A man has used his cheapest guitar to shred two would-be thieves, after they broke into his home in the middle of the night and held a knife to his partner's throat.
Two men used mallets to smash down the door to the Truganina home in Melbourne's west about 2am (4am NZT) today, where a 37-year-old man and a 28-year-old woman, were inside.
The invaders demanded the pair hand over the keys to a Mercedes parked outside and put a knife to the woman's throat, the man called Mike has told 3AW.
He went to his office to retrieve the keys but couldn't find them, prompting him to hatch another plan.
"I picked up the cheapest guitar I had, went wheeling out after them, came around the corner, said 'come on boys lets go'," he said today.
"I ran them out of the house and smashed their (car) window in the process."
He said he has about five or six guitars, but chose his bass guitar, because it's an older model he uses less often and has a greater reach.
"They say keep maybe a golf club or something like that, but there's nothing heavier than a guitar at the end of the day."
One of the men was more than six feet tall while the other was shorter, Mike said, with both wearing hoodies.
Police say it's believed a man and woman were waiting in the dark-coloured getaway car in which the attackers fled.
They have appealed for witnesses to come forward.
Mike said his bass guitar has a few scratches but was ultimately still in good condition.
