I can't believe no one has mentioned Roger Mayer effects. If you want the wah that recreates the sound you have buzzing around in your head right now...Roger Mayer is the source you have to follow. Satriani, Hammet and everyone else that has that great wah sound you here on all your favorite recordings... A+ you guessed it roger mayer...It makes the vox, crybaby, even the budha, sound like toys, $150 for a wah that sounds better, did i mention it is a gillion times more comfortable to play... a true preamp even... try it I guarantee you'll never use another wah again
