I've become a bit disappointed in my Mustang GT40 or Katana 50s ability to sound full AND clear at the extremely low volume level that I play at. I used to have a Vox VX II that I remembered was actually better than the GT or Kat at that, and whenever I wanted to jam at the store where I worked, I would plug into the VX I. And I remember that I actually thought that the VX I was better sounding to me than the VX II, 'cause even though it had a smaller speaker and less power, and less bass, it actually sounded less mushy in the bass and mids, and sweeter and clearer at low volume without sounding thin or shrill than the VX II. So, I bought a VX I from SW on Ebay, 'cause then I get free shipping, whereas if I buy it from their website they make me pay for shipping 'cause I'm in Hawaii. And they shipped it to me in two days! I ordered it late Saturday night, they shipped it on Sunday, and it got here on Tuesday. And I love it! I don't need a gazillion amp models and effects, and the 11 amp models that it has cover plenty, and the only effects that I ever really use are a little reverb or delay. And it really does sound brighter and clearer at the low volume that I play at, while still sounding full and sweet, and not thin or shrill. The ported cabinet that's tuned to the speaker to increase bass response, like on a speaker made for stereo or studio use, really makes it sound a lot fuller than just sticking a speaker in a box, like most guitar amps. The Dumble clean setting takes pedals really well, and the Dumble overdrive sounds great on its own, as well. I'm rot really impressed with the Ac30 models, but the Tweed Bassman and Marshall sounds are quite good as well. I haven't tried the higher gain Marshall, Soldano, or MB Rectifier models yet. It doesn't have USB, so there's no computer tweaking like on the VX II, which is fine with me, 'cause I really don't much care for that anyway. Overall, the best amp purchase (for my purposes) I've made in awhile, and the best $100 I've spent in a long time.
