Alright Cab

Cabinet isn't very great sounding on its own. Deep bass tone, but no real versatility as far as tone goes. Low notes on the E and B strings get too muddy for my tastes with this cab by itself. Would not recommend as a standalone rig, but definitely pairs well with the 4x10 that Acoustic offers with it! Definitely more of a "supporter" cab to your rig. Also, the tolex peels off easy on this too similar to the 4x10. Comes with a horn that can turn on or off but can't be adjusted.
