Rickenbackers can do clanky. But solo the neck pickup and roll off the treble and you have a great thick thumpy tone. They are far more versatile than people give them credit for. Properly EQ'd you can get nice grindy rock tones, clanky Chris Squire tones, and rounded Jazz tones.
The playablity is a bit Marmite though. I love mine, but the necks do take some adjusting to if you're used to a Fender.
