Key Features
Everything Supro makes is raw quality and their accessories are no different. This is the Supro SF4 Blues King Dual Footswitch & Cable set which allows you to engage the gain and boost function on the Supro Blues King.
This is an incredibly well-built and reliable unit. The SF4 will stay with you on the road and never let you down. This also has a detachable cable so if anything was to go awry, it is a simple replacement of a cable instead of having to get a whole new unit.
