Actually Etch sounds different from Volcano...which I have and love (FabFilter, natch) and its GUI, at least to moi, seems more intuitive. YMMV.
Sometimes when I hear sentiments like Bit's it gives me pause...thank goodness...but then I remember that just like a Les Paul sounds different than a Strat which sounds different from even a Telecaster or an L-5 that different eqs, compressors, phasers, flangers, filters, insert your effect here do the same. YMMV.
