They buy and sell mostly used guitars and amps. They also sell all the accessories that you will need to accompany your guitar purchase; strings, straps, amp cords, picks, tuners etc.. these items are all new.
You can find some good deals on used acoustic and electric guitars. If you are selling, be warned you will only be offered about 1/3 or even less of the retail price of your guitar or amp.
These are no-nonsense guys that are not "chatty cathys" buy any means, do you know the type I mean? Buy or sell and split!
