Going from one speaker to two can add depth, dimension, and punch. Here are 10 from across the stylistic spectrum.

This oversized closed-back 2x12 aims to emulate the response of a 4x12 with added low-end punch and can be preloaded with a handful of different speaker options.

This newly designed cab is up to 35 percent lighter than a normal 2x12 set up. It also has a removable rear panel and comes loaded with Celestion Zephyr speakers.

Modern metal-ers will rejoice with this 120-watt closed-back cab that is constructed with marine-grade Baltic birch. The rear-mounted Celestion V30 speakers round out the package along with the twisted jute-dipped grille filters.

The standout feature of this cab are the side vents, which give your sound a wider feel. It’s constructed with 13-ply void-less Baltic birch and is available with either customized speaker options or totally bare.

Classic styling meets modern construction in this retro-flavored vertical cab. The Celestion Seventy 80 speakers offer 160 watts of power, and the angled setup is decidedly British.

You can’t miss the trademark Orange vibe of this beefy horizontal 2x12 cab. Brit-style tones are right at home with a pair of Celestion Vintage 30 speakers and a closed-back design.

For fans of that unmistakable chime, this Vox cab not only matches the vibe of an AC30 but spreads the sound out a bit with its open back. A pair of Celestion G12M speakers aim to offer clarity and warmth.

Designed to King Eddie’s demanding specs, this straight-front cab is a powerhouse and features old-school tilt-back legs. Inside is a pair of Celestion G12H speakers and a very handy built-in head-mounting mechanism for the EVH 50-watt head.

As a tribute to the sound of late-’60s rock guitar, the PRS HDRX line is vintage flavored and full of vibe. This closed-back cab features the decidedly British Celestion G12H-75 Creamback speakers and poplar plywood construction.

The wood wizards in the cab shop at MojoTone offer a mind-boggling number of options, right down to the piping and Tolex. This one comes stocked with Celestion G12M-65 Creamback speakers and an oval-ported rear panel.

A faithful recreation of the Germanium Mosrite Fuzzrite with a modern twist.

From the years of 1966 to 1968, Mosrite produced two distinct fuzz circuits---one outfitted with silicon transistors, the other with germanium parts. Of the two, the germanium version is by far the most rare, with original designer and Mosrite employee Ed Sanner estimating that around 250 ever made it out the door. In that final year of production, Mosrite shifted exclusively to silicon parts, making germanium components a thing of the past. However, by 1968 the public was hungry for fuzz, having heard it on a handful of recordings, most notably "In-A-Gadda-Da-Vida" by Iron Butterfly and "Incense and Peppermints" by Strawberry Alarm Clock. These two buzzy, sinewy fuzz tones were part of a wave of psychedelic rock gaining traction in the mainstream, and both were recorded prior to the introduction of the silicon Fuzzrite.

Other purported users of this early Fuzzrite circuit include Ron Asheton of the Stooges, Norman Greenbaum on "Spirit in the Sky", Henry Vestine of Canned Heat, and many others. Catalinbread have a germanium version at their disposal, and we've used it as a benchmark to create an extremely faithful version with a modern twist. Just like the original, the Catalinbread Fuzzrite Germanium includes two NOS PNP germanium semiconductors with a polarity inverter IC so it plays nice with all forms of power. Unlike the original, Catalinbread added a toggle switch to shift into modern mode, significantly beefing up the low-end content to suit more contemporary rigs.

The Fuzzrite Germanium is out now and available for $179.99 at participating retailers and catalinbread.com.

The all-new HT series offers "heat treated" pickup technology along with the Cutlas HT, StringRay HT, and Sabre HT guitars.

