Well, I dont know if the OR is the best place to ask if your tone is close to another artists's tone. I dont know who Eric Johnson is, but I though it was a pertty unique tone.

I think you would have better luck in the Tone thread than here.

If you want his exact tone, then research the equipment he used and then buy the same type of stuff.
I finally got my Echoplex Ep-3 today from Ebay!

I tore it apart,cleaned it, and I will demagnetize it tomorrow.

Can't wait to do some recording!!!!
