Hi Dennis,
where's he staying?
If he's near Ipswich I have to vote for my local, the Guitar Shop -
http://www.theguitarshop.co.uk/ - great shop, where you're welcome to select from the stock and disappear into the amp room for as long as you like.
In Colchester there's Trevor Durrant Guitars -
http://www.tdguitars.com/ - which also has a good stock. Ive not had a good twiddle with their stock, but then Ive never asked. TD Guitars is in an industrial estate, right next to a large drum shop and a large keyboards shop.
