Sound — 9
I use an Epiphone G-400 SG with stock hummbuckers to play on this amp. I typically play metal music. It is quite loud. The gain is plenty for most styles of music. Like I said earlier, if you're into the very heavy metal, you may want to get an extra boost but you could get by without buying a pedal. On clean, this is the best amp I've heard and for being on clean, I couldn't believe the amount of diversity in the tone you could achieve. I found that the only bit of static I got (barely any) was when I had the gain and treble both on 10. Again it was barely any static.
Overall Impression — 9
Overall this amp gives me goosebumps every time I play it. Whether I'm rippin' an A7X solo or playing some light chord progression, I am impressed. I think this amp could do me for a very long time. The only time I'd ever replace it was if I became a huge rockstar. If it was stolen, I would buy it again used. (not new because I have no money). I think this amp stands up to the rest in terms of tone, sound, and loudness. The only thing I wish it had was a Hellraiser Avenger.
Reliability & Durability — 10
I haven't had this amp for long but I did buy it 3 years used. After these three years, the tubes have not been changed and they still sound great. The amp has no marks on it. After talking with the man I bought it from, he used it for 2 of the 3 years gigging with it with no backup and it never let him down. After 3 years, it has let nobody down.
Features — 9
This amp has loads of features, all the feature the average->above average guitar player would need. It could be used for basically every style of music. My only concern buying it was that there wouldn't be enough gain for me (I play a lot of metal). For me personally, it has all the gain I'll ever need but for those of you looking to play heavy death metal, or styles of music like that, you may want to look into a pedal. Having two inputs is great, lots of fun to be had, and being able to Switch from the clean to lead channel is great! The clean channel is beautiful and clicking the bright button makes it even more enjoyable. The lead channel has a lot of diversity and makes playing solos a lot more fun. I even use the dampening knobs ( resonance, presence) quite a bit. The reverb is pretty good too. I personally use this amp in my bedroom and for the occasional gig. In my room, I can't go past 2 or 3 on the clean channel or 1->2 on the lead channel without my parents screaming at me to turn it down (Lots Of Power). Its a great tube amp. I also use it to play my ipod through with an adapter and it sounds great as long as you leave the ipod without moving it as you will get some fuzz.
