The ACME is lush! I have one and I love the low tuning. If importing another from the US was not so painfully expensive, I would have 2. The low end is pretty addictive. I have experienced the less efficient nature of the cab and flogged amps which were not happy to drive it, but I have no DB amplification GAS now (apart from the desire for a 2nd one). A low tuning option on this build might appeal to some people who were happy about the efficiency trade off.
