Have a lot of curiosity for that Bluetube...lot of you are talking about this one. Where I can find one of those?Find a used TubeWorks Blue Tube pedal. It's not a tube emulator, but rather a real tube preamp in pedal form. It's a great way to turn a SS rig into a tubescent sounding one.... Having tried the sansamp pedals I have to say that there's no contest... The Bluetube is awesome.
