I've just got myself a PJ Big Head and so far, have to say it has impressed.
I've done a bit of recording through it, on to my computer, which worked well and sounded great.
Have practiced some tunes with headphones plugged and not suffered the wrath of mrs mac.
Tried my I Pod through it and then into my hi-fi.
So, all great so far, plus it seems very well built and although tiny, feels reassuringly robust.
