This is a Gibson Memphis Custom Shop ES-137 Premier Prototype Semi-Hollow guitar in a unique antique gold finish. 
The Gibson ES-137 was launched in 2002 as a new model that was similar to the ES-135 but features a mahogany center block to help with feedback and allows for use of a stop tailpiece. 

As a one off prototype model this guitar lacks the typical interior label. The guitar has the serial number stamped on the headstock and include the original case, custom shop certificate of authenticity and the Gibson hang tag.
