Does anyone know which pickups Chris is using in his current acoustic Martin? It sounds so great, so I really want to know what it is. I think it's something like a Martin Natural Pickup system.

 

I haven't seen the perfect pickup (in my opinion) for an acoustic guitar yet, but the sound that comes out of Chris' Martin is the sound I look for.

All of Coldplay's acoustic guitars live are run through a custom made D/I, so the sound you are hearing is the clean feed from the guitar fed directly to FOH. The actual pickup on the guitar has no effect on the sound from FOH, so even if you get the same guitar/pickup it won't be the same tone without a D/I box and some way to mix it.
