*My mistake, on the thread title I actually meant 81X. I have the 81TW in another guitar, but this is the 81X vs 81 in the same guitar* So I recorded a short clip off a single riff. The riff is by the band Judgement (nwright's band) and the song is 21 Grams. https://dl.dropbox.com/u/315457/81v81x.wav I left it a .wav so that the quality is the highest. Same signal chain for both. First 81, then 81X. What do you think?
