if you wanna hear how Rickenbacker guitars sound like at their best, run one through a Vox amp, or you can listen to the earlier Beatles records.
Rickenbacker 325 - Jangly, glassy, twangy sound on the few records up to Rubber Soul, when Lennon changed to a Epiphone Casino.
Rickenbacker 360/12 - Bright, piano-like twang. This guitar has stereo outputs. A radio station bought it for George Harrison. although this guitar is famous for its opening chord on A Hard Day's Night, it was first used on You Can't Do That.
i loved the beatles and their guitars =P
