I returned a Helix Rack and purchased the Kemper Rack. The Helix did not provide me with useable tones. I worked with it for three weeks and I kept returning to my 11R. My new Kemper arrived today and within an hour, I dialed in some great tones which surpassed my 11R. The members over at TGP beat me up for my comments about the Helix being less than expected but, I guess this is expected from TGP - that forum needs to learn civility. Anyway, I am a happy Kemper owner looking forward to being a member on this forum.
love from the Motor City!
