An Amp For All Spaces

People create and record music everywhere these days – in small studios, apartments, even bedrooms. A lot of those places aren’t great for big amps; they take up a lot of space and only sound really good when you crank ’em up loud. Small amps have been used to great effect, in sessions by Jimi Hendrix, Brian May, Eric Clapton, and Frank Zappa, to get unquestionably distinctive guitar tones. The Audity One takes that idea to versatile extremes for recording.

Made For Musicians. . .

Everything about this amplifier, from the tube placement to the power connector, was carefully considered to serve the purpose of creating a truly useful amplifier for just about any recording environment. Ready to rock? Connect your favorite 8-ohm speaker (rated 15W or more) and enjoy the pure tube tone. Not a good time to make noise? Turn the speaker off, plug it into your audio interface or mixer via the transformer-balanced +4dBu line output, and keep playing till dawn. Plug headphones right in the line out jack if you want. It also comes with our Handy Footswitch™, which serves the same purpose as the footswitch without the foot part (or the cord part) – you plug it into the ‘fs’ jack and the tremolo effect comes on; pull it out and it’s off again.

. . .But Not Just For Guitars

The Audity is also an instrument tube preamp. Use it in the studio to record bass, mono synths, re-amp tracks, run it as a tube overdrive effect, switch to unbalanced output and use the Audity to drive a bigger amp, and much more. Bypass the tone circuit for pure tube preamplification. Use it with a cabinet in small or medium-sized venues for guitar with the speaker on, or turn the speaker off and use the output as a tube DI for any instrument with line level output — just set the volume knob at 12 o’clock and go from there.

From Clean to Saturate

The normal channel on the Audity One will give you a range of tones from clean to tube overdriven. Switch on the ‘od’ channel – for overdrive – and get another level of gain entirely. Push past overdrive to distortion and even further into saturation, if that’s your thing. Mic it up, plug it into another amp and use it like a real tube overdrive pedal (or both) – perhaps you can see the endless amount of tonal choices you might have here.

The Most Important Part: Quality

Our amps are hand-built in Newburgh, Indiana, USA. Everything is wired point-to-point, using 1% tolerance metal film resistors and 5% tolerance Orange Drop® capacitors in the audio path. The power supply transformer is custom wound to our exact specifications. The IEC connector that connects the AC plug has EMI and RF filtering built into it. We check the operating voltages and give every amp our 24-hour performance test before it leaves the shop.

You Want Orange Knobs? We Got Orange Knobs

Yes, you can customize the look of your Audity One, down to the knobs. Standard choices include multiple chassis colors, knob colors, and jewel colors. There are also custom chassis colors available, and coming soon: custom circuitry options.

An Amp You Can Roll With In More Ways Than One

The size of the Audity One Recording Amplifier Head makes it easy to transport to your next session. It also leaves you room to bring along more tubes and try some extreme tube rolling. Our custom wired power transformer makes it possible to try not just different brands of the same type of tube, but actual different tube types in the preamp, power tube, and rectifier socket. You can roll tubes until you dial in the exact tone and sensitivity you need. Instead of a 12AX7, dial back the gain with a 12AT7 or even 12AU7 in the preamp. Switch the 6BQ5 for a 8BQ5 as the power tube for a darker tone, or expand the headroom with a 7189. Our durable power supply works with current-production 6CA4 rectifier tubes (and of course new old stock 6CA4s and also 6V4s), so rectifier tubes are inexpensive and easy to find. All-in-all, the tonal possibilities are well beyond what you would normally expect from just about any instrument amplifier.

The Curious Audity One Recording Amplifier sounds great, looks cool, and has a ton of functionality. It’s a recording tool for everywhere from your control room to your bedroom.
