This is an ex-demo TRBX204, from Yamaha's shop in London. I've had the stock PJ pickups and preamp replaced with just a Dimarzio Model P and passive vol+tone controls. It's strung with 50-65-85-110 Daddario Pro Steels.

All around, this Chinese 204 is more basic and purely functional than the Indonesian 604 I had a few years ago, which was twice the price. Nonetheless, the woodwork and the finishing are clean and without obvious blemishes: this is still a conscientiously-made instrument. The body is contoured on both sides.

The 304, 504 and 604 have Ibanez-SR-thin necks, but the 174 and 204 have neck specs similar to the current BBs: 1.57" nut, 0.830" at the 1st fret, 0.960" at the 12th. The neck feels quite raw for a satin finish, the fretboard was glad of a drink. The tuners didn't inspire confidence, but do the job fine. I'm not a fan of preamps so I can't judge it other than saying it did what I expected it to, and the pots felt nicely solid.

The backstory, should you care 😁

I had a Yamaha BB424 and a heavily-modded Squier Matt Freeman, and loved them: both had strong characters and were really enjoyable to play. GHS Boomers on the PJ, Pro Steels on the P.

Unfortunately, I hurt my shoulder and it didn't mend properly. As my basses were now a couple of pounds too heavy for me, I replaced them with a pair of very light G&Ls: an SB-1 for nickels, an LB-100 for steels.

As often happens on TB, flats interfered with my plans: having started with Pro Steels + a Model P, the LB-100 now has Chromes + a Lindy Fralin, and is my main bass.

Which left the Dimarzio and several sets of Pro Steels unemployed. Having figured out the hard way that shopping with G&L is russian roulette with only one empty chamber, I chose a cheap, light and reliable home for them. For the simple music that I'll play on it, this modest bass will be quite enough.

I considered keeping a J pickup, adding the versatility of a pickup selector and VVT controls. But really, once I've settled on a combination of pickup and strings, all I want is a tone knob; anything more and aimless fidgeting creeps in.

Finally, why did I buy the Yamaha shop's demo model? Because they had weighed it: 6¼ lbs. Yeah. Please.
 
Nice.
I'd only install the J bridge pickup, for OCD healing purposes 😁
If there was a bridge pickup left unconnected, that would get on my nerves far more than the empty space: I don't like things that ought to be useful being used as decoration. This is a simple instrument doing a simple job, the disused rout seems to underline the point.

Also, if its good enough for Malcolm, it's good enough for me ☺️

Maybe it’s a candidate for a refinish!
Block the bridge pickup
Turn it active with a passive roll off?

Change the bridge pickup for somthing else? Route it out for a soap bar or musicman?

I too found it enjoyable daydreaming about what I might do it. But when it came to action, those daydreams all slipped away, even the basic one of simply leaving in the bridge pickup and wiring it VVT with a toggle.
 
Congrats!!
6.4 lbs is insanely light and I've only seen Glary basses that were consistently that light.
How does it play?

The action won't go as low as I had on my Yamaha BB424, which for the straightforward rock stuff I bought this for is fine. Fiddly Jamerson lines reveal the talent gap between JJ and RR 😅

It doesn't have the depth of character that my Matt Freeman P had, but it's doing okay. After my G&Ls the frets seem very low and rounded. I'm wondering if the aftermarket bridge on the Matt Freeman had harder saddles than this. Does that sound possible? I do sense that I'm losing an ounce of harshness that I liked with that bass.

The brass saddles are MUCH softer than the steel but I'm not sure that makes any difference tonally.
I replaced the bridge on my Tribute JB2 with a bent Fender bridge.
Tone and sustain are identical but the bass is now about 10 ounces lighter.
The lighter G&L tuners also helped it loose weight.
