We use Fishman systems as standard ... the reason ? ... they sound great and are extremely reliable
There are a few options to choose from and all are available from Fishman with the Split pick-up.
Matrix 1 + Narrow Split 2.3mm (MAT-NA1 + MAN-LPU) internal with on controls
Ellipse VT + Narrow Split 2.3mm (MAL-EL3 + MAN-LPU) new system with control in the soundhole.
Ellipse Blender + Narrow Split 2.3mm (MAL-EL1 + MAN-LPU) same as above but with a goose-neck mic as well for that 'live' sound.
All of these and complete details at http://www.fishman.com/products/acoustic-guitar-pickups.asp
*note .. the codes I've used are what we use to identify the products with Fishman ... retail codes might differ slightly so always describe what you want clearly !
Hope this helps
