Hello Abe, you will like the Meyers pick up, note: it sounds best if you can place it near the sound vents or maybe it will work at the end of your Pro37 as it has a sound hole at the end, placing the pick up at the keyboard location will not do much for it. Also I do hope you purchased the one with the goose neck mic as the one with out it will not work for you and is made for more percussion instruments. Try different amplifiers before you choose one as they all vary. take some pictures and let us all know how it worked for you. I use one with my Vibrandoneon and it works great for me.
