Overloud TH-U turns your iOS device into a Guitar and Bass amp simulator, to let you play live, practice or record: standalone and AUv3 included.

Build your own rig by using an unlimited number of amplifiers, cabinets, stompboxes and studio processors in your sound chain. You can connect your guitar to the iOS device using any digital audio interface.

Overloud TH-U includes:
• 86 guitar amplifiers and 4 bass amplifiers
• Official Randall, THD, DVmark and Brunetti models
• 47 guitar cabinets and 2 bass cabinets
• 73 pedal and rack effects
• 1000+ Presets
• 5000+ Captured Rigs

Overloud TH-U includes the Rig Player, the Overloud processor which allows to reproduce captured Amps, Cabs and Rigs.
Several Rig producers already joined TH-U to provide their top quality captured tones, which are now available on iOS too.

The FREE version includes 3 amplifiers, 3 cabinets, 4 stompbox effects, the Rig Player, a master effect section, 18 microphones and a looper.

Sign up to the Overloud account to:
- unlock 17 additional FREE models and Rigs
- get the iOS license of all models and Rigs at a very competitive price if you already own TH-U and Rig Libraries for Desktop

Overloud TH-U for iOS runs the same DSP full processing of the Desktop version for an unprecedented simulation quality.

The AUv3 included format allows you to process your DAW guitar tracks with the full power of the TH-U audio engine.

You can share presets with the Desktop version using the most common cloud services, like iCloud, Dropbox or Google Drive.

Overloud TH-U is stage ready: you can fully control it using any MIDI pedalboard and play with no gaps thanks to the seamless preset change feature.

Overloud TH-U can process your guitar sound while the device is playing a backing track through your preferred App (Music, Youtube, Anytune, …).

Overloud TH-U has a flexible sound chain: you can add any number of effects, change their order with no limitations, and set up parallel chains of effects.

With the Amp Tweak feature, you can customize the amplifiers by changing the preamp and power amp tubes, and simulate the action of a Variac.

The ReSPiRe 2 technology allows you to choose between the real response of the cabinet and a processed version optimized to fit into a mix and avoid frequency overlap with other instruments.

Please fix the Cabinet IR loader 🙏

Awesome app! I bought the full unlock, but the Cabinet IR is not working. It won’t let me load any IRs. I see in the manual that you can load your own IRs in the desktop version. But the iOS version doesn’t seem to be working correctly at themome t. I hope the Cabinet IR will get fixed. Thanks!

Sounds great! Waiting for the next update

I have the desktop version and this app doesn’t disappoint. It sound very much like the desktop version. I’m using an Audient Evo 4 interface with the iPad. I have many of the other popular guitar amp and effects apps and plugins and this is one of the best sounding to me. I would love to give it Five stars, just waiting for improvements in the updates. They said AUv3 is coming soon so I won’t complain about not having it yet. I don’t like the lack of input settings. It seems to do all the input settings automatically, even choosing the audio interface channel? I’m prone to try to turn knobs like on all the other guitar apps, but the knobs are nonfunctional. I find it tedious to have to click on an amp or effect to access it and then use the row of sliders. This slows down trying to make quick adjustments. At least the power buttons work on the effects so I can quickly turn things on and off without going into the menu. Being able to use the same rigs in the rig loader as on the desktop is amazing! This is the best part about the app. I would like to be able to set the sample rate block size. There is no indication that I am at 128, 64, or 32 samples. I can only assume it’s probably 128, or maybe 64. Hoping for many of the other little things to get worked then I would rate this app 5 stars.

The best there is on iPad / iPhone

I’ve been on a bit of a tear lately looking for good guitar tones on iPad / iPhone. I’m a tech nerd as well and love tweaking. I’ve tried a handful of guitar amp sim plugins, and Overloud simply crushes them all. I installed, set up some presets, and it was then I discovered ‘Rig Player’ - and thought ... what is that? For modern guitarists, it’s basically on par with Kemper profiles. While you can’t create rigs yourself with an iPad (that I’m aware of) you can buy many, many rigs. I bought a Marshall-esque pack and was floored. It’s simply amazing how good it sounds and feels. Very responsive and dynamic performance.

I personally use this plugin (thanks for AUv3!) in AUM, as I run a very simple bluetooth MIDI controller, and AUM allows me to run some MIDI processing that further controls my setup. This is the future of guitar processing - and you can run it on the same device you send text messages from. What a time to be a guitarist! Thanks for an amazing plugin.
