This bass arrived in March but didn't get around to opening it around my birthday month, and I'm glad I waited! Gorgeous looking bass that was totally an impulse buy directly from GOC's site, as part of their first batch of their new "Chinese New Year" edition finishes featuring swamp ash bodies

  • Scale length: 34 - 37" Modern scale

I generally don't consider myself to be a 5 string guy, but this bias stemmed from my bad experiences with my first 5 string (a :poop: Washburn axxess bass with a maxxed out truss rod and dodgy electronics). Even with headless basses, my only real headless had been a not-good "Phoenix" headless P bass from the 80s. Over the years in the effort to try somethings different, I got a chance to try out a friend's strandberg to get a feel of the body/enduraneck and have been lucky enough to have a Long and Mcquade near me that has a variety of dingwall basses in stock (sometimes up to 2-3 different models!). This combined with trying out Ibanez EHBs let me have a good idea of what I was looking for in a bass.

I had my sights on these types of ergonomic headless basses for a while but didn't find any I liked until I checked a local fb marketplace listing and there was a luthier making these exact type of basses that I almost was looking for at the time (Bors guitars) I ended up being unable to get it as it got sold, but it sparked a genuine curiousity into looking for a bass that combined what I liked about a Dingwall combustion (the pickups, electronics, multiscale neck) and a strandberg (the weight, the headless-ergonomic profile)

This is where GOC comes into play.

I discovered this brand when somebody on FB marketplace (again lol), posted one of their guitars on sale, and while I wanted to buy it, a part of me kept nagging at me to try out a 5 string after years of playing a bass tuned BEAD. I was initially hesitant, as I didn't care too much for the current finishes that were being offered which were just solid colours as opposed to the cool finishes their guitars get., Once this finish came out, I got the credit card ready and placed an order for the first batch! Once it arrived (after some grief from Purolator), fun began!

What I love:

The neck:

Not the best picture, but it's definitely a skinny neck, I have zero problems getting around it, and it really fits my hands nicely (for the record I'm a 6ft guy with long-ish arms and fingers). It's skinnier than the dingwalls I've tried out and the roasted maple feels great!

Out of the box, zero issues with the fit and finish (no tool marks, blemishes), I could almost swear it smelled like the paint from the factory when unboxing it! The body itself is incredibly comfortable, normally I try to prop up the bass a bit more vertical but there's zero issues getting around horizontally.


The nitpicks:

While I'm loving this bass right now it's not perfect. While I don't need it to be, I do admit the tuners at the bridge are stiff to turn. I'll most likely dissassemble the bridge to see what's going on and lubricate it, as it already has thrust bearings so I'm not sure if it's something to do with the machining.

In terms of action it's super low out of the box (4/64ths/1.5mm on the B and G strings), but once you get past the 12ths fret the action starts getting high for my taster (6/64ths/3.5mm on the B string, 3mm on the G). I will most likely find some sort of shin that fits the neck pocket in the future. While it's not a deal breaker, I do like having uniform action throughout the entire length of the neck, I have a good feeling the fretwork itself is good enough to be able to do this like a champ!

The preamp works fine it and the the pickups while good, the preamp itself isn't anything special and produces slight RF noise/hiss(?) when cranking the treble knob. It's a bit of an odd layout (coming from an Ibanez user), but hopefully the replacement preamp I get will fit the narrow control cavity.


Current verdict: (for both now and after said honeymoon phase)

Overall I'm really liking the bass, especially it being the first brand new bass I've ever bought up to this point coming from an exclusive stable of used instruments. It's going to sound next level once I get around to installing the nordwall dingstrand pickups I got, sourcing a Dingwall rotary switch for a decent price, and finding the right preamp to replace the current one! I'm hoping to get sound clips (maybe a video) within the month, if I don't it'll be a soundcloud link posted in the thread below!

Interesting bass and company. Their "about" page says they were founded in Missouri in 2008 and they deliberately hide their identities. Weird.

