Airis Effects 51-Filthy High Gain Preamp & ORB Power Amp Emulation

This listing is for both the 51 filthy High Gain Preamp Pedal (which has velcro on the bottom) and the ORB Power Amp Simulation pedal. The Orb doesn’t actually pass power to drive  a speaker but rather adds the controls and color of a power amp. One use case for this for example is using something like the included 51 Filthy into IR’s or Cab emulation. In addition to the traditional Depth /Resonance and Presence controls there is also  a midrange control to help fine tune that mid range cut or cut some muddy low end from a particular IR. The 51 Filthy as the name eludes is a high gain preamp that sounds like a 5150 block letter married with a Diezel Hagen. Both are in great working condition Let me know if you have any questions. Manufacturer details below.

51 Filthy

What initially started as one of countless attempts to "improve" the Nemesis Preamp is now the pedal that has been the goal of Airis Effects since day one. A tight, crunchy, articulate, but still saturated and nasty high gain preamp. Something in the realm of a block letter 5150 crossed with a Diezel Hagen. With a classic and simple five control layout (Volume, Gain, Bass, Mids, Treble) there's no learning curve or time wasted fiddling with settings, so you can get straight to the chugs.

Volume: This is the most obvious. It makes the pedal louder. If you're using this pedal as a Preamp going into a dedicated power amp or effects return, its best to turn it all the way down the first time you use it, rather than have your neighbors three doors down surprisingly discover your power amp doesn't have a master volume.

Treble: The classic treble control. The higher you go, the brighter and more attack you'll find. Depending on your speaker and the other pedal settings, going too high can give you what's referred to as "fizz" but certain amounts of this are typically what you want to cut through in a mix. Start low and keep turning it up until you hear the sound you want.

Mid: This could also safely be called a "shape control" as it does the most serious shaping of the overall tone. Take things all the way from a totally scooped 90's solid state head, to the upper mid presence of a 5150, to the warmth of an old Marshall. There's no wrong setting. Just close your eyes and start turning!

Bass: We kept a fairly narrow range on this control to avoid what we would consider "bad" settings. This pedal isn't about huge booming low end, it's about angry high gain tones.

Gain: While you may picture this pedal as being a one-note-pony, it can actually be surprisingly versatile. On the lower end of the dial you will find a light crunchy breakup. A full-on crunch is typical around Noon and above that is where the saturation starts to happen. Going further up, you will get close to maximum saturation at about 3oclock, with the maximum being at maximum. Keep in mind that just like a tube amp, the highest settings will seriously saturate the signal and you will lose some of the apparent "tightness". It's also worth mentioning that these are starting points and not exactly where you will find the setting you're looking for, simply due to the huge variety in pickups, string gauge, playing style, etc. 

The 51-Filthy is designed to be run at 9volts.

heading level 2 THE ORB

A "Secret Sauce" pedal for all your preamps that gives you all the control of the power amp input section from the Lindworm as well as the 51-Filthy Amplifier. Looking for all the control of our power amplifiers without the amplification? Need some more meat and muscle between your preamps and impulse responses? Look no further! That is literally what the ORB specializes in. 

Volume: This is the most obvious. It makes whatever you plug into it louder.

Presence:  This is the same in function to what you would find on any amplifier, but with a handful of differences. Rather than altering the negative feedback loop, this Presence control is a combination of a passive treble bleed and an active eq. 

Resonance: This is also known as Depth depending on what part of the world you live in. It is essentially a low end control for dialing in the thickness/"meat" of your tone. We fine tuned it to help capture some of the "feel" of a thumping 4x12 cab at low volumes. Crank it up and hear how massive your tone gets!

Mids -/+: This is what sets our power amp apart from others. Never again do you have to settle for whatever midrange frequencies are most present in the power amp you've plugged into. Turning this control to Noon will essentially bypass the effect. To the left will cut whatever frequency the Shape control is set to. To the right boosts it. High mids will give you additional presence when boosted. Low mids being cut will clear up any honk/cardboard tone.

Shape: This is the sweep of the range on the Mids -/+ control. Frequency ranges are detailed in the Bull/Beaver Switch section.

Bull/Beaver: This two position toggle switch selects between two independent frequency ranges. Beaver Mode sets the Shape control to a range of 400-800hz. Bull Mode sets the Shape control to a range of 1500-2500hz.

The ORB is designed to be run at 9volts ONLY! Any higher voltage will damage it.
