I kind of lost track of all the Catalinbread SFT versions and want to know the differences or summarized: which one is/was the best? I used to have SFT v1 but sold it and might regret it now. My old SFT didn´t like my active basses, even with powering it with 18 volts, but now i mostly play passive basses in C-standard tuning (stonerrock). Or should i better aim for an SFT alternative? Most important for me is touch sensitivity: as harder you hit the strings, as more dirt comes out.
