Overloud THU turns your iOS device into a Guitar and Bass processor. NEW! Centuria Model. 40% OFF Premium pack

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, with IR Loader 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.

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.

Fantastic Amp/FX suite w AUv3

Downloaded the free app to trial it on iPad Pro, with high hopes and a willingness to adopt if it was useful. Although there were initial disappointments, they have all been ironed out over the last few months and I can safely say that with AUv3, frequent updates, fixes and new amp packs available this is now the premiere all-in-one solution for iOS guitarists — especially who use a host/DAW.

The raw amp sims sound great and very usable. FX are abundant — though I personally find the layout a little clunky. Still, it’s highly programable and the quality is excellent. Also very nice to have the same platform for desktop and iOS.

iConnectivity iConnectAUDIO4+ support has now been added by the developers which I’m very grateful for.

Developer Response ,

Hello Vaultnaemsae, if you can contact Overloud tech support, we will be able to investigate your issue with the audio interface.
AUv3 is on our roadmap and will be released soon as an update.

The best sounding amp sim on iOS.

I don’t know how Bias is popular, but it sounds like a toy compared to this. I know these guys have been in the amp sim game for a while, and they know how to make it sound and feel inspiring to play. The stereo routing and especially AUv3 support make this dominate anything else. I don’t mind the slider based ui since I got used to it since fake knobs are fiddly. The main request would be a an auto mute when changing interfaces. That would help eliminate feedback when you unplug your interface and forget to mute. Also, the looper needs some work. Otherwise, keep up the great work!
