Darkglass Alpha Omega 900 Head
Brutally beautiful sounding 900-watt bass amplifier head, with compressor, 6-band graphic EQ, IR cabinet simulation, and MIDI
The Darkglass Alpha·Omega 900 takes the best elements of Darkglass's most successful distortion preamplifier ever, combined with state of the art features to make a monstrous 900-watt amplifier with earth-shattering tone. While Darkglass' signature Alpha and Omega drive engines add incredible girth and size to the overdriven signal, the studio-grade VCA compressor adds an extra layer of control, and the ultra-quiet 6-band graphic equalizer can help sculpt the tone from aggressive and overdriven to crystal clear clean, whatever your needs may be.
That's not everything though, the MIDI programmability and impulse response cabinet simulation with up to three different storable virtual cabinets make the AO900 not only one of the most complete amplifiers for the touring musician but combined with the auxiliary input and headphone output, the ideal tool for silent practicing.
The Alpha Omega 900 amplifies the best qualities of one of the most powerful and distinct Darkglass products ever made.
Front Panel Features:
Input: Use this jack to connect your instrument via a standard ¼” mono cable
Active/Passive: Use this push-button switch to change from passive to active mode, if your bass is active it can have a hotter signal making the amp to distort early (feel free to use if such additional distortion is desired)
Distortion: Use this push button to turn on or off the Alpha·Omega Engine to add natural compression, organic harmonic enhancement, and saturation ranging from mild overdrive to high gain bass rage
The Alpha·Omega Engine operates before the clean section (you can therefore use the 6-Band Active EQ for additional tone shaping)
Bite: Boosts high mids (2.8 kHz) for additional presence and definition
Growl: Shelving Bass Boost for a fatter tone and increased low end saturation
Compression: This knob controls the amount of dynamic compression added to the Alpha·Omega Engine, the make up gain is adjusted automatically, the compression can be turned off or assigned using the Darkglass Suite

Level: Use this knob to control Alpha·Omega Engine’s output volume
Blend: Use this knob to mix between the Clean signal and the Distortion signal (Alpha·Omega Engine)
Mod: Selects or mixes between the two distinct distortion circuits: Alpha is punchy, tight with a lot of definition, whereas Omega is simply brutal and raw
Gain: Use this knob to change the volume of the signal before the Active 4 Band EQ, you can set it low for ensuring the cleanest operation possible or set it higher for a more aggressive growl
Bass: ±12dB at 80 Hz - use this knob to change the low-end content of the signal
Mids: ±12 dB at 250, 500, 1.5 and 3 kHz. This graphic EQ control the mid content of the signal

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!
I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!
In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.
This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.
Thank you so much! Vintage King has been so fair and easy to work with. I can't thank you enough. It feels good to trust such a hefty purchase to folks who are so helpful and knowledgeable. Vintage King is a sound designers dream store.
You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!
I would recommend Vintage King to any one looking for top-class gear, unbeatable customer service and the best prices on the map!
My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
Thanks for your great service and getting this out today. You guys really are the Kings!
Better than expected! Truly impeccable service. Your team was professional, knowledgeable, provided speedy delivery above and beyond standard. Vintage King Audio is definitely my go to for all of my audio and information needs.
