I've wanted one of these for a few years, and thanks to Sweetwater, I finally have it! The AX50 is a comfortable, lightweight instrument that's surprisingly versatile despite the Spartan control scheme. Between the basswood body, mahogany neck, and rosewood fretboard, one would rightfully assume that it would have a warm, somewhat muddy sound, but the articulation on this beast is unrivaled at ten times the price! It arrived with the truss rod cranked and rear pickup both cranked down, so I had to raise the action (a simple process with the included Allen wrench and a screwdriver to remove and re-install the truss rod cover) and bring the rear pickup up toward the strings, and voila: excellent sound.
The front and rear pickups are the same model: ESP-designed LH-150s. Even considering this, the tonal disparity when cycling between them is massive. The front (bridge) pickup is very hot, with a lot of treble bite, and the rear pickup is much warmer, with more of a P.A.F, sound. Combining the two, the sound is very creamy and smoldering, which is ideal for blues and hard rock. Going back to the rear pickup, you get a sound ideal for clean runs, crunchy rhythm work, and acoustic emulation, then returning to the front pickup, it becomes an all-out shred machine.
Along with the sound is the feel. The contoured heel and slim neck make access across all twenty-four frets easy and intuitive. Of all the Indian rosewood fretboards I've played, this model has the hardest and smoothest, so bends and slides are very comfortable, even considering the oversized frets used. The controls are easy to reach and manipulate in the midst of playing, which makes for a smooth transition between sounds.
All told, it's as simple as this: the AX50 wins. Regardless of the style you play, it will serve you well, so it's worth a try for anyone.
