This Special Edition improves upon the original by offering lower distortion, more stability, an improved damping factor and a better dynamic range.  It does, however, maintain the classic look of the GFA-555.  The circuitry has been upgraded, and it has a power rating of 200 Watts into 8 Ohms or 300 Watts into 4 Ohms.  It will sell for a suggested price of $1,299.
