Guitar World Verdict

For a relatively new brand, Sire has developed some serious market presence – and on the strength of even this entry-level V1, it’s no mere hype. This bass holds its own against similarly-priced rivals for build quality and sound, but possesses an almighty trump card in its stunning playability.

Pros

+
It’s solidly built, comfortably-weighted and gig-ready.
+
The neck feels like it came straight from a bass more than five times the price.
+
Excellent value - undercutting most Squier Jazz models, but not leaving you feeling remotely short-changed.

Cons

-
Even in this lovely colour, it’s not the most visually-compelling Jazz-alike out there.
-
The pickups are functional but unspectacular – not a deal-breaker at this price, but it’s worth factoring in an upgrade given how good the rest of the package is.

What is it?

If you've been in the market for a budget or mid-priced bass at any point in the last few years, you can't fail to have noticed Korean brand Sire.

Built in a dedicated factory in Indonesia, these instruments have absolutely snowballed in popularity of late. Reviews speak to the quality and playability on offer for very reasonable prices - but this isn't all.

Lending the company serious credence is the endorsement of legendary American session bassist Marcus Miller. Known as a long-time Fender Jazz Bass user, with a high-end signature model of his own, Miller's 2015 switch to this lower-priced upstart brand was noteworthy indeed.

Build quality

Build quality rating: ★★★★☆

If you're expecting a sad slab of plywood with an orange-peel finish and mile-high action for that money, you simply won't believe what you're getting here.

This V1 is in a great color - called ‘Tide Pool’, it's close to Fender's classic Lake Placid Blue. The body shape is a close analog of a traditional Jazz, although with slightly more snub-nosed cutaways and Sire's rather bland-looking headstock.

I'd also swap the black scratchplate for white or mint-green, but it works with the dark rosewood fretboard; in itself, the latter is now a bit of a spec-sheet boast on a cheaper instrument, as most rivals slum it with lower-cost rosewood alternatives.

The body wood is quoted as mahogany - an unorthodox choice for a Jazz, but it contributes to a very manageable overall weight and good on-strap balance. And let's not beat around the bush: that Edgeless neck is remarkable.

The profile itself is fairly slim, and the nut is the usual Jazz Bass 38mm – but the heavily rolled edges and the smooth satin finish elevate it to a plane far beyond anything else you'll find for this price – or indeed, for several times this price.

Without a hint of exaggeration, this is the kind of neck profile, and the kind of superb playability, that calls to mind a modern American-built Fender – and not an entry-level one, either. It’s staggering to think that a $329 bass can be so addictively fantastic to play - I can’t rule out witchcraft being involved.

Sounds

Sounds rating: ★★★½☆

In terms of pickups and electrics, though, the V1 doesn't play any fancy tricks - it's purely a conventional J-style configuration. The pickups themselves are Sire's ‘Basic J’ set - the lowest rung on the electronic ladder, only appearing on the V1. So, are they as perfunctory and uninspiring as that rather matter-of-fact name might lead you to believe?

Well, no – it's just as worthy a Jazz Bass sound as most others you'll find for this budget. With my preferred Acoustic 360 and Gallien-Krueger clean tones dialled-in on my Line 6 HX Stomp, and both pickups on full, it's the characteristic scooped midrange – a little darker and more subdued than some rivals.

The V1 would certainly fly higher with a slightly hotter and more vibrant set of pickups

But my favourite Jazz Bass tones come from rolling back the neck pickup a little, to bring out the chime of the bridge pickup; the Sire is no exception. Now, there’s a crisp growl with more upper mids and a nice, rounded top end which takes well to a pick and a more overdriven signal.

It’s still not the punchiest or the most characterful, but it’s solid and gets the job done. The V1 would certainly fly higher with a slightly hotter and more vibrant set of pickups, though - the overall quality of the instrument, particularly that brilliant neck, warrants it.

Verdict

All things considered, the Sire V1 is quite an achievement. It sits at a price point that undercuts any equivalent Squier, but offers playability that should give Fender serious pause for thought - that neck genuinely compares well to American-built models over five times the price.

For sheer playing comfort, I’d venture there’s simply nothing to touch it at this price

It’s not quite as sexy-looking as some rivals, and the sound is more functional than inspirational but, in many ways, the measure of a good instrument is in how often you pick it up, even for a quick unplugged noodle – and I’ve been doing so constantly with the V1, each time marvelling at how such a fantastic-feeling bass is available for so little cash.

For sheer playing comfort, I’d venture there’s simply nothing to touch it at this price.

Build quality	It’s solid but unspectacular, and doesn’t look as arresting as some rivals – but it does feel as though it’ll easily stand up to live use.	★★★★☆
Playability	A richly deserved five stars – it’s utterly addictive. That Edgeless neck is worth its weight in gold, feeling for all the world like a high-end modern bas	★★★★★
Sounds	It’s perfectly good for the price, but the tones don’t quite live up to the standard set by the playing experience. If ever a bass deserved some good aftermarket pickups, though...	★★★½☆
Overall	In most ways, this is a very credible entry-level Jazz-style bass. In terms of sheer playability, though, the V1 is a true giant-killer.	★★★★½
