I really love these pedals. Solid, great sound, volume boast and switch-less and I've never even heard Tremonti play, but who ever he is I love his Wah. I've had 3 in the last 2 years and have now given up on all Morley products due to the fact that after 6 Months use the pedal just gets too noisy to use with any gain. I toured Europe and had to play the start of Voodoo Chile with no wah!.
Morley say its because I didn't use their power supply, but mine is far superior to their cheaply made unit and I'm not plugging in more mains supply's when I don't need to. On one I used a battery almost all the time, but had to use my power supply half way through when the power ran out.
I've just brought the Ibanez WD7, so sorry Morley, your pedal is fantastic for 6 Months but has let me down too many times, so farewell.
