I would suggest a good effects setup. Wether you get individual pedals (more expensive in my opinion) or a multi effects unit is up to you. But is sounds like you are looking for some delay and maybe Chorus. One multi effects unit that I have been real impressed with for the price is the New Digitech RP Pedals. There is the 150 the 250 and the 350. You can check them out a www.digitech.com the 150 goes for about $100.00 and the 350 is around $200.00 to $225.00. My friend has the 350 and it produces some really good sounds. Blues, Rock, Metal. And Several Signature sounds like Metallica, Stevie Ray Vaughn, Etc. Anyway hope this helps. Also you might want to try going to a good music store and have them play some of these different units for you so you can hear for yourself.
