I don't own one, but I gave one (an F1, I think) a good going over in a shop. It was ok. For £300 it wouldn't have been too bad, but it was £600!
The neck was super-wide - wider than an RG, I think - and had a very flat fretboard indeed. The problems were all at the other end... the pickups were very nondescript - I'd definitely take stock Ibanez Vs over them - and the pickup selector switch clicked and popped when touched.
The trem was even worse; some of the fine tuners felt as if they had grit in the threads, others were really stiff, and one seemed to just be spinning and spinning without doing anything.
Overall it wasn't a patch on my RG570, which was the same price new. With a proper setup and new pickups and a decent rewiring job the Maverick might have been a decent enough player, but I thought the price was double what it was worth. To be fair, though, I only tried the one and it's quite possible that that was just a lemon.
