Newbie looking for help

Evening all

let me tell you all a little about myself. I've been learning the guitar for about a year and obviously have a very long way to go but i love it. i have a G series takamine electro acoustic and a washburn hb 30 which at my stage of playing are great. i've had a go at at several different types of music from peter,Paul and mary folk music on the acoustic to blues and rockabilly on the washburn. talk about a contrast but as they say varieties the spice of life. for my first amp i have a Roland micro cube which is ok but i would like to learn to play rockabilly/rock and roll so was wondering which amp i should go for for  this type of music. learning wise, i have had lessons and i previously played the banjo for 18 months. i am also working through the fast fingers course that i have just bought. Any help would be grately appreciated.

many thanks
Brewster
