Good news first: The ability to load IRs is cool. The main reason I bought this was to use an acoustic guitar IR to spice up the piezo in my PRS, and this worked! Just upload an IR with the app, add some EQ and compressor, and there you go with a usable acoustic sound.
I also liked how the footswitch can be configured to cycle between a set of presets ("songlist mode"). This allows me to cycle between the IR for the piezo, and a clean and a crunch sound for the magnetic pickups. Really nice, and other brands selling tiny modeling pedals should pay a close look here.
I also really liked the effects (but I may not be experienced enough to judge them since normally I play quite dry, with a tiny bit of reverb at most).
And the build quality is really excellent. Unbelievable at this price point, almost!
BUT...
... the first thing I noticed after plugging it in was the huge latency. It is also there in bypass, with all components disabled. It is there on both the analog and digital out. It feels almost like a slap-back delay. It's definitely longer than the 6ms or so that are advertised. It's a lot more latency even compared with my modeling amp from the 2000's I have been playing for decades now. I find that quite irritating.
In direct comparison with some plugins on my PC I also found that the pedal is lacking dynamics. All amps sound quite compressed, even the clean ones, even when everything else in the chain (except the cab) is disabled.
Further, most amp models sound harsh to me. In theory, I can EQ stuff out using the app, besides a ton of other adjustments. But after playing around with it a little I found that quite cumbersome.
Taken together: It's not for me. Great features, but the sound... not so much my taste. What a pity, since I was quite hyped about this pedal after watching all those overenthusiastic youtube videos.
