Fender "amp guy" Shane Nicholas gives Gearwire listeners the low-down on the development of Fender's line of GDEC (Guitar Digital Entertainment Center) modeling amplifiers. He also delves into the differences between the GDEC and Fender's first line of "modeling" amps, the Cyber-Twin series, and talks about how Fender tackled some of the thornier problems of amp modeling. Interesting stuff.
