The Red Witch Pentavocal tremolo is my favorite all analog tremolo. Hands down. Aside from excellent sine and square trems, I mean chewy trem, and there are other pedals that get a similar chewy trem, non better though imo. Aside from the great tone, this trem offers the amazing "bottom" feature, a dedicated knob. The bottom allows you to have full trem throb in the bottom frequencies and no trem in the upper frequencies, just regular guitar. It's very musical to have both things, the clean and the throb, sounding at the same time. Are there any other analog trems that do the "bottom" feature. I have the chrome one, an earlier version, nothings changed except they don't use chrome anymore, the lettering came off.
