Essential
There are other options for 1176/LA-2A chain, but this:
Sounds great - very difficult to lay master vocals when you’re fighting to get a sound. This takes that fight away, so you can concentrate everything on material and performance.
Cost effective against alternatives.
Road Tough.
Big knobs, switches and VUs - no digital futzing, firmware upgrades, passwords or spinny beach balls. Just electricity and pure SOUND.
Preferred Settings + Usage:
Lots of gainstaging options between circuits. Hit the 76 5ms attack fastest release, grabbing peaks -3 to -5db compression, 2A smoothing around -2db
