...and I bought them on the spot! I found an ad in CL for a quad of matched 1979 G12-65s, like new. They have the Marshall sticker on them. Original solder joints and wire. I had just finished band practice running a '74 Marshall SL through my 2x12 V30 cab. My ears were ragged. I stopped by the guys house and plugged the 100w beast in. The tone just buried my V30s. I use an attenuator with the V30s, and half the reason is to compress the treble spikes. The 65s were nice and smooth, unattenuated, all the way up. Never heard my amp sound so good. They were mounted in a rugged 3/4 ply Ross slant cab. I may just put casters on it and call it good. All this for $300!
