What I can say. For the size and price this little speaker rocks. With the Vox AmpPlug 2 this has the character of the Vox amp in a reduced size and of course will never sound like the real thing, but sound and look are looking like the real amp heard on a recording through a small speaker like this mounted in a plastic box. That why I said the character of the real amp, but obviously not the sound. If you just plug a travel acoustic guitar like Harley Benton Traveler-E-Steel, directly without an AmpPlug, you can make a good deal on trips.
When miked it with the AmpPlug2 this definitely rocks on Middle and high ranges. Do not expect too many bass frequencies out of this, but you can make it up on your mixing console.
Considering price both of AmpPlug2 + Little speaker, portability, sound and look, all in all a good purchase that I do not regret at all.
Easy to used. Well presented and delivered at lighting speed by Thomann.
