Hi All, I've been trying to learn about the various different kinds of tremolo as of late. I'm particularly interested in Brownface-style Bias Tremolo pedals. Regarding Brownface Trem, I understand that there are two types - larger amps (larger than the Deluxe) had harmonic trem while smaller amps (Deluxe, Princeton, etc.) had the bias trem that I'm interested in. I understand that the Origin Effects RevivalTREM is new out and has made a big splash. I get the impression many feel it's the most accurate reproduction of bias trem in pedal form. If I understand correctly, one of its competitive advantages is that you can 'play through' the trem (ex. if you play/pick hard, the trem is not evident but slowly begins to become evident as what you were playing fades out). So... 1. What other bias trem pedals are out there? 2. Do any of them allow you to 'play through' the tremolo (ex. does the trem respond to your dynamics?)? Thanks!
