Welcome, and thanks for giving me a shot

I saw your order go through, you'll get an email when it ships, but I also tend to post updates throughout the month on the build process.
I've heard good things about the Arkham, looks like a neat one. It's honestly a little weird that there are so many B15N based preamps out there but they all seem to be successful, nobody is really stepping on anyone's toes.
On that note I got to try out the new V15 preamp from Tsunami Cables at NAMM, that was absurdly cool. It's a little pricey, but you have an independent 60s voiced B15 pre with a 6SL7 and 70s voiced B15 with a 12AX7, and you can blend the two. Killer sounding preamp. If I could fit a 6SL7 conveniently into a pedal enclosure I would absolutely use that instead of the 12AX7.
