My initial experience was rather inspiring. Disappointing, actually. Lots of overly processed - and yes, artificial - sounds that in no way bettered my old stand-bye Lounge Lizard. In fact, they sounded worse.
Until I stumbled on the GT Vibro Wurli presets, and my mind changed entirely. This is a traditional, dry sound that I immediately fell in love with. Warm, intimate and playable - just what I look for in a Wurli.
I then began to tweak and explore, and found out just how far you can take the basic tones.
Interestingly, I actually found that presets obscure the fact that this generates some excellent classic tones. Most importantly, I dropped them into some tracks and they sit wonderfully.
I have to say I'm very tempted.
