The Show Me the Way hitmaker reveals he wanted to help promote the initiative because he is convinced other musicians will benefit greatly from the device, which allows players to change tuning in seconds without having to switch instruments.

The AxCent Tuning Systems gadget currently sells for around $400 (£250), but bosses want to find a way to produce and market a cheaper version for the wider public.

Frampton tells, "This is one of the very few things that I would actually get involved in to go and raise some (funds) because I've used it for many years and actually believe in it... It's incredibly precise. It's never failed me."

To boost interest in the campaign, Frampton has agreed to offer up a number of rewards in exchange for sizeable donations. The prizes range from signed memorabilia and concert tickets to a signed Gibson guitar and flight and hotel costs to attend one of his future tour dates.

He jokes, "I think you actually get to sleep with me. Well, no you don't. I'm sure there's one in there for that, but we don't have a price worked out yet!"

The new project was launched on this week (begs08Jun15) and had already raised 25 per cent of its goal as WENN went to press.

Other rockers who rely on the handy equipment include The Who's Pete Townshend, Eddie Van Halen and Graham Nash.
