I have to say that this is one great pedal, and that Danelectro is a great company.  I had previously purchased their "French Toast" Octave distortion pedal and that one came with a "knobs protector", basically a clear plastic cover that slides down over the 'fins' on the pedal body to prevent the knobs getting trampled.  Well, this one came without the protector.  The instructions said to go to a parts website to order a cover but that was no longer available from the website. One quick email to Danelectro requesting one, and *POOF*  they sent a protector to me at no cost.  That's the kind of service that I appreciate and I will brag on Danelectro all day long.  Now, as for the pedal itself:  Works like a charm, just as good as a $100.00+ pedal from the big- name brands.  Sweet tremolo with a wide swath of depth and frequency.  Everything sounds good, from the "Monkees Theme" to Pink Floyd's "Money".  My next purchase is Danelectro's Cool Cat vibe pedal, and I will post a review for that too.  If it is even close to the Univibe it's worth it, since it is a fraction of the price of the big-names.  Also, keep this in mind:  The prices on Amazon are competitive, and sometimes they slaughter the competition of the "Friendly Musicians" website.  If you've got Amazon Prime, you get it in two days!  Near-instant gratification!!
