I love my American "Qualifier[1]" Fender Dimension V HH bass, in the sense that physically it's an absolute joy to hold and play (with a good setup and a hardwood neck shim). But after some soul searching, I am forced to admit that the pickups are, at best, OK.

They're fine. The pickups are fine. If you only use that fourth position "both inner" setting or you're playing country where the harmonics don't matter, they're fine. They have a fat bottom and an aggressive high end peak that is great for modern country, hard rock and metal tones. Which is fine. Did I mention that it's fine? But the harshness of that high frequency peak wears thin pretty fast. Otherwise, there's nothing really wrong with, or particularly special about, the electronics. (Ok to nitpick, the treble knob doesn't cut very far, so it's practically useless for flats and begs for a passive tone mod, but you could say that about almost any modern active preamp.)

There's no information whatsoever about the bass as far as I can tell, so I dug in and took a look. Here are some pictures of that.

Cutout looks reasonable.

Love how the poly finish pulled up around the screw holes. There's also a lot of finish overspray in half of the neck pocket, which made the neck (and therefore the strings) sit at a funky angle until I spent some nervous quality time with sandpaper and a small paper shim. Not impressed with the finish work from US Fender. This was *before* COVID; no excuses.

Looking closer at the electronics first because ... hey a wire fell off! I didn't even pull on it.

Uh oh, wonder how many of these other wires are also inadequately crimped. Ah well I can solder it on.

A TI TLE2062 JFET dual op-amp with a split power supply, no bass bypass capacitors, that's nice. But only a dual op-amp definitely limits our options for the tone circuit, right? Looks like it sounds, quiet and high quality but just a simple treble middle bass.

The non-rewirable 5-way switch is a disappointment. If I decide to go for more complex pickup options (the neck-only position should be a single split coil) will have to spend some quality time figuring out where on that PCB is actually the input. (Yes I could swap the preamp but it's actually pretty good and there's a chip shortage.)

Moving on to the pickups themselves...

The covers just come right off. Well, that's handy! Look at that magnet structure. Just look at it. Truly overengineered in a way that makes my internal engineer very happy. I mean not in one that delivers live-changingly awesome tone, but it's still fun to look at.

Comparing it to a 5-string J sized pickup (bartonlinis tend to be a little undersized):
IMG_1952.jpg


Hmm, so you might think "they took a standard 5-string double-J pickup and shoved it into an oval case" and maybe that's how they started, but the actual end result was a pickup that looks for all the world like a Bartolini BD5C[BC] with an oval drawn around it, 100.3x36.8mm. The other pickup available in this shape is the Delano SBC5.

Two great options, but both very civilized. I would choose Delano for articulation, but I wanted to keep some (just some) of the "overwound monster" feel of the factory design.So I found a couple of new old stock BD5C bridge pickups on eBay. This should keep the neck dominant and deliver some old school fatness.

But in the interest of keeping things completely reversible, I made an adaptor (link to STL provided). Didn't even trim the pickup leads, just stuffed them into that huge cavity. No drilling!

(3D enthusiasts, please excuse the horrid Z-banding. I have a new extruder drive on order. I figured it's inside the body of the bass and nobody will notice so no need to reprint it...)

There's a cutout on the back for the wires, and it has holes for either the two- or three-screw versions of the pickup. I left a channel for the wires out the side, and later realized there's enough space underneath the pickup to park a small car, so it's not really needed.

And they're in:

Notice the bridge pickup is upside down. Yes I did that on purpose. This means instead of "inner" and "outer" coil settings, you have "both neck" and "both bridge". This puts a little bit of midrange into the "both neck" making it usable in that "vintage deep neck coil" way. It also makes the neck coil more dominant in the "both bridge" setting, which gives it a "modern J" feel. Everything else is the same.

The only limitation here is that the "just neck pickup" setting is too honky (well I *did* put in a bridge pickup), and should probably be replaced by a single-coil setting (split coil) or a neck pickup wind or a clever highpass humbuck setting (G&L style) or... but whatever. It works so well in the multiple-pickup positions I am going to leave it. For now. :)

3D files on Thingiverse Fender Dimension V Bass Bartolini Pickup Spacer by tekhedd or DM me, they're not images so I can't really upload them in the thread. :D

So...now there is one place somewhere online with detailed closeup pics of the inside of an active American Dimension bass. And free STL files to boot. (Should be easy to adapt to 4-string also.) Hope this helps.

(Oh, and yeah, it sounds great.)

1 - Fender really dropped the ball on Deluxe vs Custom vs Standard on the American Deluxe basses, didn't they?

Very interesting thread. Great pictures and your insight here is appreciated. I bought my USA Deluxe 5 HH new in 2014. It's bone stock and I gig it regularly. I bought it primarily for Young Country as an option with my Precision V.
I always found the top end very crispy and never used the treble at all. Zeroed out with the mid and bass boost maxed. I was using, for the longest time, DR Sunbeams and recently switched to EB Cobalt flats which has improved the bass. I also changed amps, from a Hartke LH 1000 to a Mesa WD800 which radically changed everything. I've found eq solutions and strangely, the most effective fix was a matter of technique and not gettin' into the innards of the thing.
I just pluck closer to the neck heel. Gives me a deep, double bass tone (center position on switching) and I'm more than happy with the thing. It's been on stage 100's of times as has the Precision V. We were a busy Country band, ditto the Irish-Tradional-punk band I'm in now.

The WD800 switch was the most significant tonal change I had made. I used the LH1000 since new in 2007. That was an easy amp to work with. Ever reliable, always plenty of juice. Clean and bassy.

At 62 yrs old now, I'm not pursuing gear as a much as ways to endure hours on small stages or multiple gigs over a few days. Personal energy is what I wish was amply stocked at our local stores of choice.

I am jealous of your bass, that transparent red finish is the winner of the Dimension line. Mine's violin burst, but it sounds great and has that dried-out body vibe of a vintage Fender. Ditto the Precision V.
A pic just 'cause Dimensions are cool basses.

That's what I'm running. They're an interesting flat. I now tend to use them for any occasion I would previously have considered rounds.

Nice! Would that have been a "tobacco burst" back when everybody smoked? Unlike every other Dimension, I think yours is one of the few that looks good with the stock white pickguard, but it still might look even better with the right pickguard. There's a reason, I think, that when you search for Dimensions on eAuctionSite the first 100 things that turn up are pickguards. :)

<EDIT> Wait, you run with the mid and bass controls maxed? Now I'm *really* curious about the tone circuit, maybe it's a semi-passive circuit isolated between the two op-amp stages? Because you can't get away with that on just every bass. Anybody got a schematic?

I know zip about it's innards. I bought it because I didn't bond with any of the EB active basses I tried, the Fender tone, and feel are just 'home' to me.
Yeah, I just run those 2 maxed 'cause the treble boost is chromey, almost shattered glass crisp. In my tonal realm, bass is bottom end, no high-end attitude wanted.

Pickguard Dallas' own MK Holloway makes leather pg's. She made me a beautiful one for my Precision V and it fit perfectly. I meticulously drew the outline and she did the rest. I've been meaning to have her make one. Since she's right down the road from me now, I should give her a call.

Wow, well done. U da man! ;)
 
I know this is an old discussion but figured I would ask if anyone still watching this thread could help me find the 5 way switch. Being that it’s a sealed pcb one it’s extremely hard to find. I found only one on Reverb but was already sold. Please let me know if you have any ideas on where I can get one. Fender part # 009-5338-540
I’ve tried Fender, eBay, Reverb, etc and no sign of one.
