Well what i have right now is a new model X-series Washburn guitar (one with faded skull finish) and a Cube-30 amp. This is the first electric guitar and amp ive ever had, but i feel like i ripped myself off because i originally wanted an Ibanez. Im always regretting things but i feel that i should have spent more time looking around for guitars. Not to say that the Washburn is bad, its just not exactly the best for me i think.

I have some cash to spend, about $300 i think, but im really confused as to what i should get, and some of the people i have asked never really give me any good advice.
What im looking for is a solid Metal sound, and something i can easily play death metal with as well. Ive considered the Metal master, the Metal Zone.. but now im thinking that maybe i should just sell my amp and buy cheap big amp with no settings and get this ME-Boss board. Or i could sell my guitar and potentially get a different guitar. I was thinking about this Digitech whammy pedal but then again a whammy feature is on the ME-boss i think so..
Anyways im pretty lost as to what i should do. any suggestions would be greatly appreciated.
