Not just for bowed insturements
I play both Violin and Mandolin, and was really happy to find a pickup that works on both instruments without the need for me to modify either of them. On the Mandolin, the pickup fits under the bridge in a space between the feet (given your bridge has that type of architecture. I was fortunate that mine did)
With some Velcro, I am able to move the pickup between instruments easily and effortlessly.
The cord of the pickup sends any movement to the device itself, so be careful when moving around so you don't make extra noises by hitting the cable inadvertently.
One note, this pickup really likes the high ranges, but its nothing a sound board with EQ or post processing can't fix.
