It's interesting looking back and seeing how my rig has changed over the past 10 years.
Here's my 2004 rig I recorded my first solo album with, pretty simple rack and way too much speaker cab:
Over the next couple of years I really messed with the rack and created what I consider the ultimate Rocktron Chameleon rig. This was the rig I used live for about 3 or 4 years and recorded my old band's first album with:
Upgraded to a Triaxis in 2008 and this was what I used on my old band's second album, this was an awesome sounding rig and I still stand by that preset showing on the Triaxis, it's a KILLER rhythm sound:
In 2010 I tried my hand at the Axe FX, and while I loved this rig, it was just too awesome that I messed with it too much and didn't write a lot of music:
2011 I was going through a time of transition in my life, and it showed in my stripped down guitar rig. I had gone months without a guitar rig and this was me just beginning to build it back:
I picked up my Triple Rec back in 2012 and I love it. I wound up sticking with the HD500 and kept it in my rig, it's wildly versatile for how inexpensive it is. Here's my setup as I have it today. I am totally happy with it, running the 4-cable method with a Pedalsnake between the HD500 and the head, which allows me to run effects before, after, and if I want I can bypass the pre of the Mesa and run direct into the power amp. Awesome setup and I'm working on putting together a band again to play live. I do miss playing live, for sure.
Those are some awesome rigs man! My Zilla Fatboy, like your Mesa 412, is the only consistent part of my rig since I got serious about playing. It attests to the power of a good cab.
