Our Description

Our Description

The ST9 Personal Studio is a small amplifier, small enough to fit into a shirt pocket, which offers a choice of “clean” or echo-enhanced sound. It lets you hear your own playing at the volume you are accustomed to, to prevent any over-blowing. An Aux In is a direct line-in for playing along with CDs or other recordings. Works perfectly with the Yamaha MC7 pick-up microphone.

You may need additional cables to attach the ST9 to the line-in on your amplifier. The output on the ST9 is a 3.5mm stereo jack, so we suggest a 3.5mm stereo to 2 x phono cable.
