when i tried it out, i did have my amp cranked to normal playing volumes. for some reason, it just didn't have any useful sound in my rig.I think the phrase you should use is play it at gig levels. There are lots of dirt pedals that sound like crap in your bedroom with the volume below 9 o clock. Open it up and get it loud and the Voyager shines.
sent it back and i'll be sticking with my Timmy. i might try a KOT, and if it works, it could replace my Rook and Leonard OD (considering the latter gets fixed).
