According to a new study, you'll be more successful with the ladies if they think you're a musician . . . and you don't even need to PLAY anything for them.

Three different times, researchers sent a good-looking 20-year-old guy to a public place, to approach 100 young women aged 18 to 22, to try to get their phone number.

And each time he carried a different prop, to see how it affected his game. Check out the results . . .

1. When he carried a GUITAR CASE, he was successful 31% of the time.

2. When he had NOTHING in his hands, he was successful 14% of the time . . . less than HALF as successful as the guitar.

3. And when he carried a sports duffel bag, he only got numbers 9% of the time.