It looks like a nice bass, but if you feel it needs a different preamp and pickups, and the tuners are a bit problematic on day one, then the low price (compared to a Dingwall Effigy at least) loses some of its appeal.

Keep us up to date on how it evolves !

It's not so much a complaint on the sound, I find the preamp/pickups are perfectly usable out of the box, in my case I just felt like I had to chase the Dingwall tone dragon lol


As for the company itself, I had bit more confidence than Amazon brands like ivy, as they're pretty active on social media (Instagram @gocguitarsofficial) and frequently feature both in progress shots of them making the instruments at their factory as well as players playing their instruments all the time (a good mix of endorsed/regular players), more so their guitars than their basses.

From what I've researched, the basses they've been doing have been a more recent venture from 2022-2023 onward, and they're good with feedback which makes me pretty excited to see what more stuff they got cooking up (in my case I really hope they come out with their skinny stingers with a reworked tremolo!)

I wish they kept this post up but when I saw this shot of the bass on the factory lighting as well as another one showing them ready to ship, I was sold.

While the only slight is that they're currently exclusively marketing to the modern metal market, this bass is more than capable to do more that that. They really are lacking in terms of sound demos online, but I want to change that!

Ill shoot them an email to see what to do about the stiff tuners before tearing the bass down and giving the hardware an experiment of lithium grease/kroil lol (probably just very slight lithium grease)

Moly grease and some thrust bearings. Because of the high turns ratio and the small, closely spaced tuner knobs, it's hard to get them to turn easily without lube and bearings. If there's not enough shaft length to add the bearings, teflon washers will still help some. The bearings are like $10 on Amazon.

Here's a NOVA bridge that has the bearings incorporated into the design, which all headless tuners should have.

I might look to replace/add to the current thrust bearing down the line if just lubricating doesn't work, I was looking at these ones but I gotta take measurements as I'm not sure what sizes would fit this bridge

Ive been also posting in the GOC club thread, but I'm in the process of sizing Fretillusions inlay stickers in their gray iridescent abalone finish

Outside of that, I bought a set of Canadian Dingwall knobs at a good price locally,

I'm currently still deciding on what replacement preamp to get (a few weeks in, I'm getting a bit of hum playing through an amp, and if I use a wireless the volume doesn't turn all the way off even having the knob completely CCE set to 0), currently leaning towards the lusithand dual filter.

Did you end up shimming the neck? Thinking about doing it to mine.
I did, the neck pocket is kind of oddly shaped but I cut a partial shim using a playing card and that did the trick.

In my case Im considering adding one more playing card to try to see how uniform I can get the action but I feel that'd be pushing it as I managed to get the action super low already with added relief

Rad. I've never tried to shim a neck, any videos to follow? I've watched a few and it doesn't seem like rocket science.
 
I have been using blue painters tape for years. Easy to cut the shape you want and being able to stick down. Makes it easier to put the neck back on. Plus you can add or remove layers to get the exact amount you want. And tape is made out of paper/wood.

My problem with tape is that it's like sandpaper in that it compresses over time, playing cards/wood shims don't due to them being laminated.

To get an idea, stewmac's video isn't bad into what it does outside of it being an ad to get you to buy their shims.

For me, I just removed the neck, traced the bottom of the heel on a playing card so it covers as much surface area as I can to avoid leaving gaps. I cut the playing card based on what I traced, and check how it fits in the neck pocket. It's not going to cover the entire pocket but about half of it, which is fine. I then use a hole punch clean up the holes of the bottom two screws and that's pretty much it.

Some companies like ibanez I've seen people put a small strip of sandpaper at the heel, or stick a business card, some people even just throw a pick inside. As long as you can cover a decent amount of surface area (you won't be able to make a full pocket one with a single playing card) you should be fine as you want to leave as little of a gap in the pocket as possble to avoid issues down the line
