Recent addition of a quality tube amp has opened a whole new world of "pedaldom" to me. Just acquired a 3 knob Bearfoot Honey Beest and it is phenomenal. I am running Honey Bee > Honey Beest > Tim and I've got to tell you, I didn't know guitar tone could be this sweet. As a side note, I've got a Timmy in front of dirt and a Tim behind. Tim behind sounds multiples better!! Question--How much better could the Beest sound by having a fourth knob? Are there 3 knob owners who switched to 4 knobs Beests and feel they didn't gain much? My understanding is the 3 knob's set pregain is at about 3:00 on the 4 knob.
