A while back, a few of us reported a terrible sound thru the UR824 when using clean guitar. The only way I’ve found for a usable clean guitar with the UR824 is with a REDDI (Tube) Di box, by A Designs. Others purchased other DI boxes with no success. The REDDI costs nearly as much as the UR824, but it works beautifully. Just a heads up to those who haven’t had success yet.
