Who are we

We are couple of easy going players, ampoholics and engineers with master degree in electronics and telecommunication. Amateurs – because we don’t make our livings from music, guitars or amps. Still, quite a few hours have been put into our beloved hobby, including playing, servicing, trading and researching. The owner of fenderguru.com, Jens Mosbergvik has been an author at Premierguitar.com for several years sharing tips and tricks. Jens’ brother Pål is also contributing in the Fender amp side huzzle.
