SUUNN 412SR - This rarest of the rare 1969 vertical tower cabs, the first ever IR capture of this cab.  Loaded with four 12" acoustic suspension transducers in an infinite baffle enclosure for extended high-level bass response without breaking up or bottoming out. This cab mic'd dead center on the cap is unlike anything I've ever heard. Dare I say, I prefer it to a V30 in many contexts - a true secret weapon. 

This is a single cab from OTTO CABS Vol I,
which is my personal collection of some of my favorite cabs, meticulously & exhaustively captured to give a guitar tone ultimate power, depth, weight & clarity.  The work was not done until I could sit in front of my studio monitors and get an unparalleled sound / vibe experience as I do with my cabs in the room pushed by electrified iron & glass.  Do not expect these to sound like other IR's.  Like the Eleven Eleven, I wanted to feel the air move - I grew tired of the sound of a mic'd cab sitting in the other room.  So, after 6 months of relentless a/b testing, shootouts among 25+ mics, 12 different power amps, and landing on a Neve signal path ... borderline obsession... produced an unbridled heavy.  A true cab experience coming out of your DAW.  With each cab you get 17 mic selections and 5 "sweet spot" usable and varying positions per mic, all perfectly phase aligned so you can blend and mix in any dual IR loader. 

17 mics, 5 positions per mic - exhaustive and yet easy to navigate and find a great tone right away.

Limitless Phase coherency - Every position and mic was phase aligned to perfection for blending with each other at any position, blending with other minimum phase cab IR's. Mix, match & stack for towers of tone without getting messy.

InteRvaled IR's ™ - I refused to stop with just accurate, or heavy - IR's must have clarity, articulation and sound pristine when playing power chords without congestion. Impact on chugs and separation when playing intervals is near top of the list of requirements when choosing a tone to play through or print to my session. How is this achieved?  Fine tuning every part of the process and playing/testing by ear, then hand selecting each.

Big Iron Transformed ™ - Power amps that imbue just the right amount of push, texture and harmonics are what make Otto Cabs "secret sauce". Testing thoroughly 12 different power amps, I landed on the one that has "it".  I'll never tell which.

Analog Mojo signal path - You've heard it a million times, but there's a reason for it: analog gear just has that warmth, life and something extra that makes audio feel organic - so I landed on running all mics through a Neve mic pre into a Neve channel strip, EQ and console, finely tuned and adjusted.

In finality, most of all, to bear the name Otto, it must grip you and feel great to play; absolutely crush or it doesn't make the cut.  Every IR capture was tested and played through to ensure it hits you with a wave of aural violence coming out of your studio monitors.
