It’s pleasing when a device with a little braggadocio in its name lives up to its claim. EarthQuaker’s new Special Cranker is, indeed, special. It’s a warm, ultra-touch-responsive medium-gain overdrive that EQD designed to sound and respond like you’ve added another tube to your amp’s preamp section. The result: The character of your core tone remains vital and intact, but bristles with articulate, controlled snarl and sustain. And if that’s not special enough, there’s also a toggle that lets you switch between germanium and silicon diodes, for two classic flavors of fur.

Recognizing the Speaker

The Special Cranker is an update on the Akron-based company’s out-of-production Speaker Cranker, which had just one knob, labeled “more.” The Special Cranker literally offers more—control, that is, with the addition of an output level control and tone dial that helps shape some of the extra gain on tap, among other things.

The more dial cranks the gain by adjusting the bias of the transistor, and it can be a little noisy when you twist it, but EarthQuaker says that’s normal for this circuit. The level adjusts the output signal and can get pretty outrageous—it seems to double the volume when fully cranked in silicon mode. Unity, for my Zuzu 6-string with coil-splitting, was between 9 and 10 o’clock, so there’s lots of headroom. The tone wrangles treble: more to the right and less to the left, naturally. I found flat response at about 2 o’clock with the Zuzu, which produces Les Paul-like tones in humbucking mode and sounds like a Stratocaster in single-coil settings.

Your core tone remains vital and intact, but bristles with articulate, controlled snarl and sustain.

The circuit board inside is clean, elegantly executed, and home to the pedal’s two flavors of diode. The original Speaker Cranker utilized a single asymmetrical clipping silicon diode. Typically, asymmetrical diode clipping sounds less compressed and clearer than symmetrical clipping. Special Cranker’s switchable silicon and germanium clipping sections, however, enable you to experience two very different flavors of asymmetrical clipping. Germanium clipping, of course, harkens back to the earliest days of fuzz. It is, typically, warmer, darker, and produces less gain than silicon.

Cranking the Cranker

Plugged into a Carr Telstar amp, the Special Cranker is a little demon—especially in silicon mode. With level at noon, more at 2 to 3 o’clock, and tone also at 2 to 3 o’clock, humbuckers produce warm sounds that sustained elegantly, living up to EarthQuaker’s promise of lucid tones. That clarity helps chords flower, while single notes took on a sinuous character and hung in the air—ripe, full, and singing. It was much the same with single-coils, albeit brattier and more snarling. And while the output is aggressive and quite loud, it’s still warmly sculpted and manageable—even with the gain and level turned to maximum.

I’m a germanium fan, but to my surprise I fell hard for Special Cranker’s silicon side. I love gnarly, high-gain germanium tones, but with its medium-gain ambitions, the Special Cranker sounds grittily sophisticated rather than head-rattling. And where the germanium-driven tone had less low-mid content than I’m used to, which was a tad disappointing, the silicon side filled in and fattened the low mids—which I hadn’t expected—creating a robust, blooming sound I adored. The silicon side also made my guitar brighter, bolder, and well-defined, even with extended chords. The rangy tone control is valuable for fine tuning the extra gain and high end (though I was also very happy simply setting it flat). It’s also very helpful when searching for more brightness on the darker, quieter germanium diode.

The Verdict

The Special Cranker is an exceptional medium-gain overdrive with tube-like character, offering plenty of easy-to-control, warm distortion and boost. The germanium side may be too tame for some players. But the silicon side has a full, fat voice that is perfectly responsive to picking technique and preserves the integrity of complex chords. That alone makes the $99 price a bargain. I’d love to see a setting for blending the silicon and germanium diodes, even though that would bump the price. But players looking for a more articulate and colorful alternative to TS and Klon tones should crank up the Special Cranker and tilt an ear.

Some names you’ve heard, others maybe not. But they all have a unique voice on the instrument.

The guitar has been a major factor in so many styles of music over the last 70 years, and any experienced musician can tell you that playing any one of those styles with authenticity takes countless hours of dedication. As we learn the instrument, we seek out music that we find inspiring to help guide us toward our voice. The legends we all know in the guitar pantheon have inspired millions of players. In my musical journey over the years, I’ve always been thrilled to discover unique musicians who never attained the same recognition as their more famous counterparts. With so much music at our disposal these days, I thought this group of guitarists deserved a little more spotlight. The inspiration and knowledge they have provided me were paramount in my development, and I wouldn’t be the player I am without them.

Over the decades with Hüsker Dü, Sugar, and solo, Bob Mould has earned a reputation for visceral performances.

The 15th studio album from the legendary alt-rocker and former Hüsker Dü singer and 6-stringer is a rhythm-guitar record, and a play in three acts, inspired by sweaty, spilled-beer community connection.

Bob Mould wrote his last album, Blue Heart, as a protest record, ahead of the 2020 American election. As a basic rule, protest music works best when it's shared and experienced communally, where it can percolate and manifest in new, exciting disruptions. But 2020 wasn’t exactly a great year for gathering together.

Guitar: The Italian Hybrid

Reader Federico Novelli constructed this hybrid guitar from three layers of pine, courtesy of some old shelves he had laying around.

Through a momentary flash, an amateur Italian luthier envisioned a hybrid design that borrowed elements from his favorite models.

A few years ago, at the beginning of Covid, an idea for a new guitar flashed through my mind. It was a semi-acoustic model with both magnetic and piezo pickups that were mounted on a soundboard that could resonate. It was a nice idea, but I also had to think about how to make it in my tiny cellar without many power tools and using old solid-wood shelves I had available.

I have been playing guitar for 50 years, and I also dabble in luthiery for fun. I have owned a classical guitar, an acoustic guitar, and a Stratocaster, but a jazz guitar was missing from the list. I wanted something that would have more versatility, so the idea of a hybrid semi-acoustic guitar was born.

I started to sketch something on computer-aided design (CAD) software, thinking of a hollowbody design without a center block or sides that needed to be hot-worked with a bending machine. I thought of a construction made of three layers of solid pine wood, individually worked and then glued together in layers, with a single-cutaway body and a glued-in neck.

For the soundboard and back, I used a piece of ash and hand-cut it with a Japanese saw to the proper thickness, so I had two sheets to fit together. Next, I sanded the soundboard and bottom using two striker profiles as sleds and an aluminum box covered in sandpaper to achieve a uniform 3 mm thickness. A huge amount of work, but it didn't cost anything.

“It was a nice idea, but I also had to think about how to make it in my tiny cellar without many electric tools and out of old solid-wood shelves I had available.”

The soundboard has simplified X-bracing, a soundhole with a rosewood edge profile, and an acoustic-style rosewood bridge. For the neck, I used a piece of old furniture with straight grain, shaped it to a Les Paul profile, and added a single-action truss rod. The only new purchase: a cheap Chinese rosewood fretboard.

Then, there was lots of sanding. I worked up to 400-grit, added filler, primer, and transparent nitro varnish, worked the sandpaper up to 1,500-grit, and finally polished.

Our reader and his “Italian job.”

For electronics, I used a Tonerider alnico 2 humbucker pickup and a piezo undersaddle pickup, combined with a modified Shadow preamp that also includes a magnetic pickup input, so you can mix the two sources on a single output. I also installed a bypass switch for power on/off and a direct passive output.

I have to say that I am proud and moderately satisfied both aesthetically and with the sounds it produces, which range from jazz to acoustic and even gypsy jazz. However, I think I will replace the electronics and piezo with Fishman hardware in the future.
