I use this for my acoustic guitar and nylon string classical guitar. It sounds great with both these guitars. The preamp (Treble, Mid & bass) works like breeze. If you slightly reduce Mid for acoustic guitar, it sounds really great. On board 'Reverb' effect is of high quality, it works so nice while playing lead especially with classical guitar. I am surprised that Mic works great in this little amplifier. I use Shure SM58 in one channel and acoustic guitar is another channel. The ability to tweak the EQ and Reveb separately is for these two channel are really useful feature. I use it for live gig where i use Line out (XLR out) from this amp to the main mixer. If you use XLR to XLR the gain is too much and it clips in mixer. Hence i use XLR to TS cable (XLR out from Fender amp to TS input in mixer, then it works like a charm) I am very much satisfied with the quality of sound and line out i get out of this little amplifier. It is slightly heavy though it looks small; considering the quality of sound i don't complain about the weight.
