Yes and yes. Buffer is based on the Klon Centaur's which everyone is praising for whatever reason (it's a very basic yet effective opamp buffer). The boost I've made so far is based on the Echoplex preamp. It's not what you'd call a clean or transparent boost though - it adds quite a bit of grit.
Sales are definitely trending up - the last couple months have been pretty good - but I don't think it has anything to do with the video or radio interview I did. The vid will only go on TV if I win the award on the 25th. And the radio interview was only broadcast in Ontario (500k French speakers.)
Interesting phenomenon though over the last week - people have started emailing me asking for a job. Three of them so far.
(I can't really afford staff, unless their salary is subsidized. Looking into that right now.)
