The Seiko STM30 Pickup Microphone is a huge improvement on its predecessor, the STM20, as its connecting point is a whopping seven times stronger! The STM30 plugs into the Line-In socket of your regular tuner and then simply clips on to your instrument to enable you to tune directly via the vibrations in the instrument’s body – meaning it is not affected by the sound of other instruments or noise. For example, you can tune an electric guitar, during a performance, without even plugging it in!
