I've got a Yamaha DG80 112 from 1999, and a DG130 head from 2000. Their 20 bit resolution is antique by today's standards, but back then 16 bit was state of the art, so they were ahead of their time. A friend of mine who dabbles in electronics told me that he was impressed by their robust construction, and he is an avowed modeling-hater! They still sound good to me, and they're both still going strong. I anticipate they will easily survive to see 20 years old, most likely 30 or more... I've also got a pair of Roland Cube 60's from around 2005-06. The input jack on one had to be replaced, but otherwise they're both still going strong. 24 bit resolution which is the same as the newer Cubes too. The Yamaha's are a little more robust with all metal jacks and turret board construction, but the Rolands are well designed. I don't have faith in the new Chinese Peavey stuff, or the Fender Mustang series. They do sound good to my ears, but the designs don't seem as well thought out as the Yamaha DGs or the Roland Cubes. Hopefully I'm wrong. I also have a Super Champ X2 which shares some architecture with the Mustangs, but sounds fantastic to my ears. I hope that one lasts a long time!
