The third comparison displays the full range of the tone controls, first at minimum, then at maximum, and then back to the noon position. Next comes a gain test: You hear each pedal, first with the gain control at minimum (that is, in full clean-boost mode) and then at maximum.
First, there's a 1:23-long passage with all pedal knobs set to noon. In the audio-only clips you'll hear four audio comparisons arranged into four playlists. For the video I used a 'parts' S-style guitar with Lollar Firebird pickups and Fender-style Carr Skylark.
For the audio-only clips ( see the page at the end of this article) I used a Fender Telecaster Deluxe with Lollar Regal wide-range humbuckers, a clean-toned Carr Telstar amp, and a Royer R-121 ribbon mic, recorded into Logic Pro via a Universal Audio Apollo interface. Aside from switching klones, nothing in the signal chain changes. That way, you hear the identical performance through each pedal.
To keep things as objective as possible, I recorded the demo clips straight into my DAW with no processing, and then re-amped them through each of the klones.
