The Bespeco VM14 is designed as a guitar volume pedal but can also be used for other instruments. There are 2 x 6.3mm input jack sockets and 2 x 6.3mm output jack sockets enabling the pedal to run in stereo if required. The base has decent velcro attached if you want to mount this pedal straight onto a pedalboard - this can easily be removed if it's not required.
