I am there if there is a comparison. Just keep me in the loop. I normally don't go to SPAH but I will if there is a venue for the amps. Normally SPAH is not noise friendly. Mike did Rupert tell you there was a comparison of the WEZO 45 and the HG50 at Buckeye? Thanks and looking forward to SPAH, Brian http://www.harpgear.com
