In this video I compare a 1963 Vox AC30 to a 1966 Vox AC30. They both sound amazing, but they sound very different from each other! The 66 is a combo and the 63 is head+cab where the cab is open back. This 63 has an Albion Output Transformer and this 66 has a Wooden Output Transformer. Both amps have Celestion Alnicos from respective period, T530 in the 63 and T1088 in the 66, both with Pulsonic cones, should differ only in color. The 66 is a Top Boost model and the 63 has been retro fitted with a Top Boost. I’m playing both amps using SG and Telecaster. At the end of the video I go through a bunch of EQ and Volume settings for both amps.
Here you can listen to the 63 through both a Vox cab and a Marshall cab:
