It accumulates over the years and I've led so many bands of my own now and forced myself into new situations... You would hope that you play better and better - until you just get too feeble to do it anymore.
I'm better for it and I prefer to keep things simple and see what sounds I can get out of my head and hands rather than relying on a sound that someone else created.
If the guitar synthesizer is really going to stand as a synthesizer on its own, it needs to develop a more characteristic sound; I don' think it's gotten there yet.
I've got four or five records in my head at a time that I try to work on and I would like to do a guitar trio record next - since The Police I've mostly made records with keyboards.
In The Police, in a trio situation - which I've come back to now - it's just so wide open that it does actually provide this arena where you can play with a certain freedom.
