Well I guess I should probably mention first that I have zero experience with tremolo pedals. Never owned one but have always liked the sound of them in the music I have heard them in. Thinking about picking one up but first..... So I shopped around today and found that there is such a wide price range for these. Some of the boutique ones appear to be really simple with limited features so I guess your not really paying for extra features. Other than the fact that they are obviously built a little bit better and they offer actual customer service, what makes these so much more expensive than the rest? Can a random handful of different tremolo pedals really sound that different? Is it the sound then or what? Again I have no personal experience with these but it seems like such a simple function it needs to perform.
