Mystery extra wire in battery cavity - 2019 Strandberg Boden Bass Original

Hi everyone,


I recently acquired a 2019 Strandberg Boden Bass Original (equipped with Nordstrand Zenblade pickups).


When testing the bass initially, everything sounded completely fine and all controls/EQ functioned normally. However, I’ve recently moved and currently don't have an amplifier set up to do further testing.


While replacing/checking the battery compartment, I noticed an extra black wire running alongside the main battery harness through the route into the battery cavity.


Here is what I've observed so far:


The 9V battery snap connector itself is fully intact, with its own red and black wires connected properly.


This extra black wire is unconnected in the battery cavity, with about 3 fine strands of copper exposed at the tip.


The battery cavity is made of plain plastic with no shielding foil or metal contact plates, so there are no signs of a snapped solder joint inside the battery compartment.


I opened the main control cavity to inspect the harness: all solder joints on the pots and jack look factory-clean. The bundle of wires includes a sleeve/tubing end that appears to be unused/empty, matching this wire's path.


Since I can't plug in and test for noise or active/passive output right now due to the move, I wanted to ask:


1. Is this extra black wire simply a factory dummy/spare ground wire from the harness for this model?


2. Should I just insulate the bare copper tip with electrical tape and leave it inside the cavity?


I've attached photos of the battery cavity and the control cavity for reference.


Thanks in advance for your help!

As someone else mentioned, I'd suspect a bridge ground wire that came disconnected either under the bridge or from its ground connection in the control cavity. Can you point out which of the wires in the control cavity this is?

Barefaced Amp Prototype - Zero K7

Would love to pair this with a Big Baby 3 (or a PAIR of BB3's if there were to be a stereo option....? maybe....? hint...?) for the 'ultimate' FRFR rig to swap between bass and guitar stuff. So far, I haven't been super impressed with anything on the market and would otherwise probably go for a Crown DSP rack unit.

As someone who ran a pair of BB2 cabs and a rack power amp for a stereo PA with synths and samples and some vocals, I think you'd enjoy that :)

Xotic XJ-1 & XJ-1T 5 String Jazz Bass

Not bad....about 17 years since this thread started. I remember all the Xotic hype years ago....seems you don't really hear about them these days unless you go looking. I enjoyed some of the tech they used to cancel hum and liked some of the cool touches like the wooden p/u covers. All of this IIRC.....good luck on your search.

What scale doe she use in this tune?

The reason why I ask ius because everytime I come up with soimething like that, I only go up and down the mother scale, like straig up or down over Gm on the 12th fret ( g string ) down to the 10th on the A string when the cord is Gm , which results in sounding always the same ( at least for me ). Its like, it doesnt sound "surprising ".
yes this cat kills it!

If you're looking to enhance your phrasing and Melodicism trying including slides/hammeron/pull offs between the b3-4-5 and the b7-root scale tones. It may help adding a vocalistic singing quality to your soloing—thats exactly what he does in this music clip.

Im not sure what you mean regarding the 10th and 12th frets; keep in mind the song/groove is in Bminor mostly in 2nd position, and he crushes it with minor pentatonic/blues scales fills at the 9th, 14th positions.


Hello ! I will show you a video of a bass player from Brazil who I follow on instagram. He overlines a tune with his own lines. The groove its just so cool. My quieston is: what scale does he use when he goes up the second time, to the 15+ frets area?
also the other two times he goes up .

all three fills are based off the B minor pentatonic scale
*note im trying to write shorthand in text instead of notation so its assumed you know a 1oct minor pentatonic scale in position

±1:06 Starts in 9th position—7th position​
descending minor pentatonic hammer-on lick includes #4 on [G string] 4-#4-5\4 b3, [D str] 8 b7 [A str]5 4 [E str]b3 1​
±1:14 Starts in 14th position​
starts with a [G string slide or hammer-on] @ 14th fret b7–8 4 5 b7, 1 b3 4 5\3b 1​
±1:22 Starts in 9th position​
descending minor pentatonic pull-off lick includes #4 on G string 5-#4-4\b3 1, 4 b3 1 b7, [A string desc] 5 4 b34 5, 1​
Good luck hope it helps. He's a great player to follow!

Acoustic Image Clarus SL

It can work for Electric Bass with the tone stack. I have A series III Coda R combo, Series III Focus R supposedly 1000 watt head and yeah, no issues powering a 810 or 610 ( not my cabs ) and I also have a Series 4+ Clarus Head that I've used at an EB gig with a DoubleShot -- but I get better results for EB with the EA Whizzy 12's. Best to use an EB oriented preamp though although you can also preamp stack if you want.

I have the XTCT with Oxalis pick-ups! I'm not if I can control the mids with the in cavity mid control, I don't see one like what I found online the little blue circle. Found a big blue circular thing right above the low frequency control though but too scared to touch it
I became a bit of an expert in the XTCT and TCT recently and have installed both several times now. Don't fear the "mid trimmer".

Winter build off 2026 - Primal Screamray

I've traced the vol pot issue to a faulty pot, the eBay seller I got it from quite some time ago has kindly agreed to send me another one. Still examining the treble issue.
Treble pot should only connect to the preamp. Maybe re-flow the solder connections to it. And/or look to see if a wire is broken. That can happen stuffing the setup into a cavity if the wires get strained where they enter the epoxy encased preamp board.
