Description: "Urla" is an Italian verb which means "scream" in second person imperative (tu, urla = you, scream).

A loud, aggressive and experimental device which consists in 2 effects in 1 pedal unit, the URLA is a CMOS fuzz in front of a synth-based dual resonant filter.

CMOS Fuzz:

A CMOS chip works with digital logic (1, 0).
Compared to the transistor based fuzz circuits (it doesn't matter if germanium or silicon), in a CMOS fuzz there is no "in-between", no "dynamic range", no "vintage tone" or anything like that. There are just 1s and 0s, so no matter which kind of waveshape you put into it: the output will always be square wave with no adjustable gain neither since the square wave is as distorted as it can get.

The URLA obviously makes no exceptions and it provides an overdriven, glitchy and gated fuzz sound with a decay that dies abruptly (but still allowing to sustain each note thanks to a bass boost stage that we put at the very beginning of the signal path).

It offers 2 controls: VOLUME and BLEND.
VOLUME (fuzz)
Adjusts the output level of the fuzz.

BLEND:
As the name suggests, this control allows to blend the fuzz sound with the original signal placed in front of the URLA. Clean guitar tone is probably the most basic example in that sense but no doubt the bravest sonic adventures could find plenty of different as exciting solutions (e.g. as "wall of sounds" enthusiasts, we do love to place a shimmer reverb in front of it or some modulation as well to create different kind of textures). Being a fully analog jFET blend, it goes from almost completely DRY (counterclockwise) to 100% wet signal (clockwise).

DUAL RESONANT FILTER:
This is the second effect placed in the internal signal chain of the URLA and it consists in a faithful replica of the analog filter section of the glorious Korg MS-20, simply our all times favorite vintage monophonic synthesizer.

It's an HIGH PASS filter connected in series with a LOW PASS one, both adjustable with their relative controls of CUTOFF and PEAK. Also, we added a dual potentiometer to control the VOLUME of both, which is pretty useful in order to dial with other output levels in chain (including the internal FUZZ placed in front).

VOLUME: (filter)
Sets the output level of the dual filter.

CUTOFF:
These knobs allow to decide where the frequencies (high ones by LP, low ones by HP) have to be cut. No doubt they're the most exciting controls of the URLA.

We placed those on the external sides of the pedal surface exactly because of that: you'll love messing up with those as much as possible by exploring the wild excursions of both. In fact, depending on the place of their relative PEAK knobs, they can go approximately from 50hz to 15kHz.
Note: since the filters are connected in series (HP into LP), you'll completely mute your signal by turning the LP cutoff fully counterclockwise.

PEAK:
While cutoff allows to remove frequencies (harmonics) from the incoming audio signal, their respective resonance allows to have an additional controlled amplification of that cutoff frequency, creating a secondary peak form and coloring the original pitch.
The resonances of the original Korg MS-20 are well known for their pretty wild and loud nature due their tendency to create a microphonic feedback at extreme settings. URLA makes no exceptions, so USE THESE KNOBS CAREFULLY because they really make your amp scream at high level!

EXPRESSION:
We're not going to lie: if you'll not play the URLA with an expression pedal (by using a TRS cable) to control the cutoff of your favorite filter (HP or LP it's up to you: just place the EXP toggle switch where you prefer), you'll probably miss more than the 90% of the fun.
For that reason, our friend Luca Romanelli from Mastro Valvola (the same guy who wrote the code for the RESPIRA's shimmer) designed an expression input which works correctly with ANY expression pedal on the market.

But there's more: when the expression pedal is plugged into the URLA, you can still set the minimum (the starting point of the parameter you want to control with the expression pedal) by adjusting the relative cutoff knob.

As aggressive as experimental-friendly, URLA is our tribute to all the industrial, noise and alternative artists/records that made our world a better place to live.

Switching System: true bypass managed by soft switch + programmed relay. Power: 9v center negative. Current draw: 100 mA minimum

    Strong legs, somewhat industrial but trendy also
    Size: side table leg
    Good legs, some what utilitarian or industrial, they are strong as they are made out of pipe, and assembly is fairly easy once you get the idea of how it goes together. They are roughly 1.5 feet across maybe a bit less adjustable height on each leg, if you have wood floors you may want to put a pad under each leg as they are full metal pipes. Pretty interesting idea and does not cost much.

    Pretty good, take your time and install it well
    Size: side table leg
    Materials are pretty solid, but once assembled it’s not as sturdy as you would think it should be since the material itself was solid, i say give them a chance, everything out there that’s similar is way over priced

    Heavy duty legs for table.
    Size: side table leg
    Perfect legs for a table I am having made. I have an cottonwood slice. It's heavy and needed something substantial. These are perfect.

    Robust pipe & fittings with a beautiful, smooth black finish
    Size: side table leg
    This set of pipe & fittings for use as low table legs is heavy duty and aesthetically pleasing. Especially when the pieces are handled, the tactile sensation is much nicer than with plumbing steel pipe because this product is beautifully finished smooth. The black pipes are quite smooth as well as the fittings. The pieces are all also pretty robust, though the wall thicknesses are less than in pipe for pressurized water systems. Of course that makes sense as this product does not need to hold fluid pressure. In my view they got the heaviness factor of this product just right; it's not as heavy or robust as black pipe used in natural gas supplies, but still robust and pretty heavy. Assembled, this product is absolutely stiff and unyielding for a solid table that could hold a man's weight easily. The feet utilize a brilliant scheme so that each foot can be independently adjusted for an uneven floor. Thus a level table on an uneven floor is easily accomplished. The feet simply extend the effective leg length by screwing counter-clockwise. To prevent any shifting at the threads adding some pipe compound or teflon tape may be advised. Even masking or duct tape might work as the idea is to just fill any gaps where male threads meet female threads. The four flanges at the tops of the legs provide a wide, solid surface for attaching the table top, with either hidden screws underneath or you could through-bolt a glass table top (provided you have the skill to drill glass!). I think this product would look great with a glass top. Assembly is quick and easy. The hardest part is drilling holes underneath the table top to accept screws. No pipe wrenches are needed as the pieces screw together by hand to an adequate tightness. If any doubt whether they are tightened enough have a strong person with grippy gloves finish. The "X" in the center attaches to the legs with a very clever machine screw system tightened with the included hex wrench. This is presumably because if tightened simply by screwing the fittings, the point of snugness would not likely be where the "T" fittings are exactly vertical. The maker has solved this problem so that you are assured that all legs will be in the perfect vertical position once everything is tight. The setup is also nice and rigid once tightened. This is a huge benefit of steel pipe projects; they are really solid. The black finish is clearly very durable, like a powder coat. It appears that it will provide excellent protection against rust. Coverage is complete; I found no dings or scratches anywhere on any piece. Overall this is a very well-designed product for function and aesthetics. Perfect for a beautifully renovated warehouse condo where an industrial vibe is desired in a rock-solid table that won't shift around. The smoothness of the pipe is top notch. I've used lots of pipe in projects, some of it actual water pipe and some decorative pipe such as this. I've never seen better quality decorative pipe as this maker put in the effort to finish it beautifully smooth. At currently $34.99 I find the price quite reasonable too.
