ChowCentaur is an audio plugin emulation of the renowned Klon Centaur guitar pedal. The emulation features the three knob parameters from the original pedal, along with a bypass switch, and a menu to choose between two different emulation modes. The "Traditional" emulation mode uses traditional circuit modelling techniques, while the "Neural" mode uses a recurrent neural network.

Using this in front of THU fender amp rigs feel so lifelike and expressive it gives me a huge grin and it’s such a great time to be a guitarist with all this emerging iOS sim software. Pure Heaven, thanks! ### 5/5 — Great free AU3 ! *2021-05-01, version 1.3.6* Another very nice AU3 for your iPad outboard. ### 5/5 — Very Niiice! *2021-03-19, version 1.3.6* Sounds great! Good work.

Thanks! ### 5/5 — Make your amp sims ROCK! *2021-03-15, version 1.3.6* Put this in front of your favorite amp simulator and you won’t believe your ears. There is some serious magic inside this app. Whether you want to add just a little growl to your cleans, some bite to your drive or fire to your over driven leads, this will get you there. Can’t wait to see more from this developer! ### 5/5 — Nice But *2021-03-11, version 1.3.3* I like it I was able to get a nice sound for guitar and a nice distortion on a vocal but it did not save my work all settings returned to default after reopening is there something I am missing that is why only a 2 star rating if it saved my work it would be 5 Thank you for the update as I said before I love the sound and now that my settings are saved a 5 star review thank you for a nice sounding and working plugin ### 5/5 — What really great app *2021-03-09, version 1.3.1* Jatin .... many thanks for this gift to the IOS community.
