I'm pretty confident I will receive the amp as promised. In my opinion, for whatever that's worth Cameron is experiencing what any successful small business experiences: growing pains. I work for a small business that distributes and installs hospital medical equipment. When business is good and we don't have enough technicians to install the product, our lead times go out until we are able to catch up with the demand. Customers get pissed, tempers flare but in the end everyone wins. From what I've read the only thing Cameron is guilty of is poor communication. If they can fix that and hire some qualified people to build the amps they will keep growing.
If the amp sounds anything like the clips and is as versitile as folks are saying, then this is like being in on the ground floor of hot IPO or something. 4 months is nothing to wait for an amp of this caliber. I'll hang in as long as it takes.
The upside is I end up with a kick ass amp...I'll take a shot on the amp.
