Yesterday, in a moment of weakness, I decided that I was going to trade my GT-6B in on a Phase 90, Little Big Muff and Nano Baseballs. I sort of forgot why I traded them off in the first place, along with a bunch of other pedals. I was offered $100 for a less than 3 month old unit. I remember being offered $25 for a relatively new $150 DigiTech BP200 in the past. This is because the technologies of the multi-effects change whereas many of the singles are essentially being made the same today as 30 years ago. Technology is less likely to render them obsolete. The morale here: "Be absolutely sure you want a multi-effect before purchasing a new one; keep track of your return window & terms; or purchase used." Having said all of that, I'm glad my deal fell through. My wife reminded me of all the reasons I traded off my singles. That's what I get for surfing the Internet. I'm back in love with the GT-6B.
