Everything in my chain is currently TB except for the last two pedals; a Keeley modded TR2 and a Maxon AD900. Analogman offers a TB mod on the AD900 that I think I am going to do because the switch in my unit appears to be wearing out. It doesn't even click when it is switched on or off. I really like the TR2 and I don't want to trade it for a different TB trem because I have preferred it to a couple of TB trems I have tried. So, I was thinking of having it rehoused and TB'd by someone like Swankbox. What I am trying to decide is if having the buffer of the TR2 at the end of the chain may actually be helping my tone by giving a little signal boost to the amp that I may be losing after going through all of my other pedals and cables. I could hook up one of my spare micro loopers and experiment, but it still wouldn't really be the same as a/b'ing the TR2 TB or not. What are some opinions out there? I know, I know, I like my tone, so don't fix what is working. But, as I said I think I need a new switch on the AD900 anyway and would dig a rehouse of the TR2 also.
