I've been playing with this amp for about a week now and I'm very satisfied with it! However, I feel that i have to mention a few things about it. For small gigs, home recording, practice and playing it is more than satisfactory. The sound of both channels is excellent (I'm running it through a Harley Benton 2x12 Vertical) and it feels sturdy and high quality. The sound is very nice from the start, meaning you don't have to tweak it much to sound good. The portability is an amazing feature. It works like a practice amp with headphones and the quality is really good. But, if you want it for rehearsals with a full metal band, the volume is not ideal. It is loud but I feel it is not loud enough, even at full volume it gets buried by a 100W tube head, a bass head amp with cabinet and a full drum kit. Many videos on youtube say that it is more than enough to play with a drummer, which is true! BUT, again, with a full metal band (or any other band at high volumes) it will not be satisfactory. Having said that, don't forget that it is a Hybrid 20W amp, so I wouldn't ask it to deliver something that a full 100W tube head would. It us not designed this way. Overall, considering the price, sound and quality I'm extremely satisfied with the Zombie 2 and I believe you will be too. The only down side (for me) is that it is not loud enough for rehearsals with a full band.
