The Vox VFS2A guitar footswitch is made especially for Vox amps. With a high-quality, durable, all-metal construction, this footswitch will stand up to the rigors of the road, and will stay with you for years to come. A 1/4" jack on the VFS2A connects the footswitch to Vox Pathfinder and Cambridge amps. The Vox footswitch also works with the AC custom line of amps and all VR series amps. Includes LEDs to show when either the tremolo or reverb effects are engaged.
