Yea, I was actually planning on buying an electric (cause that's what would be better for the style I'd like to play). However, money issues come in the way and stuff. Though if things go well, I might get a new one sometime. The one I'm using now is actually my dad's. Though he's never used it much...

All in all, I guess I should probably just try to hammer the note a little harder, as you suggested. I was kind of hoping that I was actually doing something wrong cause hammering it harder than I do it now will most likely be very uncomfortable. Maybe I place my finger badly or something.

Thanks for your help though! I'll go try again.
