An-	info updated 16/2/2010
Analog Brothers	Made since "...1991 in New Hope, Bucks County, PA. USA. Some chassis (metal work only) were produced in Philadelphia, PA. USA, but every other part and assembly was produced in Bucks. Inside every amp on the chassis is a date and my initials (JH). No amp has ever left without that. Serial #s have not been exactly consistent, but our record keeping here has been very good. We have a file on every amp produced and can tell who the original client was, the specific circuit details, the date of manufacture and more info."

Arcane Inc	Custom pick ups made in the USA by Rob Timmons. "I wound my first pickup in 1990 while attending the Roberto-Venn School of Luthiery and since then I have worked for numerous companies in the guitar industry—from large guitar manufacturers to small custom builders like Valley Arts and Tobias—handling everything from running custom shops and artist relations programs to entire guitar divisions. I started Arcane, Inc. with the goal of producing the highest quality, most uncompromised, hand-made pickups in the industry. Since then I have worked with many respected names in the industry. As a consultant, I helped Tyler Guitars founder and namesake Jim Tyler develop the Tyler pickup line, and built the first 500 Tyler pickups myself in the Arcane shop. I also worked on a project with highly respected pickup builder Tom Holmes that eventually became his Japanese line (Prior to the formation of Arcane Inc.). Today I consult guitar companies on pickup design and construction, build pickups on an OEM basis for James Trussart Guitars and also sell to artist musicians and distributors all over the world in search of better tone and the finest in custom pickups. This work is not just a business—it’s a passion. I have a deep understanding of what makes a tonally superior pickup. The products that come out of my shop reflect unparalleled craftsmanship and are the culmination of all the knowledge I have gained from my years of working in the guitar industry.
