This little box made traveling so much lighter. The output is high enough to put straight into a mixer and is so close to a real guitar cabinet, it replaced my guitar amp. Good for small gigs and great for band practice, given you have your own PA. Also, the quality for the price is amazing!
There are some cons though. The headphone output is very noisy for low impedance headphones, it hisses and is way too loud for personal monitoring. If the headphone out was designed for low impedance, this box could work as a in-ear monitor amp on stage, but as it is made for high impedance and most in-ears are low impedance, it won't do. So, bummer!
Second thing is, I really think this should have an effects loop before cabinet simulation to really be versatile enough for a full gigging rig. It is good as it is, but leaves me wanting to use my own delay and reverb, not the mixer's.
