DiMarzio Acoustic DP130

This is an affordable contact microphone, with a good enough acoustic sound. I've used this with acoustic guitars, violins, harps, kanteles, etc. and it works well with everything I've used it with. I recommend using it with a preamp, to get adequate volume levels with quieter instruments. The sound is pretty neutral, and the quack usually associated with piezo pickups isn't annoying here. The pickup seems robust enough, and I haven't had any break during all the years I've used them. All in all, this is a good general purpose contact microphone for acoustic instruments.
