Why piezo pickup picks up so much noise from, e.g., the left hand sliding up/down the neck? The sound is picked up from balalaika-prima.
I am using the simplest piezo pickup which is placed on the body. I moved it to some different places but the best sound is at the closest position to the bridge.
What is possible solution to pickup more string vibration than noises? To use a pickup which is built into the bridge? Or is the problem in the quality of the pickup?
UPDATE: did experiments as @Unknown said. Placing pickup right under the bridge works fine. Signal to noise ratio has definitely increased, sound has become more clean.
