Yeah, I have that interview with Jack Bruce on one of his DVDs, where he said he did not care for the short scale EB-3 and wanted a wider range of tones...! Uhh...all the while he is holding the short scale EB( original '50's version not the '69 also short scal and mudbucker).
Yes , I do too love my '69 EB-0 and these days as i get on in years is sooo comfortable to play and even don't mind the mudbucker.. I actually have entertained the idea of putting in the 'fake' TB+ that is found on the SG basses for some interesting tone balance...but never pressed the button yet on that.
