You may be able to boost the volume from the Neo-D pickup by increasing the individual volume and gain of each effect, this may increase feedback. It is possible to wire the Neo-D to an active preamp but it may be easier to source a higher output pickup. The Fishman Rare Earth Active pickup is a good option, otherwise L.R. Baggs active pickups like the M1 and the M80 will work well.
