got one on a drum machine i just bought (boss dr 110, fact fans) and its sound except there's a loose connection on the headphone jack. works fine with a tiny bit of pressure down when headphones plugged in. the seller's offered me a tenner off and initially i was going to send it back but the thing is ace except for this problem. it's supposed to be an easy fix, just wondering has anyone done anything like this and if so how easy is it? i generally wouldn;t trust myself to do anything like this

Phone up a music shop and ask if they could price for a repair.
