If you can throw $400 for a pedal board , get the Boss GT-6 ... If not , any cheap unit will make you learn about what effects you need and don't need , in other words , put you on the road , so that you'll know where your money goes right next time ... Paying a 100 bucks to put yourself on the road isn't a waste of money IMHO.

A nice and cheap unit would be Digitech rp-100 or something similar ... If someone at the store tried to sell you a Zoom , instantly "stuff it" in his/her hole!
