The software is Ok, the branding is a bit much

Yeah... There are much better modeling apps out there, but this one does do AUv3, so that is a bonus. Nonetheless, this dev’s apps are usually rather good...

However, this developer’s religious branding will prevent any further purchases from me.

Might be 5-Stars - we’ll see!

I’m writing this now rather than after more extensive use because of the reviewer who gave it a one star and who is obviously penalizing the developer for his/her own incompetence. Of course it works! It works great!

So far, I’ve liked just about everything in this FX suite. I can’t honestly give it five stars when I’ve only used it for a few days. But so far I’m very happy.

The included modulations such as chorus sound as good as any I’ve used on iOS, with guitar at least. The included basic spring reverb is especially nice for guitar ... not because it sounds especially like a spring reverb, but because it just plain sounds good. The included preamp sounds pretty good as long as you follow with a cabinet simulator IR - or possibly if you use one of the IAP amp sims. I haven’t given those a run for the money yet. The wah has some good sounds to be found, with enough tweaking. The overdrive sounds really good (though I think I prefer a more TS-9 flavor most times).

So? Don’t listen to the chump who can’t get it working. It works and sounds great. At least 4 stars great. Maybe 5. Will update after I have some more miles on it.

Amazing sounds! Fantastic sound fox app!

This auv3 effects app has a really outstanding set of sounds and is really fun to use! I really appreciate the fair pricing for the in app bundle purchase. The fair pricing along with the quality of the sound effects included shows the commitment of the developer to deliver quality products. For the poor review that was given by a buyer, first you have to know the basics of how to use these auv3 sound effect apps. Seriously is not that complicated, buy AUM load a sound app or plug your guitar, and then load this app as an effect. Is this that complicated to understand? Plenty of videos online as well.
