If I was there,I'd buy it,but I'm a gear pig.Seems to be in great shape,except for the tear in the grill cloth.I like the variable Bright control.I believe it's a mid - late 70's piece,make a great little practice amp.As to the spkrs.,108 G,I think it means,10" spkr.,8 ohms,for Guitar.Good luck,Mel.
