I have the Tonelab, and I have played with the PodXT on a few occations. Both are great products, but I wouldnt trade my TL for a XT. The TL sounds better to my ears, and the user interface is nothing but brilliant.
Both products need extensive tweaking before they really start to sound fantastic, especially the tonelab comes with horrible user patches.
I can't say that I've given up on a flanger cause I've never liked the effect either. I also can't say the same about Tremolo. I hate them both equally. - Tone2TheBone 2009
