No. I use an old Yamaha DG Stomp. But all multi-effects units are slightly different from each other. The way they organise the patches, the method of programming, the number of presets, the means of controlling patch selection, how many effects can run simultaneously. And all have things that sound better than others. So if you relly can't make up your mind, you should either resign youself to a certain mix of pleasure/disappointment and just grab one, or start collecting individual stompboxes that each do their job to suit your taste.
