I am thoroughly impressed with the Mooer Prime p1! This will prove to be an indispensable tool for me. It has so many possible uses and simply sounds really amazing. I can use it as an entire rig (electric guitar, bass guitar, or acoustic electric) straight into my computer’s recording interface via 1/4” cable. I have also tried it in front of a traditional amp for using the dynamics, overdrive pedals, or even some of the modulation effects. I also like the results using it in the fx loop of the amp (after the preamp and before the power amp), getting some cool delay, reverb, and modulation after the preamp. And of course it could be used right into a PA at a live show. Or play it into headphones. What a useful tool! I really love that I can use it for not only electric guitar but bass and acoustic-electric as well. I think the Prime p1’s preamps and cabinet simulations sound fantastic, and there are a plethora to choose from. All of the effects sound great and can be arranged in whatever order you like. The iOS/Android app is very easy to use and connects to the Prime p1 via Bluetooth seamlessly. Within the app, you’ll have complete control over your setup and presets, and there are some other handy tools, like the looper, tuner, and drum machine. There is also direct recording into a mobile device via USB (haven’t tried that yet, but maybe I’ll use that feature one day as well). Be sure that your Prime p1 is on the latest firmware (go to “P1”, then “Settings,” scroll to bottom). The Prime p1 is a fantastic device that I would recommend to any guitarist or bassist.
