Re: John Bonham
Mr. Bonham was not addict to double bass drum, in fact he only played it once but the rest of the Zeps nerver liked it. As far as twin pedal usage, at that time, era is hard to believe.
Out of the subject: not even Ian Paice used twin pedal at that time. He only played double bass drum for the song "Fireball".
