"Vox amplug 2 AC30. Wow!"
Can't quite believe the sound quality of this little headphone amp, it's just like the real thing. The tones I'm getting from my Strat are sublime, I can't put it down now I can play away in the living room. I have Boss ME80 that has a AC30 pre-amp but this is much better, it must be the analogue circuitry, no digital mimicry. The effects are a nice touch even if a little bit fiddly to operate but you soon get used to it.
One thing to remember though, is that this is an amplifier so the quality of the output is made relevant by the quality of the headphones you use. You don't need a expensive set, just a half decent set of over ear phones work great.
