Well I kind of have a trio of them...
Cog 66 mini - it's my always on with touch of clean blend, bass on full, Treble on normal and gain on half... it's actually not got much gain but almost a preamp for big bass and low mid tones.
Damnation audio mbd1 - on softer setting with gain it can do overdrive, higher gain gets a crunchy distortion which is what I use. Clean blend and the depth knob will give you low end for days or tighten it up to be not so boomy
Aftershock - I tend to use this more for the muff / distortion type engines but do quite like the stock tube setting as a nice OD - with the blend and massive amount of eq options in the neuro app you could dial low end back into any engine pretty much. Or as one user even did as a template- filtered the engine and eq so that you have clean coming through with only a hint of distortion on the very high treble, almost a shimmer to a very clean tone. If you have time to dabble I think possibilities are endless.
Hey, someone else that has had the same experience as me with the Cog Knightfall! I had one, and found it to be a really really low gain pedal...like you say, almost more like a preamp or tonal enhancer. I sold it because I was actually hoping for a gainy pedal, as I already have a bunch of tonal enhancers. Here I thought I was the only one who felt that way...nice to see I'm not alone.
