The JS series represents Jackson's most affordable models ever - you can bag any of them on the street for under £300 - thanks to Chinese construction, but they don't skimp on quality.
With two own-brand humbuckers and a two-point non-locking vibrato, we're deep in starter territory here, but while the pickup selector and tuners feel a little flimsy, everything else about the JS12's construction points towards a much more expensive guitar. And crucially, it retains tuning well, even with plenty of vibrato abuse.
When you're first learning, a low action can really speed up your progression, and judging from our review model's slinky playability, the JS12 won't give you any problems in that department.
But while it doesn't feature the compound radius of our other review models, the 305mm (12-inch) fingerboard camber has stood Gibson in good stead since the 50s, so you won't find any complaints from us here.
Plugging in is where cost-cutting can reveal itself, but the JS12's high-output humbuckers chug along nicely, although the bridge's proud saddle screws make palm-muting a tad uncomfortable.
While the pickups have plenty of low-end, the highs are a little lacking, and individual chord notes can struggle to cut through.
That rolled-off treble pays off for clean tones, however, doing away with the thin, ice-picky nature of some lower-end axes, instead offering clear, punchy tones.
