does anyone briefly explain me the differences between...?? - Celestion G12-65 - Celestion G12M-65 (Creamback) - Celestion G12H-75 i visited Celestion website. but cannot imagine what are the characteristics with their explanations and the frequency response graphs. i have a two rock sensor 22 head and a cap with 2*Celestion G12-65. i cannot get the tone like my reference video: https://www.youtube.com/watch?v=hr90jeheFDQ in the reference video, they used G12M-65.
