tell the customer "no, that does not make sense", the result can be interesting.
I currently own two custom basses. The first I ordered from Alembic. Alembic started the whole "boutique" or "custom" bass industry in the '70s and they know what they're doing. I chose from a lonnnngggg menu of available options and the store that I worked through (G Guitars ) and Mica Wickersham at Alembic were very instrumental (no pun intended) in telling me what made sense and what did not. That bass continues to be my main instrument. I'm not recommending that everybody go out and custom order an Alembic, because they were expensive when I ordered mine and wildly expensive today. Today a bass like mine would list at almost double the list of the bass I received in 2000.
I also ordered a custom bass from Jake Marchlewski. BEAUTIFUL bass with excellent craftsmanship, but it has its quirks.
It is very difficult for me to adjust the action the way I like it (low) even though I specced it with an adjustable nut. Truss rod access requires removing the Birds-eye Maple pickguard. Because it's a very thin laminate, I cringe whenever I have to remove it because it would be too easy to break it. If I break it, then the routing marks for the neck pickup and control placement would be visible. That's like walking around showing your appendix scar. I also originally specced it with an 18 volt Bartolini pre-amp. Neither Jake nor I realized at the time that the small body and the difficulty involved in placing two 9V batteries in the small compartment would make things get a little....."warm"..... I sent the bass back to Jake and he replaced the 18V with a 9V which works very well.
The moral of that long story is that even though I specced the bass to include the best of things I liked from instruments I'd played for years, I still needed post-sale support from the luthier (Jake was great to work with pre, during and post sale) and there were still some unexpected quirks involved in having the instrument almost totally custom. My understanding is that Dave's post sale support depends on how defensive he gets about the quality of his work and how much of the issue he attributes to your choices. I chose the 18V circuit, but Jake changed it when he realized it wouldn't work for me. He did not take the "I made what you told me" approach. Some luthiers would.
The only thing I didn't spec on my Marchlewski was the body design. It was designed by another Talk Bass member. Here's the first of 4 basses that Jake made for him, so you can see the similarities...
Don't want to pour water on your fire for getting a custom built instrument. Just looking to help you see some of the rocks you might trip over on your path.
Peace,
James
Almost forgot. You wanted an honest opinion on the bass you posted the picture of. I like it. I typically do not like single cuts, but that one is very nice. Some people love buckeye burl, others hate it. Audiences tend not to care. I also don't think the church will care at all what it looks like, as long as it doesn't look like Gene Simmons' "Axe" ax, or have skulls or satanic symbols painted on it. I've played the Marchlewski, my Alembic, and a Music Man Bongo at church services and nobody's kicked me out of a sanctuary yet
