1 ThePolecats 6 months ago At GC yesterday I was browsing their used gear and I saw this cool Yamaha guitar amp that’s a triangle and reminds me of a pyramid. I think the surf band from the early ‘60s, the Pyramids used this model amp. LOL. Usually they have tags on their gear but this one was missing it so not sure the price, Year or model. I did some research and they had many variations of this. Some downright big. I think a bass version too. This one is on the smaller side. These are solid state. They have a special speaker. After market speakers won’t fit. Wonder if this sounds great or bad. I want to go back and try it. Any of you seen such a thing?
