As heard on : "Don't Stare Directly At It!" by Sunny Davis & The Gas Giants
Reason to buy : Because you've secretly always wondered what would happen if you could somehow blend the sound of the optical trem in your dusty old valve combo with the usability of an iphone ( other smart phones are available ). No forget about it, its too wild an idea. A robo-trem for the 21st century, with all the digital control you'd ever need like selectable waveforms and ramping features, melded with good old fashioned analogue tone? It can't be done. No one is that....Oh wait.
Reason not to buy : You fear change.
Fun fact : Tremolo as an effect, is the third easiest way to get a hippy to fall asleep.
