I wish I read a bit more on it before buying it. Without boost engaged pedal is rather wimpy - especially on Plexi mode. And Boost pushes the volume up way way too far - even with both trimpots CCW. It basically becomes a different pedal with Boost engaged. That is not at all what I was hoping for - somehow I thought I could use Boost to get higher gain at the same (or slightly higher) volume level. That is rather disappointing - I had higher hopes for Bogner product. And NONE of the YT reviews ever mention the problem with Boost - that more or (as some people on TGP mentioned) is design FLAW. Not acceptable in $300 pedal. Not sure if I should bother to try Red or go back to Wamplers.
