This is the first time I recall seeing any ads in a magazine for RIC, the Thundering Tone ad is in the new issue of (UK) Bass Guitar Magazine! You know, this ad:
Interesting bass, looks like a 4003S with deluxe inlays, but the body contours are even more rounded off.
The ad is from Rosetti's, with their contact info in the lower right corner.
That ad has been in Bass Player magazine several times. Cool ad. I collect RIC ads. A rare one is for the acoustics. I have only seen it one time in Acoustic Guitar magazine in 1999. I removed and framed it. I have about 15 or so RIC ads framed. Pretty fun stuff.
I'm sorry, it wasn't from Bass Player...it was from "Guitar World's Bass Guitar" magazine. I have an extra one of these ad's if you're interested. No charge, I could just mail it to you. Let me know.
