Infinite Low-end Essentials in One Immaculate Pedal

When it comes to bass rig essentials, vital gear can quickly turn into a mess of cables and stompboxes. Darkglass recognized this and met the challenge to create a single piece of gear that could provide all the road essentials yet still be exciting and intuitive. What resulted is the Darkglass Microtubes Infinity, an all-in-one stompbox that’s a versatile preamp/DI, a multi-voiced distortion pedal, a compressor, a tuner, a USB interface, a silent practice rig, and more! With three footswitches, six touch EQ sliders, preset options, and formidable I/O, the Darkglass Microtubes Infinity offers endless tonal possibilities, all rendered in immaculate Darkglass hi-fi that Sweetwater bassists have grown to love. Bassists: this is one formidable pedal you have to check out!

IR, compression, 6-band EQ, and tuner

The Microtubes Infinity lays solid foundations upon which all tone is built. The unit comes pre-loaded with five impulse responses that bottle multiple flavors of iconic bass amps. Sounds can be refined even further with a 6-band graphic EQ that falls at the end of the signal chain. Each EQ slider offers +/-12dB cut or boost, and slider ranges can even be modified in the Darkglass Suite for more extreme control. For keeping tone tight, the Infinity offers a footswitch-controlled compressor. The compressor has five ratios (4:1, 8:1, 12:1, 20:1, and all-in) that can tame even the most absurd levels of input. It even features a user-friendly intelligent make-up gain algorithm to the compressor to make sure output is always usable. And because none of the above matters without a properly tuned bass, the Infinity features a 5-octave chromatic tuner, which can tune any note between A0 and A#5.

Multiple acclaimed distortion circuits

In addition to a clean multiband preamp mode, the Microtubes Infinity also includes several acclaimed Darkglass distortion circuits; there’s Microtubes B3K and Vintage Microtubes distortions in both normal and multiband modes. The Vintage mode offers more additional customization via Darkglass’ coveted ERA control. Dial it down to get the warm ’70s midrange tones or crank it up to get punchy, metallic ’80s and ’90s tones. Distortion is footswitchable, and its placement in your signal chain is even customizable via the Darkglass Suite.

DI preamp and audio interface with ample I/O

The Microtubes Infinity also doubles as an audio interface; whatever your DAW of choice is, whether you use Mac or PC, the Infinity is compatible and can even record in stereo! For max control, the Infinity offers simultaneous recording of your processed and unprocessed signal. Each is recorded to two different tracks, which you can use as affected by the unit or do the heavy lifting in-post using the unprocessed track. And the stompbox offers a full array of rich I/O. There’s balanced L/R stereo outputs, a USB-C, a MIDI in, an XLR direct out, and even a ground lift switch for ensuring a clear signal.

Add your own presets and IRs

Pairing the Infinity with the Darkglass Suite app unlocks truly infinite possibilities. In the Suite, you can create and load IRs, manage presets, and even access advanced settings such as grunt, midboost, highpass, and lowpass filter modes. The IR option is a great way to take the sound of your favorite amp on the road without having to haul massive amounts of gear. Simply create an IR your way, then load it into onto Darkglass Infinity via the Suite for authentic renderings of your favorite amp anytime, anywhere!

Silent practice with aux and Bluetooth

In the spirit of putting the essentials in one box, the Infinity also works as a robust silent practice rig. Plug headphones into the 3.5mm headphone out and no one will ever hear those earthshaking lows. The headphone out features independent volume control, and media playback through the Infinity is also an option using a 3.5mm aux in or Bluetooth from a smart device!

Darkglass Microtubes Infinity Features:

  • Multi-use stompbox — use it as a preamp, a DI, an audio interface, a distortion pedal, compressor, or all of the above!
  • Positive Infinity mode with 5 pre-selected impulse responses (add your own IRs using the Darkglass Suite app)

  • Dual-use footswitches offer both push and rotary operation for fine-tuning settings with ease
  • Stores presets for instant recall of your favorite tones
  • Infinite ways to connect — balanced L/R stereo outputs, USB-C, MIDI, XLR direct out, and a ground lift switch to ensure clear signal
  • 3.5mm aux in and headphone out with volume control for silent practice anywhere you have a power supply
  • Doubles as an audio interface for Mac or PC
  • Additional features and options available via USB/Bluetooth connection to the Darkglass Suite

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

This thing slaps

This thing is bonkers. I knock down a star for the touch sliders. I have small hands and find that they're not responsive all the time, BUT once you get them where you want them you can save them as presets. This is my first time ever using a Darkglass product and I have to say, it did not disappoint.

One point of interest:

I think if you're a compression connoisseur/have very specific compression needs that you may want an additional compressor. I run the Empress bass compressor first at subtler settings and then have additional compression from the Microtubes Infinity.

Shout out to Jon Mosacato my sales engineer!

One stop shop

I've been using this on gigs for the past year, now I'm traveling with it as my stand alone pedal for my tone, and plan on it being my main/only pedal on our upcoming tour. Absolutely great tones, and easy to use. The phone app also makes it super easy to download presets from other users and dial everything in.

Darkglass is the ultimate brand of pedals for Bass!

I was going to pick the ADAM or Infinity, but after hours of listening to videos on the two, I decided to go with the Infinity. Great pedal that is a swiss army knife and fills a lot of rolls.

Incredible Pedal

The tonal possibilities that exist within this pedal are... Well... Infinite. It's truly one of the best pieces of bass gear I've purchased!

FIRE

I owned the AO Photon before purchasing this one. I love the Photon, but something about the Vintage Microtubes just gets my brain going, so I had to get this one. In terms of compression, EQ, noise gate, and cab simming, this works exactly like the Photon. All function great, although one issue I've had is that the touch slide EQ isn't as responsive as the one on my Photon despite being exactly the same. I did purchase a demo model of the Infinity so that may be the root of the issue (which frankly is still concerning for the longevity of the touch EQ because they're not putting it through the ringer as a demo model so it shouldn't be damaged). That being said I'm still giving this 5 stars because I just love it so darn much.
