I’ll admit to having a little bit of a brain-jam over the fact that Fender offers a very traditional, longstanding guitar model called the Mustang, as well as a very modern digital modelling amp of the same name. But the Mustang guitar has its roots in Fender’s early student guitars, and the amp line has a bit of the same ‘make it easy for everyone’ spirit, so in another way it totally makes sense.

The Mustang amp line is designed to take new firmware updates, which can be as simple as changing the taper of the control knobs in response to player feedback, right on up to entire new amp models; an update pushed out in September adds a variety of new amps inspired by models by brands like Mesa Boogie and Friedman, as well as a handy tube preamp model for recording.
