Hi, I'm a great fan of you since the Megadeth's days. Anyway, I'm quite new to electric guitar, about 6 months, but my amp is rather weak one. It's a 15 watt(I think) Yamaha Ga-10, and I planned to get a better one. I like 60's to 80's hard rock/heavy metal style and do you have any idea of getting an amp should I have budget of US 200 - 400? Thanks in advance.
