The Pignose Story According to Richard Edlund (Pignose co-inventor)
Wayne Kimbell and I were partners doing graphics and photography for Rock & Roll artist during the '68-'69 era. My friend Warren Zevon was recording his second album at Wally Heider's studio with a Peavey's amp turned up to 11 to get feedback and he was making enemies in nearby sessions. I had seen a 5 watt radio amplifier at Pacific Radio and the idea hit me right there. I made the first Pignose in an English Leather cedar men's cologne box.
At that time we were living in our storefront studio on Melrose Avenue in East Hollywood. Wayne paid for a Copyright attorney and he gave us enough to make about 65 Pignoses. We gave them to some of the most famous musicians of that era, including Led Zeppelin, The Rolling Stones, The Beatles, The Eagles, The Who, and many others.
The first production Pignose model was debuted publicly at the 1973 NAMM Convention in Chicago. Now known as the "Legendary 7-100," the amplifier is still in production today. It has also found a role in many recording studios. It has been used on records by Joe Walsh, Eric Clapton and many more...and as they say rest is history!
That is a great start for the first timer, and if you felling frisky, there is higher power options and speaker combos out there for the next level late night madman experimentation.
Well, it's time for me to get back to the shop.....hopefully this info inspires you to try building your own amplifier, for either a kit or hacked radio body. Homemade amplifiers are a perfect match for cigar box guitars.
