Get a great rock sound in a tiny package with the Spirit of Rock Nano Mini Amplifier Head from Hughes & Kettner. Compact at 7 x 3.5 x 3.5" and weighing only 2.4 lb, this amplifier head can routinely deliver 25W into 8-ohm cabinets. With the right 4-ohm cabs, the amp can go as high as 50W, making it suitable not just for practicing at home, but for rehearsal with the band and even for live shows.

At the core of the Spirit of Rock is the company's Spirit Tone Generator, a technology that replicates the sound of tubes even in a pint-sized format. This circuit endows this tiny amplifier with the ability to unleash arena-ready rock tones despite the small size. Whether you're looking for an '80s tone, a '90s britpop tone, or a grunge-like brown tone, this unit will deliver with minimal tweaking of the knobs. Since the technology is all analog, you won't experience any annoying latency or digital artifacting customary among modeling amps.

The amplifier provides easy-to-use knobs. Gain, master, and tone knobs are simple enough to explain. The control to pay attention to is the Sagging knob, which gets to the heart of the Spirit Tone Generator. This knob grants you total control over the power amp's sag, which affects how the power amp responds to being driven, yielding an expressive amplifier saturation. Different values get you completely different tones, making the knob quite useful for emulating all sorts of rock amplifiers. The control also lets you achieve blistering rock riffs at any volume.

The Spirit of Rock also provides features sure to delight any guitarist. Plug a music player into the auxiliary input, plug your heapdhones into the headphone jack, and you can jam along to all your favorite tracks in quietude. The music will pass through in pure stereo from the player to your phones. Use the line output on the back of the unit with compatible interfaces to record an album-ready guitar tone. Finally, the amp's speaker jack allows you to play with 4-, 8-, or 16-ohm cabinets for true versatility.
