It’s roughly the weight of a bowling ball, and about the size of a shoebox, but don’t think for a second that the OR15’s compact stature (and therefore its incredible portability) comes at the expense of character or sonic heft: this pint-sized package is as overflowing with classic Orange tone as its bulkier relatives, delivering clean chimes full of purity and precision, a stately crunch at the edge of breakup, and an up-to-11 maximalism that rings out at full saturation, all with convenience and authority.

Don’t think that 15 watts of power means it’s just for practising, either: this is one of the loudest 15-watters you’ll ever hear, happy at all but stadium gigs, thanks to its robust, proprietary transformers, offering miles of headroom and almost endless possibilities for different gain structures. Indeed, with a simple-yet-powerful three-band EQ allowing you to season your tone to taste, the versatility of of the OR15 is perhaps its greatest asset: roll off the gain and bass for deliciously glassy funk, or do the reverse to turn this plucky little box into a fire-spitting monster, with gorgeously musical articulation even at its most overdriven.

Chuck in a valve-buffered effects loop that puts modulation pedals at exactly the right spot in your sound-making chain, and the OR15 has everything necessary to become the go-to amp for players of any style.
