New Interview With Sergio Hamernik of Mercury Magnetics Transformers: Part 2

I have been working with Sergio Hamernik for almost a year now on an exclusive interview all about guitar amp transformers. About two weeks ago I posted Part 1 of the interview. Part 2 has been posted and I think it may be better than Part 1!!

I am a big fan of Mercury Magnetics transformers and have been a dealer for many years now. Their products are excellent as well as their customer service. The Mercury Magnetics line is quite extensive and they will do custom pieces as well.

In this second part of the interview Sergio talks about how transformers affect your amp’s sound and feel, if transformer size matters and how it affects tone, what a choke is and much more information. This is Part 2 of two parts.

Testimonials:
David Nicholas - The 20watt amp is sounding fantastic! Delivered the goods at the gig and I'm finding cool tones all over the place with it. Love the cab w Emenince Tonkerlites too- perfect for my sounds! Makes the 12 string sound like a grand piano!
Peter Lacis - I had an audition for something recently that was all about Led Zeppelin I -- my custom Pennalizer BLEW THE MINDS of the guys I was playing with. They couldn't believe the sounds coming out of that amp. That album was never in my mind when I came up with the idea....so that's yet another testament to the amazing work that you do.
Scott Goldberg - I am very satisfied with the set-up, and the fast turn around.  With the "lower" action it feels easier to play.  I will definitely spread the word.
