I'm looking to buy these two pedals but they are hard to come by used. So before I spend $500 for both of them new I wanted to see what you guys had to say about them. Empress Tremolo I'm pretty set on this tremolo as it has the tap tempo, rhythm, & ramping options as well as being true-bypass. However, does it handle a clean AND distorted sound well? And how choppy can the square wave get? This one will be replacing my Dunlop TS-1 Tremolo which has a great choppy square wave. Dr.Scientist Reverberator This will be replacing my amps limited reverb. How well does it handle the clean & distorted sounds? Frazz Dazzler A cool/different fuzz I'de like to get my hands on but can't seem to find it for sale anywhere. *Anything you guys can tell me about these pedals (or if you have suggestions for other similar ones)...would be greatly appreciated. Thanks.
