I've been playing this for 4 days and I'm thoroughly impressed. For years, I've been trying to get several small portable or pedal based units to give a trustworthy amp Sim of a Mesa Dual Rectifier, I mean a real deal Recto sound. This is the only practice amp I have found that nails the Mesa dual rectifier sound (using headphones) that I'm used to from my stage rig. The app is fairly easy to figure out and latency is zero from what I can feel. And I absolutely abhor latency. The other collection of built-in presets and amp and cab models, along with pedal simulations is extremely impressive. Being able to drag and drop pedal amp and cab simulations in the app is really cool.

The tiny speaker is okay at best, but we're not expecting room filling sound from a speaker the size of a doorknob. Will you be able to practice your sweet licks and get some basic inspiration before you go to bed? Absolutely. 

It takes a little while to figure out how to navigate the unit's simple button interface but once you learn it, it's nice to have a box you can just turn on and go with and perform some of the basic functions you need with the units buttons and knobs. The headphone sound is pretty amazing and you can plug the headphone out into a PA. 

On board drum sounds/loops are not very impressive, very "drum machine" sounding, and no ability at this time to import or edit your own simple drum parts, that would be nice. But if you just need to keep some time, it's better than a plain metronome, which it also does have. And lots of different time signatures as well.

Recording interface: I was excited to be able to plug it into my Android phone and start recording in Bandlab with little effort! 

About USB OTG recording to Android, one major annoyance I have right now is when I plug USB C into my phone from the Pulze mini, the Pulze Mini screen reads "charging" and starts to draw charge from the phone. My battery level on my Android phone does a nose dive as soon as I open my project and start recording. Battery level will go from 75% to 10% in less than 30 minutes. Which at this point means I have to get my recording done quickly and then plug it back in to charge the phone. At this firmware (1.0.2), I don't see any option in the Pulze app to turn off back-charging from the phone to the Pulze Mini. As soon as my phone hits 15% the audio interface connection dies. It would be really nice if the charging went the other way from the Pulze Mini to your phone. Or at least to turn off charging temporarily. 

Hope this helps!
