Begin with the clean sound
Pick one instrument and listen to its clean example first. Notice the attack of each note, how long it rings and where the pauses fall. This gives you a reference before distortion changes the texture. Keep your listening volume comfortable and avoid making decisions from a single loud moment.
Switch without changing the phrase
Switch between Clean, Fuzz and More Fuzz while the same performance continues. Listen to the same part of the phrase each time. Because you are not comparing two different performances, it is easier to concentrate on the change in sound. A fuller or louder example may grab your attention first; return to the clean reference and decide whether the character serves the part.
Rhythm guitar: follow the gaps
With rhythm guitar, pay attention to the spaces between strokes and the separation between notes in a chord. Is the fuzz adding the weight you want, or does a lighter setting leave more room for the rhythm? There is no universal answer: a dense wall of guitar and a sharply defined riff ask for different things.
Lead guitar: listen past the first note
For a lead part, listen to the start, the sustained portion and the end of the note. Then follow a whole phrase. A setting that sounds striking on one held note may feel different across a melody. The Sound Lab is a starting point for choosing which character you want to explore with your own instrument.
Bass: keep the musical role in mind
In the bass examples, listen to the low-note foundation as well as the added edge. Ask what the line needs to do in the arrangement: stay underneath the guitars, become a second melodic voice, or provide a deliberately rough texture. Compare both fuzz settings rather than assuming more distortion will always be the better fit.
Take the comparison into your setup
The recordings are examples of a particular signal chain, not a promise of an identical result through every instrument and amplifier. The Sound Lab displays its recording-chain context. Use the demos to choose a direction, then listen through your own rig. For the hardware controls, connections and image transfer, refer to the pedal manual.
