I have an Ibanez RG that I've had for about eight years now. I tune it down to C and play death metal/black metal stuff. I have an acoustic and I wish I was better at writing music that is slower and more folkish, but I'm self taught for 11 years now and for those first 5 years I mostly listened to fast/heavy metal music. So it's all I find myself playing or writing. My musical taste has broadened tremendously since then, so I wish I was better at writing music for other genres, but I'm only capable of writing metal or generic pop riffs.
