The MORE and The Detective are totally different. If you want a 2-channel preamp, one clean and one dirty channel, then you want The Detective. The MORE is just, what I would call, a super-saturator - it adds lots of tube juice to your sound. The MORE itself isn't a preamp; in my use cases I have found it most useful in the FX loop of a solid state amp, as a boost into another pedal, or as a boost post-preamp. If you just want a boost, I would suggest either the MORE or the Finally (or Space Heater if you want to build one yourself or can find a used one). If you want a full preamp, then go Detective.
You can also just get the Elementary and decide which way you want to go from there, too. I know I'm not being super helpful here, but I would just point out that the MORE isn't a preamp pedal, it's just a tube saturator/boost.
Hey thanks for the reply. I'm aware of the differences but I'm not sure it'll make much of a difference in how I generally use whichever pedal I pick up. I'll explain my use case.
I am playing a Jazz Bass into a RNDI (occasionally with compression). I love the sound of my JB clean, especially with the reinforcement (not sure what other word to use) that the RNDI gives the signal. It's full and has some nice harmonic quality to it.
Id like to add another subtle source of harmonics as an always on (or nearly so) pedal. The More seems perfect for this. I wouldn't use it as a boost necessarily, because it'll almost always just be on.
My other alternative is to go with The Detective. Listening to demos on YouTube of both circuits, I really like the sound of Elementary with little to no drive. I imagine that it sounds different than the more does, but if set subtlety I could achieve a similar addition of subtle warmth to my signal. The benefit of going with The Detective is that in addition to the 'clean' setting I would use with the Elementary, I can swap over to a much more driven and flexible signal from Dr Watson when I want to.
Basically I would use More or Elementary as a basic/subtle signal fattener, but if I get The Detective I have more flexibility. Without hearing More in a demo, it's hard to know how similar or different it sounds to Elementary dialed subtlety.
Hope that makes sense.
