Headphones, decent volume, and 720p will highlight the differences. I used the same strings so no "OMG it was so much clearer and brighter afterwards" cause by a sting change. [ame=http://www.youtube.com/watch?v=0Zvw4s4vauw]Faber Bridge and Studs (Before, Install, and After) - YouTube[/ame] Its a longer one and for those who can't be bothered yes there was a difference. Top is a segment of the AFTER and the bottom if BEFORE. Even if the Unleash settings weren't spot on the you can see the notes on the top lasting longer. I would describe it as a slowed decay rather than a boost of solid sustain but I still think its a nice upgrade.
