(con't from below) From the Output Jack On Your Guitar to Your Cabs..try to find rack units with dedicated fx loops and dynamic range < -90 db; preferably < -100 db. Also, Don't skimp on cabling..one cheap cab cable can make you sound like trash...kinda like golf...a custom set of clubs won't ha...
WOW...the Helicon is not the show here....great voicing and guitarmanship (if that's a word)...Chet himself would be proud..
