I'm thinking of buying Millennia Media TD-1 for various applications. But, one feature I'm particularly interested in is the "speaker soak" funtion (which allows the signal directly from the guitar amplifier to go into the board). I'd love to hear some experiences using this feature. Could you kindly let me know pros and cons? Also, how the speaker soak compares to the function of dedicated speaker simulators such as Palmer or Motherload? Thanks.
