Summary: I bought this (in a store) because it can produce a very warm, personal sound that a lot of amps in the same price range can't match. Unfortunately, shortly after purchasing this, I got a "hissing" noise (it almost sounds like a snare rattle) whenever a note or chord was played. Tinkering with the settings would help a little, but nothing seemed to remove it entirely. Please note that this is NOT the typical noise you hear when you turn on any amp.
Excerpt: The sound quality especially for the size of the amp is amazing. You could put on a small concert with this one. Sound responds very well to any playing style. I recommend to not underestimate the sonic power of the system or it could blow your ear drums. So using it in a big open space is recommended.
Summary: I tried the Mustang II and III at home, and the Spider 30 watt in the store and this amp sounded the best. The Mustang III is not really in the same market niche as this Vox 40 watt, it seems more for gigging, and was just too much power for me at home, using it at about 2 on the volume control - it can get really loud! So I went back and tried the Spider 30 - sounded very digital to me on clean amp settings.
Excerpt: Have it a few weeks now and it just has me playing my guitar alot more now! The tones you can get from this are really nice even though I was a little leery of the 10" speaker. sounds great! Models are great. Fx are Ok. Loud, but the adjustable output is great. Good tones @ "bedroom" level and can still blast!
Summary: An amazing amplifier! Good for: Practicing at home, Band Practicing and Stage use(specially if you mic it up) sounds so lound compared to a normal solid state one, i've had it on about twenty watts and it's enough blast through at band practice and on small gigs(indoors) clean channels are quite quiet though if you don't want any distortion a million great sounds and some cool effects, only thing i would change is get rid of some of the factory presets and have more room...
