Der Nano Small Stone klingt eine Spur anders, im Bassbereich etwas betonter dafür etwas dünner im Frequenzspektrum.
Der ältere Smalls Stone soll etwas breiter und wärmer klingen als der neue . Ich denke aber, dass kann man vernachlässigen.
Ansonsten lies das mal:
The 70s SS has a warm, vague kind of soud to the sweep with the colour set low (great for reggae rythmn playing), is good for clean sounds and Hawkwind kind of sounds in the middle, then passes through a strong fake Leslie before getting very drunken at higher rates. With the colour switch up the pase is much more pronounced, but still warm. The higher reaches of the rate knob are pretty much just warbling noise though.
The Nano SS on low colour has a crisper sound. Not like an MXR, but more sharply focused than the 70s pedal. Not worse, but different. The rate control is better with a more useable range.
Set the colour high and the phase is very noticable - sharper still and the opposite of subtle. Both settings are far better and more organic than any of the digital phasers can manage, though I'd really like the vintage low colour with the Nano's high colour settings.
Switching the colour also changesthe rate slightly - the rate control operates over different ranges depending on the colour setting. Personally I think this is a good idea as the high colour is more suited to long, slow speeds and vice versa. I can see that might be a problem for some though.
Finally, the 70s pedal cut the volume lots when engaged. The Nano still has a slight perceived volume drop, but nothing like as much (and could be the result of switching it on when the notes I'm playing are not in the focus of the sweep). I found the 70s volume drop a problem, but not with the Nano.
