Hey Ian,
I have tried every trick in the book to tame the T3 VH. It just didn't work and kept distorting.
I must say though that I love Rock and the Harmonizer doesn't like it if you sing to high.
The same with my wife (who is by the way a much better singer than me ). Her voice can go pretty high and it so frustrating to have a great KB and crappy vocals.
Now she can sing as high as she wants and the VL2 is right there with her with great vocals. Yeah!
Yamaha has reworked pretty much everything except the VH. So they got to do something with the next model...
