for reviews,but take 'em with a slight pinch of salt. The best thing is to trawl round you local music shops and play every one of the B_a_S*ards you can find till you find one you like. Ask the guitar shops to give you an amp like you've got at home, as its disapointing to find that it sounds great in a 100w marshall and crappy through a small practice amp.
Good luck.
Accuracy,you say? hmm interesting concept..
