Before you go on and post "Doesn't this EQ/Boost/Overdrive/Distortion Pedal do primarily the same thing as the Eric Clapton Mid Boost Circuit in the Guitar?" or "This has been discussed already!" Please read this original post carefully. I know there's this big discussion from another thread about the alternatives for the EC midboost circuitry. However, the goal for this thread is to discuss the ability to put the ACTUAL EC MIDBOOST CIRCUIT into an expression pedal, and how one may go about successfully putting that in there. I know it may be "possible". There's no question about that, but HOW would you do it? That's the main question of this thread. It's not "well this other pedal works just the same..." Think of it as "Let's build this EC Midboost pedal and see if that is the same as the original. If it doesn't, then it was worth a try since no one else has done it." Got it? Good By the way, i'm not interested in shoving the actual thing into my guitar and calling it quits. That just strays away from the purpose of this thread. THE RESEARCH I've done a fair bit of googling around to see if anyone has ever done this before, but so far I have not found anything. I would love someone to prove me wrong by showing me someone who has actually done it (with some information on how he has done it WITH THE ACTUAL BOOST, NOT A CLONE or anything). So, I am hoping to get some help from anyone who is interested in this little project. THE PLAN-3 pots into 1 (sort of) The thing about this circuitry is that it is made for a guitar with 3 potentiometers in use. An expression pedal only uses 1 of those potentiometers. So the tricky part is knowing how to manage some of those wires to work with 1 pot in a wah. the pedal doesn't need to really have a treble tone cut or a master volume control. We only need to use the midboost tone control.-Active/Passive The other challenge is the minor flaw (if you even call it a flaw) where the EC Circuit will only make the pickups active, and not passive. I'm looking to see if we can use the pedal bypass method to hop over that. But then again, the pedal probably won't make the pickups "active" as it is not within the guitar anymore.-Battery Bypass For the Circuit implemented into the guitar, the battery will engage when the input jack is inserted, and will only disengage when the jack is removed. The expression pedal method should be able to switch off from the battery (or from the AC outlet if that is the preferred method of power) from the same switch as the bypass of the previous paragraph. I think that may be simple. Now for Reference, this is the wiring diagram for the EC Guitar. I'm not sure what to do with the Green and Black (which is to the left of the green) wires. I'm sorry if my capslock seems like yelling to you guys. I'm truly not, haha. It's just to emphasize the point in case people don't want to read this long post. I hope some of you can help me out on this little project! I really admire the help that goes around here in tgp. Let's get movin'!
