01 / The problem

You wanted to play guitar.You opened a DAW.

New project. Add an audio track. Arm it. Find the plugin. Drop the buffer. Mute the channel so you are not hearing yourself twice. Somewhere in there, the reason you picked up the guitar quietly left the room.

02 / The chain

It is already a rig

Gate, drive, amp, cab, delay, reverb, wired in series and ready. Drag the order with the arrows. Every pedal has its own footswitch and its own lamp. Add what you want, remove what you do not.

One of each, in series. No parallel routing, no duplicate delays. A board you could actually build.

03 / The captures

Real amps, captured

Neural Amp Modeler captures are the closest thing to a real amp that runs on a laptop. Raw and open, without the fizz that gives older amp sims away. Load a capture on the Amp pedal, a cab impulse on the Cab, and play.

Browse TONE3000 from inside the app, search, and download straight onto the Amp. Thousands of captures, free, from classic heads to boutique one-offs.

A1 and A2 captures both work.

04 / The audition bench

Stop loading captures one at a time

A tone pack is thirty files of the same amp at different settings. Finding the one you want by opening them one by one is miserable, which is why guides exist just to tell you which file to pick.

Point the Audition bench at the folder. Click any capture and the amp swaps instantly, with your drive, cab, delay and reverb left exactly as they are. Load a DI loop and every capture is judged on identical playing.

Captures carry loudness data and the Amp pedal normalises to it, so you are hearing tone, not whichever file happens to be louder.

The old way

Open a file. Listen. Open the next file. Forget what the last one sounded like.

05 / Practice

Something to play with

Looper

Records after the chain, the way a looper pedal at the end of a real board would. Change your amp capture afterwards and what you already laid down does not change.

Drums

Hosts your actual VST3 kit. Point it at MT Power Drum Kit or Steven Slate or whatever you own, and OHM Rig drives it over the General MIDI map while its own editor stays available for picking kits.

Grooves

Ten drum arrangements that are songs, not loops. Intro, verse, pre-chorus, chorus, bridge, outro, with fills closing every section and a crash on the downbeat after.

Change the tempo and the whole arrangement re-times with the metronome and the tempo synced delay. And there is a recorder, for when something worth keeping happens.

08 / Questions

The things people ask

Is this a plugin? Do I need a DAW?

No. It is a standalone application. You open it and play. There is no project, no session and nothing to save before you start.

What about latency?

On Windows it uses WASAPI Exclusive, which gets you low latency with no extra drivers to install. Set 64 to 128 samples at 48 kHz in the Audio dialog and the top bar shows your real round trip figure while you play, so you are not guessing.

Do I have to buy captures?

No. TONE3000 hosts thousands for free and you can search and download them without leaving the app. Any .nam file works, wherever you got it.

Windows warned me when I ran the installer. Should I be worried?

That warning is SmartScreen, and it appears because the installer is not code signed yet. A signing certificate costs real money every year and this is a free project. Click More info, then Run anyway. The download comes straight from GitHub Releases, so before you run anything you can see the exact file, its size, when it was published and how many people have already installed it. The warning fades as those numbers grow.

Will it work with my interface?

Any interface your operating system can see. If you are on a POD Go, run it in USB audio mode with its own amp and cab blocks bypassed, so you are not stacking two amp sims.

Can I use my own drum sounds?

Yes, three ways. Load your own WAV one-shots, host a VST3 drum instrument, or use the built-in synth kit. In that order of preference.

Is it really free?

Yes.
