I traded my Q-tron for a Maxon AF-9, which I thought would be a interesting thing. Less saucy than I imagined. Yesterday, I went to my guitarshop and they had a musitronics mu-tron. I tested it and was not so thrilled. My question is: should I trade my AF-9 for the mu-tron? or should I start looking for a q-tron? Help!
