@Silverdome I understand what you are seeking. You want the sound of the preamp section of an EP-3. I've got an EP-3, an Xotic EP Booster and a Chase Tone Secret Preamp. The Chase Tone Secret Preamp sounds just like the preamp in my vintage EP-3. The Xotic EP Booster, while it sounds really good, does NOT sound the same. Try to find the Chase Tone version. It may be hard to find a used one but as far as I know he is still building new ones. If his turnaround time is too long give me a shout and I may let mine go if you ask really nicely!
