Guitar - SAZ Transducer

Hi guys! Do you know any nice acoustic guitar transducers to record my SAZ. Here is something that I'm working on, but it is recorded with cheap microphone.

I had a Schaller installed on my bouzouki when it was built. The problem with the saz, if it is already built, is that you would need to flush mount it on the soundboard. I like the sound I get with the Schaller: But when recording, I blend it with a live mic, and actually, favor the mic.

Thank you!!! Checking it now :)
