On sale this big box Worm which has wah , vibrato , tremolo and phaser effects and can operate in auto mode (like you would expect) or manual (as a fixed effect that you can only control its range by hand) . It needs 24V adapter . For the European countries I include something compatible (not original) , but other buyers , especially from US/Canada need to buy something locally .

Anyway , it performs well . Small , cosmetic signs of use .
