I'm currently trying to decide which one of these wahs to buy. My searches here have not turned up any head-to-head reviews/comparisons. They are close enough in price that it is not an issue. I am normally very leary of buying gear that I have not played/heard. Unfortunately, there is no possibility of AB'ing the two anywhere close to this area. I know that the RMC is true bypass, but am not sure about the Earthquake. I also have no idea about customer service on the Earthquake. Mr. Teese obviously enjoys a reputation for untouchable CS. Lastly, a description of the tone of each would be much appreciated. Thanks in advance.
