Description

For the Fundamental Series, we challenged ourselves to design a set of pedals with the tonal integrity that’s required to live on a professional’s pedalboard, but with simplified controls friendly enough for even the newest effect pedal users. Each Fundamental pedal includes 3 sliders for tweaking the sound, plus a three-way switch for changing pedal modes. The result is a line of 8 pedals that will keep you covered from your first band practice all the way to a sold-out arena. Designed and assembled at Walrus Audio headquarters in OKC, OK.

  • Thick, affordable fuzz with 2.5 useful modes
Style: Fuzz
I recently bought the Wampler Fundamental Fuzz, excited by the (relatively) affordable price tag and unique control layout. All-in-all, I find it to be a versatile fuzz, with one slight caveat related to the "Gate" mode. BUILD QUALITY/ENCLOSURE: All of the pedals in the new "Fundamental" series share the same build: a sturdy metal box (similar to a compact MXR pedal in size) with three horizontal sliders (!) instead of knobs, a 3-way mod switch, and a soft press bypass switch. It's solidly-built and the sliders felt nicer and more durable than I expected. It is a weird experience at first making adjustments on a linear slider versus a rotary knob, but not in a way that impairs your ability to dial (slide?) in your tone. Strangely, the sliders have a center (50%) notch position, though I guess this is just a tactile equivalent of "setting everything to noon". In terms of longevity, however, I'm definitely going to have to be more careful with storing the pedal. Rotary knobs on a potentiometer shaft aren't invincible, either, but I do feel like the sliders would be more likely to bend or break if other things were thrown on top of the pedal or rammed into it. SOUND QUALITY & MODES: The "Classic" mode is thick and chunky, and it's just an excellent all-around fuzz for chord/rhythm work. It's actually Muff-like, which was a pleasant surprise. There's a nice bassy presence to it, but the Tone knob also allows you to open it up a bit. The "Mid+" mode sounds like basically the same fuzz circuit, but with a dramatic EQ shift that puts it forward in the mix. Volume doesn't go up dramatically between Classic and Mid+, but the latter is going to be perceived as louder because you're pushing those mid frequencies. Both modes excel for both rhythm work and single note leads, and there's a ton of saturated gain on tap. There was a great demo of this video done by The Studio Rats that "sold" me on the pedal, and the guy there got an almost "Eric Johnson" solo tone using one of these modes on a lower tone setting. So, at $99, I think we're already worth the price of admission on those two modes, alone. It doesn't really clean up with the guitar volume knob, though, even with single coils. The "Gate" mode, IMO, is disappointing. I'm not a fuzz expert, but I have played several fuzzes that either feature velcro/gating, or can be set to achieve that effect. These include the DOD Carcosa, EQD Dirt Transmitter, and (recently) the Fender Hammertone Fuzz. All of those do that splatty, gated fuzz effect in a more musical manner than the Gate mode on the Fundamental Fuzz. Walrus acknowledges in their instruction card that there is a volume drop in Gate mode, but it really is quite an extreme volume drop. But the bigger issue I had is that there is no Bias control (and changing the Gain doesn't seem to affect things much). So I was finding that entire notes were disappearing unless you hit them VERY hard, and this was with both single coils and humbuckers. Yes, you can set up a Carcosa or other gated fuzz to behave in the same way, but there's a gray area between "niche musicality" and "unplayable noisemaker", and the Walrus just drifted closer to the latter on Gate mode, in my experience. That issue, aside, the other two fuzz modes are great, and the tone control is excellent! It feels like there's more than just a treble roll-off going on there. The character of the fuzz also changes on lower-half versus upper-half settings, and I could imagine dialing it into a wide variety of amps. It's a great all-around fuzz that doesn't necessarily reinvent the wheel, but may offer a different flavor of that doomy, saturated fuzz sound you know from other classic pedals. ... show more

  • Great Reverb
Style: Reverb
Quality "always on" pedal. My other reverbs are more ambient oriented. This allows for me to add a good classic sounding reverb to my drives without super ambience.

  • True to its name and a little more
Style: Reverb
The Walrus Audio Fundamental Reverb is a solid pedal. Input and output jacks are on the top while the BOSS style 9v power plug is on the left side, for those of you who plan your pedalboards. A straightforward, almost minimalist design and labels makes no guesswork on how to control the three sliders and 3-position slide switch. The “pedal on” light is very bright. I tested this through a Fender Blues Junior. On the spring setting, it sounds very much like the onboard Fender reverb, but with highlighted harmonics. I’d say it almost seems to shimmer more. The hall and plate settings both sound good on the middle of the sliders. The Decay slider changes how long the reverberations continue. The Tone is a tone control, changing the brightness. The Mix is where the magic happens. From the middle position and below is basically like the reverb knob on the amp. Going above the middle pushes the pedal in directions I didn’t anticipate. For the Hall setting particularly, it takes it from feeling like an already large hall to an absolutely enormous canyon. Pushing both the Decay and the Mix to their maximum creates this cavernous sustain that continues even after the pedal is disengaged. To stop this, I switched the 3-position to another setting and the hold stopped. It’s a really nice pedal and I plan to use it instead of the amp onboard reverb for its controllability and variety. ... show more

  • Nice little phaser
Style: Phaser
This is a cool new line from Walrus: U.S.-made pedals in the ballpark of $100 a pop, more than you'd pay for an imported "mini" pedal but certainly in the realm of possibility for your average guitarist. What's more, each entry aims to capture the whole range of a certain type of pedal: Not just a knockoff of one specific circuit, they each contain three modes, with three sliders to adjust the necessary parameters within them (like volume and gain and so on). Each pedal is thus kind of a three-in-one, offering a broad range of interpretations of the type of effect in question. I'm not sure I'm crazy about the use of sliders rather than knobs and toggle switches, but hey, a little variety isn't bad. On to my specific pedal, the phaser. This is part of the same effect family as chorus and flange -- modulation effects where the pedal splits up your sound, messes with it, and mixes it back together. A phaser can add a bit of interest and depth to a clean tone or solo, make a whooshing noise or alien sounds, or impart a metallic layer to a distorted sound. The MXR Phase 90 famously played a part in Van Halen's "brown sound." This pedal is digital and, through its three modes, attempts to reflect all those vibes. The first thing I'd recommend is to experiment with where it goes in your signal chain. A lot of people say modulation pedals should go near the end, but I did NOT get good results putting it in the effects loop -- the pedal took over the whole sound. Putting it before my overdrive, like a wah, sounded way better to my ears. But your rig and ears will vary, so mess around with it if you get poor results at first. But once that was settled I had a blast. The low and medium modes are what you'll use to get "normal" phaser sounds, and I got it to do pretty much everything I was expecting. The "heavy" mode is kind of crazy, especially if you crank the rate and feedback. It's the kind of thing you won't use much but can give you lots of unique "experimental" sounds. If you really want a very specific phaser sound, you might be better off getting the specific pedal it comes from. But this will give you the whole spectrum of phaser sounds in one pedal, which is awesome for those of us who use modulation effects sparingly. Highly recommend. ... show more
