I just got a 1966 Fender Vibro Champ in a trade. I LOVE the tone. I'm not too worried about the vibrato as I'll be using it more for Jimmy Page type tones, but the vibrato seems to be VERY subtle...to the point where you actually have to listen pretty closely to hear it. Is this the way it should sound? I'm used to my mid-70's Twin Reverb which could make you seasick with its vibrato. Thoughts from any Vibro Champ owners would be appreciated.
