I have an Ash American Standard Telecaster. It's really not bad out of the box being one of the few I have kept stock. I am really tempted by what I have read about the BG1400. Does it do both clean and overdrive well? How does it compare to a Pearly Gates for Tele or Lil 59 for Tele? I'd like to hear your thoughts. I don't want to just change a pickups blindly.
