Spacealf, Rick guitars do have a very distinct tone to them; a sound all heir own. Love the 12 string guitar jangle you get from a Rick.
The bass has a distinct sound as well, but different from what most think. Most people think that it has a very trebly sound to it based on how Chris Squire went out of his way to get that trebly tone. In actuality, it has a distinctive growl that comes from the bridge pick up and is perfect for Rock; especially pronounced with round wound strings. The Rick bass has a very solid punchy bottom end as well and can get a variety of tones based on your touch and pickup selection. I have La Bella Flats on it right now and I am definitely getting that McCartney thumpy tone that you associate with his playing. The bass is also known for its outstanding sustain. The tone I am getting right now sounds exactly like stuff off the Abby Road album, think Come Together or Something as an example.
