1 archtopisking 10 months ago I did a little comparison of my amps . All of the amps sound good / great / better than me , and my favorite is the AC 30 with the marshall cab . But is there something going on with the Vox 2 x12 cab ? - It has a 63 celestion blue (15w 8ohm) and a new celestion greenback Gh12 (30w 8ohm). It lacks the power and sounds thin compared to the others . The Tremolux is also 30w and is a lot louder with its cab ,than the AC 30 with the Vox cab. (not so when I use the marshall cab) My meter shows 15.8 ohms and thats what it should be. Any thoughts ?
