The WaveFunction is a diode-clipping distortion with a difference.
Clipping diodes are the secret sauce in countless overdrive circuits. When a diode pair is configured in inverse polarity, it literally clips off part of each audio wave, spawning distortion. Clipping diodes appeared in such 1960s transistor fuzzes as the Jordan Bosstone. After IC-based distortions arose in the ’70s, they assumed an even more prominent role.
Sometimes they were downstream from the op amp (as in the Pro Co RAT) and sometimes inserted into the op amp’s feedback path (as in the Ibanez Tube Screamer). And they—not tubes alone—generate much of the crunch on a Marshall JCM800.
Different diode types yield different tones, and diode choice is one of the main points of distinction between today’s countless Tube Screamer spinoffs. Germanium diodes sound relatively smooth and soft. Silicon diodes have a rougher, tougher edge. LEDs even more so. Some clever builders incorporate switchable diode combinations, expanding an overdrive pedal’s tonal range.
The WaveFunction Overdrive, from Canada’s Nanolog Audio, is one such device, but with a high-tech twist. While two of its four settings provide conventional germanium and silicon diode clipping, the other two employ a newer form of diode: a “molecular junction,” or as Nanolog Audio dubs it, a “nano molecular sandwich.”
Hold the Mayo
I won’t even pretend to understand how this “sandwich” works, though Nanolog’s Adam J. Bergren has published a scientific paper on the subject. It sure looks different, though! In addition to conventional germanium and silicon diode pairs (1N34As and 1N4148s, respectively), the circuit board includes a small plastic frame. Inside of it is a tiny wafer that looks a bit like a phone’s SIM card. This is home to the molecular junction diodes.
The two “sandwich” settings are impressive. Hear for yourself: My audio clip begins with a guitar phrase repeated through the four diode settings. As expected, the germanium setting is relatively rounded and warm. The silicon diodes are slightly louder and have stronger note attack. The “N1” setting (the first sandwich) is similar to silicon, but a touch fatter. “N2” is the hottest and most aggressive of all. This is something new under the stompbox sun. (FYI, everything’s recorded through a clean combo amp to keep the focus on the pedal’s innate character. Everything gets gnarlier through a hot amp.)

A Familiar Feel
Gee-whiz technology aside, The WaveFunction sounds and behaves much like a conventional IC-based overdrive. The chip is an LM1458 dual op amp. The diodes are downstream, Screamer-style. Judging by ear alone, few players would suspect anything stranger than a well-chosen diode pair. But they’d probably appreciate the two extra-punchy settings, which, despite their aggression, are uncommonly friendly to chords and dissonant intervals.
WaveFunction includes the expected gain and volume controls. More unusual are the dual passive tone controls—to my ear, a huge improvement on a Screamer-style low-pass filter. Low frequencies disproportionately drive amps and distortion pedals. That means the bass-cut control is both a tone control and a gain control. With big bass cuts, tones get brighter and cleaner. Between the double-headed tone stack and the four diode sets, there’s lots of tonal range here.
The WaveFunction lives in a conventional BB-sized enclosure. It has classy metal knobs and board-mounted plastic jacks. The pot shafts are also plastic. A quartet of LEDs indicate the current diode setting. Despite the high-tech diodes, this is a traditional through-hole build, not surface-mount. The pedal runs on standard 9V power and has no battery compartment.
The Verdict
Nanolog’s WaveFunction Overdrive is both familiar and fresh. In many respects it’s a conventional IC-based overdrive. But its modernistic diodes generate fat, aggressive clipping. Meanwhile, the added bass-cut pot yields colors you won’t get from a Screamer-style tone control. This is a good-sounding overdrive in its own right—and perhaps a foretaste of cool things to come.

Loopers can be complex enough to make beginners cry. They are fun if you have time to venture for whole weeks down a rabbit hole. But a looper that bridges the functionality and ease-of-use gap between the simplest and most maniacal ones can be a sweet spot for newbies and seasoned performers both. The JamMan Solo HD lives squarely in that zone. It also offers super-high sound quality and storage options, and capacity that would fit the needs of most pros—all in a stomp just millimeters larger than a Boss pedal.
Fast Out of the Blocks
Assuming you’ve used some kind of rudimentary looper before, there’s pretty decent odds you’ll sort out the basic functionality of this one with a couple of exploratory clicks of the footswitch. That’s unless you’ve failed to turn down the rhythm-level knob, in which case you’ll be scrambling for the quick start guide to figure out why there is a drum machine blaring from your amp. The Solo HD comes loaded with rhythm tracks that are actually really fun to use and invaluable for practice. In the course of casually exploring these, I found them engaging and vibey enough to be lured into crafting expansive dub reggae jams, thrashing punk riffs, and lo-fi cumbias. Removing these tracks from a given loop is just a matter of turning the rhythm volume to zero. You can also create your own guide rhythms with various percussion sounds.
Backing tracks aside, creating loops on the Solo HD involves a common single-click-to-record, double-click-to-stop footswitch sequence. Recording an overdub takes another single click, and you hold the footswitch down to erase a loop. Storing a loop requires a simple press-and-hold of the store switch. The sizable latching footswitch, which looks and feels quite like those on Boss pedals, is forgiving and accurate. This has always been a strength of JamMan loopers, and though I’m not completely certain why, it means I screw up the timing of my loops a lot less.
Many players will be satisfied with how easy this functionality is and explore little more of the Solo HD’s capabilities. And why not? The storage capacity—up to 35 minutes of loops and 10 minutes for individual loops—is enough that you can craft a minor prog-rock suite from these humble beginnings. Depending on how economical your loops are, you can use all or most of the 200 available memory locations built into the Solo HD. But you can also add another 200 with an SD/SDHC card.Deeper into Dubs
Loopers have always been more than performance and practice tools for me. I have old multitrack demos that still live in the memory banks of my oldest loopers. And just as with any demos, the sounds you create with the Solo HD may be tough to top or duplicate, which can mean a loop becomes the foundation of a whole recorded song. The Solo HD’s tempo and reverse features, which can completely mutate a loop, make this situation even more likely. The tempo function raises or lowers the BPM without changing the pitch of the loop. As a practice tool, this is invaluable for learning a solo at a slower clip. But drastically altered tempos can also help create entirely new moods for a musical passage without altering a favorite key to sing or play in. Some of these alterations reveal riffs and hooks within riffs and hooks, from which I would happily build a whole finished work. The reverse function is similarly inspiring and a source of unusual textures that can be the foundation for a more complex piece.
HD, of course, stands for high definition. And the Solo HD’s capacity for accurate, dense, and detail-rich stacks of loops means you can build complex musical weaves highlighting the interaction between overtones or timbre differences among other effects in your chain. I can’t remember the last time I felt like a looper’s audio resolution was really lacking. But the improved quality here lends itself to using the Solo HD as a song-arranging tool—and, again, as a recording asset, if you want a looped idea to form the backbone of a recording.
The Verdict
With a looper, smooth workflow is everything. And though it takes practice and some concentration in the early going to extract the most from the Solo HD’s substantial feature set, it is, ultimately, a very intuitive instrument that will not just smooth the use of loops in performance, but extend and enhance its ability as a right-brain-oriented driver of composition and creation.
The Warm Bender dishes these sounds with ease and savage aplomb. Outwardly, it honors the original MkII—a good way to go given that the original Sola Sound unit is one the most stylish effects ever built. But the 3-transistor NOS 75 MkII is only one of the Warm Bender’s personalities. You can also switch to a 2-transistor NOS 76 circuit, aka the Tone Bender MkI. There’s also a silicon 3-transistor Tone Bender circuit, a twist explored by several modern boutique builders. Each of these three voices can be altered further by the crown-mounted sag switch, which starves the circuit of voltage, reducing power from 9 to 6 volts. From these three circuits, the Warm Bender conjures voices that are smooth, responsive, ragged, mean, mangled, clear, and positively fried.
The Compact Wedge Edge
Warm Audio, quite wisely, did not put the Warm Bender in an authentically, full-size Tone Bender enclosure, which would gobble a lot of floor space. But this smaller, approximately 2/3-scale version, complete with a Hammerite finish, looks nearly as hip. It’s sturdy, too. The footswitch and jacks are affixed directly to the substantial enclosure entirely apart from the independently mounted through-hole circuit board, which, for containing three circuits rather than one, is larger and more densely populated than the matchbox-sized circuit boards in a ’60s Tone Bender. Despite the more cramped quarters, there’s still room for a 9V battery if you choose to run it that way. Topside, there’s not much to the Warm Bender. There’s a chicken-head knob for output volume, another for gain, and a third that switches between the NOS 76, NOS 75, and silicon modes. Even the most boneheaded punk could figure this thing out.
A Fuzz Epic in Three Parts
Most Warm Bender customers will find their way to the pedal via MkII lust. If you arrive here by that route you won’t be disappointed. The Warm Bender’s NOS 75 setting delivers all the glam-y, proto-metal, heavy filth you could ask for. It sounded every bit as satisfying as my own favorite MkII clone save for a hint of extra compression that falls well within the bounds of normal vintage fuzz variation. My guess is that when you’re ripping through “Dazed and Confused” you won’t give a hoot.
“There’s more color and air in the NOS 76 mode.”
If the NOS 75 circuit suffers by comparison to anything, it’s the 2-transistor friend next door, the NOS 76. The lower-gain NOS 76 mode is, to my ears, the most appealing of the three. It’s the most dynamic in terms of touch response and guitar volume attenuation and delivers the clearest clean tones when you use either technique. There’s more color and air in the NOS 76 mode, too. Paired with a neck-position single-coil, it’s an excellent alternative for Hendrix and Eddie Hazel low-gain mellow fuzz that’s more like dirty overdrive. The silicon mode, meanwhile, lives on the modern borderlands of the ’60s-fuzz spectrum. It’s super-aggressive and focused, which can be really useful depending on the setting, but lo-fi, spitty, and weird when starved of voltage via the sag switch. It’s deviant-sounding stuff, but extends the Warm Bender’s performance envelope in useful ways, particularly if you hunt for unique fuzz tones in the studio.
There’s a widely accepted bit of wisdom that says most germanium fuzzes sound lousy unless you turn up everything all the way and use your guitar controls to tailor the tone. This is partly true, especially with a Fuzz Face. But in general, I respectfully disagree and present the Warm Bender as exhibit A in this defense. The gain and volume controls both have considerable range and fascinating shades of fuzz within that can still rise above the din of a raging band.
The Verdict
Some potential customers might balk at the notion of a $199 vintage-style fuzz made in China—no matter how cool it looks. But the Warm Bender looks and feels well made. The sound and tactile sensations in the three circuits are truly different enough to be three individual effects, and $199 for three fuzz pedals is a sweet deal—particularly when consolidated in a stompbox that looks this cool. There is a lot of variation in old Tone Benders, and how these takes on the circuits compare to your idea of true vintage Tone Bender sound will be subjective. But I heard the essence of both the MkI and MkII here very clearly and would have no qualms about using the Warm Bender in a session that called for an extra-authentic mid-’60s fuzz texture.
