I use it everyday and plan a new version! enjoy! I plan a new version with a lowpass and highpass. Furthermore, it should be possible to offer more gain. This could be done by ensuring there was a careful algorithm regarding resonance. So, ultimately, that the resonance would become thin and have less effect when treble is maxed, and in turn that resonance would be more pervasive when using the bass in a negative fashion so as to act as a high pass. Such an advancement could be a real timesaver.