The Ernie Ball Music Man Sabre HT guitar delivers an incredibly dynamic and responsive playing experience. The pickups are able to achieve an ultra-high-output, powerful low-end response while retaining a distinctively clean, clear tone and definition at lower volume control levels. The HT (Heat Treated) bridge pickup utilizes patent-pending heat-treated pole pieces with a large ceramic magnet and an overwound coil that gives the pickup higher frequency harmonics and excellent touch sensitivity. The Sabre's custom-wound neck humbucker also features a large ceramic magnet and has been wound specifically to pair with the Sabre's HT bridge pickup. In other respects, the Sabre HT shares many of the original Sabre guitar specifications such as a contoured Okoume body with a thick maple top, Schaller locking tuners, and 22 stainless steel frets. The Sabre HT is available in a Yucatan Blue, Raspberry Burst, Showtime, and Snowy Night finish.

The Ernie Ball Music Man Cutlass HT showcases new custom Music Man pickup technology delivering an incredibly dynamic and responsive playing experience. The pickups are able to achieve an ultra-high-output, powerful low-end response while retaining a distinctively clean, clear tone when rolling back the volume control. This set of three HT (Heat Treated) pickups uses patent-pending pole pieces and a large neodymium magnet which provides remarkable definition. The bridge pickup has been wound with plain enamel magnet wire providing a strong, powerful tone, while the neck and middle pickups have been underwound with heavy formvar magnet wire for a more traditional voice. All three pickups have been crafted for a complimentary tonal offering across all five switch positions. The Cutlass HT shares many of the standard specifications of the original Cutlass guitar, including a contoured Alder body, a roasted figured maple neck, 22 stainless frets, Schaller locking tuners, and Music Man vintage tremolo. The Cutlass HT is available in a Showtime, Brûlée, Midnight Rider, and Raspberry Burst finish.

The Ernie Ball Music Man Stingray HT showcases new custom Music Man pickup technology inspired by over a decade of guitar string research delivering an incredibly dynamic and responsive playing experience. The pickups are able to achieve an ultra-high-output, powerful low-end response while retaining a distinctively clean, clear tone and definition at lower volume control levels. The Stingray HT (Heat Treated) bridge pickup utilizes patent-pending heat-treated pole pieces with a large ceramic magnet and an overwound coil that gives the pickup higher frequency harmonics and excellent touch sensitivity. The custom-wound neck humbucker also features a large ceramic magnet and has been wound specifically to pair with the Stingray's HT bridge pickup. This Stingray HT is outfitted with a stop tail Tune-o-Matic bridge which sets it apart from the Stingray's vintage style tremolo but shares a number of the standard specifications, including a contoured body, a roasted figured maple neck, 22 stainless frets, and Schaller locking tuners. The StingRay HT is available in a Showtime, Brûlée, Midnight Rider, and Raspberry Burst finish. HT Series instruments are available now at authorized Ernie Ball Music Man dealers.

Presets extend the flexibility of an already expansive and easy-to-use reverb.

Intuitive. Great range in all controls. Well-built.

Some digital artifacts at long decay times.

Walrus Audio Slötvå walrusaudio.com

Walrus Audio is a prolific builder, but, as the five reverb pedals in their lineup suggest, they have a real affinity for manipulating time and space. The beauty of the Slötvå reverb (which is derived from the company’s very similar Spin FV-1 chip-based Slö reverb) is how satisfying and simple it makes dramatic shifts between time/space textures.

Slötvå’s big departure from the Slö model is the addition of three presets, enabling quick switches between vastly different reverbs. But Slötvå’s interface is also pretty easily mastered and manipulated on the fly without using presets. And that operational flexibility makes Slötvå just as capable of delivering surprises as predictable, repeatable results.

Slötvå’s three algorithms all range to super-long decay times, especially when you hit and hold the sustain button. “Dark” adds a minus-one-octave signal, rise adds an almost reverse-like swell effect, and dream adds a latch function that effectively “freezes” the reverb signal. In all three modes, the octave content can reveal chorale-style overtones and discernibly digital artifacts at long decay times. Some players love and utilize these sounds to great effect. So, try before you buy if you don’t know where you stand. If you’re untroubled by a little shimmer at expansive settings, however, Slötvå is a fun, intuitive, and performance-practical way to source a genuinely expansive range of unobtrusive to ambient reverb sounds in a compact, easy-to-wrangle unit.
