I had a Yamee and tought it was great until one day when I realized it sucked, well compared to some others TC,and Lexicon are good I use a TC for Chorusing. A Lexicon Vortex for effects morphing (multiple effects with actively changing parameters) Eventide and UREI make some great stuff but hey, you practically have to be able to pull $100 dollar bills out of your _ ss to afford them.
Would you like to buy a vowel?
MORPH!
