I saw Joni Mitchell's "Miles of Aisles concert or at least the performance from the tour the the record was spawned front. The Band: Tom Scott — woodwind instruments, harmonica Robben Ford — electric guitar Larry Nash — piano Max Bennett — bass John Guerin — drums, percussion they were great . Ms Mitchell uses lots and lots of tuning as you may understand She has very discriminating taste for excellent sounding instruments She has played Martin D-45, a Martin D-28, George Benson model guitars. She has an ear for fine instruments. When I read that Ms Mitchell was going to use a Variax I was really surprised, a little in disbelief. Having heard her music live I knew that she sounded great we playing unaccompanied. A VARIAX?. so I tried one on for size, having owned and sold an excellent old national steel body guitar , I just had to hear how it sounded, and hot dog it sounded great and so did the dobro. Now this part is for all the down tuned guys , the varax using the software can be tune to different tuning and stored with the patches saved to the guitar. example tune the guitar to the normal guitar tuning. build an instrument , choose the pickups etc etc and not have to ever retune the guitar , one tuning in the real world and as many tunings as the instrument can hold , plus everything can be saved and backed up. Chose the down tuned " C " and your string tension is the same as usual, open "G" same/same open D same/same no retuning between song of even during songs , just switch the program and you're immediately retuned. so the variax in all it's different price ranges ( there were 3 at the time that I bought mine. economy, traveler and first class, all of which had the same electronics, the variax adrian Belew has on his custom Parker guitars . one size fits all.
