info on specs

As far as I can tell, this was the top (or near the top) of the non-solid-top G series in the mid-70s. And the sound reflects it - it's a definite step up from the G85 and G100 even though those are good sounding guitars. The guitar is an attractive instrument despite its nicks, dings, stratches. And yes the top does look red. The guitar has the longer scale (658) typical of the Yamahas of the era. The msrp shown is for the G180 not the G180-1.

Fairly typical condition for its age - nicks, dings... some finish cracking and other minor separation at the binding. There's also some light finish cracking at the neck but the neck appears to be well attached and straight. The tuners are lovely and shiny but are a little stiff in operation - they work OK but look better than they work. There's some pick or fingernail scratching on the top. The back has fairly exensive scratching or scuffing, especially in the belt buckle area but the finish is still shiny and some of the lighter scratches could be polished out. The biggest ding/nick is on the top/side and shows in one of the photos. There's also the typical divot in the head. The frets/fretboard show typical light wear but still have plenty of life. None of the above affects the sound that's typical Yamaha - strong bass, ringing trebles, powerful for the price. Has new TUSQ nut and a nearly new hard shell case.

How it sounds
This recording is a little wimpy - I think one of the mics was pooping out. The guitar sounds better, especially with the new nut, than the recording and I was too lazy to record it again.
