It's quite likely that when Hendrix went to London the first time, he was the first person ever to play a Stratocaster through a Marshall full stack at full volume. Also maybe not until the night of his first big gig there. Townshend had Marshall build 100 watters so he could play louder clean, Clapton had already been cranking it with a Gibson SG which is a characteristic sound all its own, he was in the audience at the gig and was blown away watching Hendrix. Every year from at least 1964 to 1984, more advanced amps were made than ever existed before.
