I got the AMS-24 to record the output of multi-effect pedals, acoustic guitar pickups, and mics over USB, and it does a great job at that. Audio quality is great, controls are intuitive; it's compact, and has a cool design. I especially like the stereo feature which combines the two mono input channels into a single stereo output - this comes very handy when dealing with upstream delay and reverb. Just make sure you use a Y-splitter cable for the input. I'm very happy with the AMS-24 as it became an indispensible component of my home studio.
