I currently own several guitars: a 1974 Les Paul Deluxe, a 2004 Mexican Telecaster, a Korean Strat and an 1981 Vantage Flying V clone. I use a home-made cab with two 12" 1966 Oxford 12J4 speakers.
As musical styles go, I play anything from Classic/Progressive Rock to Blues and funk. Much to my surprise, this amp is able to cover all of these genres quite well. The output is fairly clean up to about 10 o'clock on the dial, then the tubes begin to break up. While the distortion is nice at all volumes, it can be a bit "farty" higher up (3 o'clock+), especially using neck pickups.
This head is built impressively. I would have never guessed it was made in China until I looked at the back panel. The construction is very solid; it doesn't rattle or shake even when cranked. When I purchased the EVJ head, I assumed that it would be a good practice amp for home use. Now that I've been playing it for a little while, I won't hesistate to bring it to my next practice session or small gig. It easily can keep up with a drummer at half volume.
I have been playing for roughly 9 years (17 years old) and have owned many different types of guitars, organs, synths, basses etc. Buy this amp. You won't regret it. Some folks turn their nose at 5W heads, but believe me, this is one amp that you'll cherish for years to come.
