Sax or Axe ... ??

Just joined ! Folks, I have a question .... I've been listening to Buddy Rich's version of Three Day Sucker on and off for quite a few years . It's written and arranged by Bruce Lofgreen. Originally it appeared on the 1975 LP Big Band Machine, but I discovered it later in the early eighties on an Italian LP called "Giganti del Jazz Vol. 88" here in England. The question is this ; the instrumental solo...It's obviously over-driven through an amplifier, and there's a wah-wah pedal happening . . . and I KNOW this sounds like a really stupid question, BUT; what instrument is it? I'd always assumed it was guitar.... But sections of it really sound like saxophone. Not only that , but the actual notes played seem to sound very much like notes a guitarist is more likely to play in places , then very much like those a wind instrument player might choose. Almost makes me think of Allan Holdsworth in places... Not the overall feel, but his intended blend between guitar and horn sounds. Can any of you help, please? It'd be much appreciated.
