Fender Mustang IV V.2
I have been using my Mustang IV V.2 for over two years, and feel that I can now provide an accurate review. I play in a cover band, and needed the versatility to be able to immediately change from a Marshall type crunch to a crystal clear glassy Fender sound, or the soft bite of a British VOX tone. This amp replaced a 2x12 Marshall Combo that I previously used.
The sounds in the Mustang are superb and are difficult to distinguish in sound, and response behavior from tube amps that I have had over the years. As many other reviewers had commented, some of the initial settings on the stock sounds might be set a bit too high for some tastes, but the intuitive controls make this ridiculously easy to correct.
The Fender Fuse software is brilliant in design and layout and it is very easy to use to update the amp's firmware or to conduct deep editing of any of the; amps, effects, speaker configuration, and signal chain preferences.
As far as volume goes, I have never played a gig where the amp Master Volume was needed above "5", and I have played everything from small clubs, large casinos, to an NFL Stadium pre-game crowd. It has plenty of volume and power to spare, and I am very pleased with the sound of the stock Celestion speakers. Of course it also sounds great at bedroom volumes or directly through the headphone out.
As a regular gigging musician, I truly appreciate the reasonable physical weight of the Mustang IV.
The on-board effects are terrific and the sound quality (in my opinion) is commensurate with any stomp boxes out there. Having so many usable effects on board truly makes set up at a gig a breeze. Further, I have grown to exclusively use the XLR line-out connections in lieu of miking the amp at gigs. It gives the sound tech an attenuated signal that is much easier to control and mix than the highs/lows that they would get from a microphone.
On stage I use the 4-button foot controller, with the 2-button controller, and the EXP-01 expression pedal. The ability to have these three items work together provides a very logical means to control the numerous features of this amp. My only criticism is that I find that the control buttons on the 4-button controller are a little too close to one another. If the pedal was 3"-5" wider it would minimize the likelihood that you would unintentionally press the wrong button while on an active stage (I would know...I've done it).
Whether you need the sound of; AC/DC, Earth Wind & Fire, Stray Cats, George Benson, Metallica, DNCE...or any others.....t's all right there at a moment's notice!
Combine this with; the price point of the Mustang IV, the reliability of Solid State digital technology, and the 5 year warranty, and the service and support from Sweetwater and the inherent value of the Fender brand, I found that you truly have a "Swiss-Army Knife" of amps at an amazing price value.
