I like the pedals that are made of more metal than plastic. Boss and Digitech are most common and fairly good. Zoom, when theyfirst came out were not very good. things have changed.
once a stomp box gets in the 200$ range expect more effect and reliability.
eventually, you may want to look into boutique pedals. I had Analogman modify my Tubescreamer. it is an awesome pedal now.
he has an informative web site. www.analogman.com
