I’d like to introduce myself to those in the Electro-Harmonix community that do not already know me. From 1976 to 1981 I was the Manager of Analog Circuit Design for EH, and during that period I designed the electronics for many EH products. I designed the Deluxe Memory Man, Deluxe Electric Mistress, original Polyphase, and many others. More recently I have been a consultant for EH, and have designed or redesigned several EH products now on the market. I am a freelance engineering consultant, and my work is not limited to EH. I engineered the entire line of Pigtronix pedals except for the original EP-1 phaser, now out of production and soon to be replaced by the EP-2. I have also done special engineering projects for such bands as Pink Floyd and ZZ Top.

While engineering is my first priority, I also do repair and modification work. I have lists of the custom mods available for many EH products – just email me and tell me what you are considering having fixed or modded, and I’ll send you the relevant information. I do not work on digital pedals such as the Holy Grail, tube pedals, the Russian-made reissues, or the recent products made with surface-mount components. These are usually more costly to fix or mod than they are worth.

My website http://howard.davis2.home.att.net/ has many informative articles that can give you a better technical understanding of guitar and audio electronics. There’s plenty of practical information there, so check it out. My Terms of Service on that website details the services I offer.

Unfortunately, I usually do not have the time to answer specific “how do I – – ?” questions. There are “do it yourself” sites on which technical questions can be posted for others to reply to.

Keep on ROCKIN!
