Realist Docking Station
Most upright bass pickups (piezo type) do not come with a volume
control. They just usually get plugged straight into the amp
in most cases, or first into some kind of preamp, then on to the
amp. The Docking Station is simply a volume control knob that
attaches (as shown) to the end of the string ball, behind the bass
You can simply attach the Docking Station and plug your pickup
(female) cord into it.
This is much needed and useful in that you won't
have to walk over to your amplifier or preamp to adjust your volume.
It's right there easy to quickly adjust while playing your bass!
