I just switched to bass after years of playing guitar. I've selected a bass, but need help selecting an appropriate gigging amp. I've narrowed the choice down to a Fender 250/115, a Fender 250/210 or an Ashdown 410 MAG (300 W). I can get a Fender from a local dealer but will have to mail order the Ashdown. I mainly play Police, Beatles, Stones, but also Rush, a little Alice Cooper and some Southern Rock. Thanks in advance for the advice.
