The Prince of Tone, one half of the King of Tone, about half the price of the King of Tone and about 1/100th of the waiting list! I've never played through either pedal. I recorded over an hour of video of myself playing with the pedal for the first and cut it down to under 25 mins of what I feel will be relevant and useful to other guitarists considering a purchase.
Equipment used: Paul Reed Smith 408 and Mesa Express 5:50+. Post recording adds a stereo spread.
