I'm looking to just get an electronic drum kit for fun and practice. Maybe help with some home recording demos with my primary guitar playing. The Roland TD-1DMK with a separate double-bass pedal (like the PDP 502) seems like it fits the bill as cheap but sufficient. My main question is if I get to the point of wanting to cover some metallica or iron maiden (my primary two covers) or even some other prog or neo-classical metal acts, am I going to find I'm missing necessary drums/cymbals? I haven't really found any good source to explain what a minimum drum kit is. Like if you watch portnoy or loble, they're surrounded by a giant cage with like 50 toms and cymbals. Clearly that's overkill for a beginner. But still begs the question, what is the minimum i need to at least cover some prog/neo/classic metal well enough? The double bass pedal is obviously a must. But how many snares, toms, and different types of cymbals do I need? And obviously "minimum" is relative. I could play every metal song by tapping a single spoon on a table if I needed to. It's just a matter of getting 90% there, enough to feel like it sounds close enough and is fun to play. Thanks.
