anyone ever used a grooves tube gt55 condenser? please tell me how it is.

I used to have one- good for recording clean electric guitar and some male vocal apps- the mic sound is a little thin so i didn't like it much with female vocals. I also have the 319- actually 2 of them and they sound different from each other! The 319 is definitely darker and I do prefer it over the gt55- the Gt 55 I believe is the same as the groove tubes am11, which used to be the model # when alesis owned groove tubes. you can pick up an am11 on e bay for around ahundred bucs, while I think the gt55 is around 3C
