Though I still don't know the quality of the silvertone, my new Q (srry about all them) is amp related. buying the ESP would leave me little (maybe $100) for an amp. Can I get a good one for that price, and if not, will that spoil the sound of my good guitar? I might add that I may soon be getting a Boss ML-2 Metal Core Distortion pedal.
My suggestion would be to buy the ESP rather then the Silvertone. Then keep whatever amp you have now, until you can afford something better.
When it comes to Amps that are cheap and affective, I like Hartke, I own a 100 watt head by them, and a 50 watt bass amp. They sound good enough by themself, and if you can get a few pedals, they really scream.
