Joe, Perhaps you might try an isolation transformer or an impedance transformer between your EDP and amp. I know that both ART and Ebtech make such a device and they are inexpensive, and might cure what sounds to me like impedance miss-matching.

One issue that has gone around a few times on this list is that of gain staging in the EDP. I've held a few different opinions on that issue over the years and presently think there is still a problem there (a caveat being that my sample group consists of my 2 older model beige face Oberheim EDPs). Being more of an old-school-guitar-into-tube amp-equals-tone type guy, I've struggled off and on with my EDPs as tone-suck culprits. Here's the issue as I see it: A large part of the sound I want to hear is the sound of my amp "breaking up" as my guitar signal hits the preamp stage of a Fender tube amp. Any pedals that change the way that signal hits the amp are going to change the tone. When going through an EDP, I have met an unwinnable fight in trying to balance the loss of gain through the EDP vs. the noise produced by the EDP. Through proper gain staging (setting of input and output levels on the EDP), I can minimize the problem, but not make it disappear. I do not feel it is possible to simultaneously A) not distort the input, B) have a quiet loop with no hiss added by the EDP, and C) still have a full gain signal hit the amp. I can get the loop hiss under control, but there goes my amp tone. I can get the amp screaming, but either deal with hiss or digital distortion, depending on whether I'm leaning towards the input or output of the EDP. Loopers who are not concerned with old-school tube amp tone issues probably don't care about this issue. If you have an amp modeler or something BEFORE the EDP and are then going into a super clean power amp just to amplify your signal, you may never even notice this. But if you are trying to use the tone of your amp as a big part of your sound (like most guitar sounds from the 1940's through the present), the EDP can be frustrating. Don't get me wrong. I still love my EDPs. They are an amazing tool. This is just one thing to think about.
