Here's the NUX Melvin Davis Preamp. Total opposite end of the spectrum in terms of price. Noble is over $1K, the NUX is $179.

Again, played with a Sadowsky NYC JJ with VTC about 50%.
First segment is just the Sadowsky without the NUX engaged.
Second segment is NUX engaged with EQ at noon.
Next several segments are me playing with the EQ controls: increasing bass, increasing mids, reducing treble, adding cab sim, adding different levels of OD.... etc.
Final segment is Sadowsky without NUX engaged.
There's a whole lot more to play around with including other cab sims, more sweeps of the parametric mid control, more blending of OD and clean signal... but just to help give an idea of the thing, here you go.
Please listen to these clips with quality headphones to hear the nuances.
