Hi, Mike.  
 
I've got a Vibrasonic, circa 1960 that, if  
I'm not mistaken, uses this vibrato circuit.  
It's the circuit with the tapped treble pots.  
 
This is just my opinion, but...  
I'm not real crazy about the vibrato effect.  
It seems very abrupt to me, almost choppy. Could  
be just this particular amp, but I much prefer  
the blackface type tremolo. One other thing I've  
noticed is that when the intensity is set to max,  
the speaker cone whomps around a lot in sync with  
the vibrato. I wonder if that can be good for the  
speaker.  
 
Part of the whole deal is I've never much cared for the overall voicing of the amp. The vibrato circuit might sound great in a better sounding amp.  
 
Re: your speculation that it might sound like a phaser - mine doesn't. One peculiarity of the  
amp is when you turn the speed control down the effect diminishes dramatically and disappears altogether below a certain setting.  
 
Regards,  
Steve F.
