I have used many double pedals over the years, I have used sonor, pearl, dw, ironcobra, I was using the sonor pedals until they let me down after 3 years of use, I bought some budget pedals to get me by for a time as I was short of money but these really were rubbish, they were ok for the first 6 months but after that they started to break during sessions more often than not, It was time for me to get another set of pedals and I chose the tama speedcobra after long consideration, I was on a budget and was looking for something that is built to last and would give me a fast pedal for some of the metal I play, I tried the mapex armoury pedals and the pearl pedals before eventually deciding to go with these as they seemed to offer build quality and reliability from a legendary manufacturer that has developed a product through experience, the action of these pedals is smooth and fast, they arrived perfectly setup and ready to use, unlike some pedals you get that arrive with the beaters not in line and need adjustment from the start, all the machined parts seem of high quality, and they seem to use good bearings for a nice fast response, they only down side is you don't get a case but I can hardly complain at this price point, I had a case with my old pedals that I will use but if you don't have one I would recommend getting a case for them if you are going to be gigging, I cannot fault thomann on the price of these they are by far the cheapest outlet I was able to find when you compare thomann £169 to others that started from £360, excellent value from thomann!!, and with free quick and efficient delivery, I cant complain, its deals like that that keep me coming back for more, keep up the great work guys!!
