Here's where I need to backup an give a little history, about 6 months ago, I bought a used mustang 2, I was getting tired of my Vox AD30VT (great for cleans not for dirty). So I picked up the FM-II. Wow the cleans are better than the Vox, Plus the distortion was just what I was looking for, result - the Vox sold on craigslist 3-days later, I will never regret it. After playing for a while I decided to upgrade to the FM-IV to have the stereo sound, Love IT! Now I have 2 mustangs. II - for the bedroom, the IV - for the Jam room! The Mustang is great for any style of music, at any sound level. It reacts like a tube amp in regard to pick attack. And the sound too, Is much better than the Line 6 crap! (sorry line6 owners... It's true).
Overall Impression — 10
Overall this will be my only main amp for the foreseeable future. I'm extremely thrilled with it.
Reliability & Durability — 7
Basic construction, Not high end at all. Tolex covered particle board, seems sturdy enough. Has a good strong handle. Would survive a short fall, wouldn't test it though! Will last years if properly cared for. As for the aux in & headphone inputs, I have my doubt as they seem a bit fragile.

Mfg'd in 2011 by Fender China. This amp has more sounds than you can shake a stick at! Has a great Satriani sound all the way to the cleanest of blues. Has 100 presets and these are all pretty good, Sounds like Fender hired guys that actually know what a good preset sounds like. Plug it in, Turn it on, the 1st preset is called "Liquid". It's like sliding down a water slide coated in oil! Man does it sound sweet. The headphone jack is great for late night quiet practice. The fuse software is fun to tweak amp presets. Or logon to the the ever growing online fuse community an download their presets.
