Ease of Use: 

Powerful amp sims that are enhanced by the use of a 12AX7 tube used to get tube distortion and warmth.  Also has option to use digital effects including distortion and overdrive.

100 user presets and 140 factory presets equals 240 presets in total, some which were created by some very well known artists i.e. Steve Vai, Steve Stevens, George Lynch, Dweezil Zappa, Warren Dimartini among others.

There are still many sights that are available where people are willing to share their created sounds.  I have picked up many cool sounds that have become part of my repertoire.

So many presets available that you may not want to tweak your set-up.  Or you have a great starting place to start.


Programming is not overly intuitive so you may not start from scratch to get your sound.  Manual takes a few reads to get the hang of what they are talking about.  

May need some previous experience programming multi-effects units and differnt effects and how they colour your sound
