I have been using OC45's lately, as the supplier I get them from has black glass CV7003/OC44's only from hfe of 130 and above, but has OC45's in the 70-100 range. I am not sure which brand they are. All 3 builds I used them on had the collector voltage at -7V without needing to bias, and they all sound great, unlike the one I build where I used a long-metal-can AC128, that one sounded really harsh and unpleasant.
I was wondering about the importance of Transition frequency. I am assuming it doesn't matter for guitar effects as the frequency lies in the MHz range, way above the KHz range of the guitar. This is the only major difference I could find between an OC44 (8MHz) and an OC45 (4MHz).
