SCOT Sean Kelly became the special guest on the set of a new movie starring Steven Seagal - after he designed a special guitar commissioned by the Hollywood action star.

Sean, 42, who runs East Kilbride firm Freshman Guitars, travelled to Canada to hand over the guitar, which took him 10 months to make to the actor's specifications.

The star of films such as Executive Decision and Under Siege was busy shooting the Russian gangster flick Ruslan, in Vancouver, nicknamed North Hollywood because of the number of US films made there.

But when Sean turned up with the guitar, Seagal flipped on seeing it, insisting Sean and his family get the full VIP treatment. Sean revealed: "I was at home one Sunday night when my mobile rang and I was asked if I could take a call from Steven Seagal. "He said 'I have tried one of your guitars. It is probably one of the nicest-sounding guitars I've ever played. Would you make me a guitar to my specification?'"

Seagal, 56, asked Sean to make a replica of a Martin acoustic, which existed before the Second World War but is now extremely rare. Sitting in the sun outside his luxury trailer on the set of Ruslan, the actor said: "I chose the Freshman because they sound so good".

"I was in Scotland last year and everybody said Sean was a good guitarmaker, so I thought I would give one a try.

"It sounded fabulous, so I asked him to make me this one. It's very pretty and it's a guitar I designed. I told him what I wanted and he made it. It's a gorgeous guitar".

"It is special in the sense that we did an exact replica of a pre-war Martin D45, from around 1938. They are just very, very rare."

The 6 ft 4in martial arts expert, who is a seventh-dan black belt in Aikido, asked for the guitar to have the words 'Mojo Priest', Seagal's martial arts name, inlaid in mother of pearl on the 12th fret.

Sean said: "When we got invited into his personal trailer, the first thing Mr Seagal wanted to do before all the airs and graces was to see the guitar. When I took the guitar out the case he just focussed in on the 12th fret. His eyes lit up and I knew it was right. He said it was the best-looking guitar he'd ever seen".

"We'd inlaid Mojo Priest in mother of pearl in the 12th fret. When he saw the guitar he was completely gobsmacked. He then tried it and was completely blown away by the sound. He loved it. He knew we had taken the time to make sure it was right".

"There had been numerous phone calls back and forth, discussing what he wanted, what kind of sound he was looking for. Ten months later, it was finally ready. It is very high spec and is the most expensive guitar we've made. It is also the best sounding guitar we've made. The back and side is made from Brazilian rosewood, which you just can't get any more. We had an offcut which we've been sitting with for 10 years. We use it for special occasions. Then this came up and it fitted the bill."

In Seagal's yet-to-bereleased movie, an ex-Russian mobsterturned-crime novelist, has to confront his past when his family is targeted by violence. Sean and his family got to see Seagal practice his moves, taking out gangsters such as Mikhail, played by Indiana Jones and the Crystal Skull baddie, Igor Jijikine.

"I didn't expect it, but Steven gave us an open invitation to spend the day with him on the set of his new movie," said Sean. "We got to see him perform some action scenes and saw him at work in the editing suite. We also ate with him and were chauffeur driven around the place and back to our hotel. When they were recording some of the fight scenes, he moved so fast. He took the rifle out of a co-actor's hand so fast it was unbelievable. He actually does have the martial arts skills. Of course, I showed him a few moves too."

Seagal explained: "It was great to meet Sean here because music has always been my first love. It is also something I have decided to devote more and more time to".

"I have collected something like 500 guitars. I think I have the most important collection of blues guitars in the world because I have guitars that belonged to every great blues legend. I have guitars that once belonged to Howlin' Wolf, Albert King, BB King and all those guys. I started collecting about 30 years ago. I would play with old blues legends and we would become friends. They would give me one of their guitars and I would give them one of mine, that's how it started."

Seagal, who now spends large parts of the year touring the world with his band Thunderbox, plans to use the new guitar at his next set of gigs. He also hopes that will include a visit to T in the Park next year.

He said: "We're going to be touring and I would love to play at T in the Park. Tell them to invite me. I sure would love to come and play there."

As for that lovingly-made guitar, according to Sean, it is impossible to put a true market value on it.

He said: "The guitar has been valued by a music magazine at £7500 and that is if it wasn't associated with Steven Seagal. So I really don't know the real value of it. The fact that he owns it and that it has his own logo customised on the 12th fret adds to it. I would imagine that puts exceptional value on it".

"The pre-war D45 design is so rare it's unbelievable. He wanted something similar to that in looks".

"Steven has a collection of guitars that is estimated to be worth £2million".

"The insurance on his last tour alone was over a million. When he tried the Freshman heknew we were capable of making a guitar that was special. The exotic wood means the guitar matches someone like him."

Seagal is now one of a growing army of stars endorsing Sean's high-end Freshman guitars.

Even Sir Sean Connery fell in love with a tartan acoustic made by Sean, which is owned by Scots singer Sandi Thom.

Guitar maker Sean said: "We can't match the marketing of the big boys, but people like The Kooks, Kelly Clarkson and Sandi Thom love our guitars and play them at their gigs.

"Having a huge Hollywood legend and artist such as Steven Seagal on board is huge for us. It is the biggest event to date for the company. Now it is onwards and upwards for us."
