The box exists because the session needed it.
Jonathan Little spent twenty-five years as the staff tech at A&M, Conway, The Village and Cherokee, building one-off boxes to fix what those rooms ran into that night. Little Labs has been selling those boxes since 1988.
Twelve boxes, each one aimed at a single problem
Phase you can hear but cannot flip. A DI that has to go both directions. Bass resonance that lives under the note. Every one of these started as a favour for an engineer who was stuck.

IBP / IBP Junior
The phase control that a polarity button cannot give you.

Little Labs publishes a partial user list of eighteen names and a handful of quotes, buried at the bottom of one product page. They are worth reading first.
The PCP is really amazing, –it does a lot, but what I really dig is it allows me to use my vintage effects on everything. It is my ultimate studio tool.
One man, one bench, a house in the hills
Little Labs is Jonathan Little. He learned electronics in the 1970s in his father's lab at Stanford, took a course at the College for Recording Arts in San Francisco, then went south looking for a recording studio and found nine of them.
Salty Dog. Devonshire. Cherokee. Toto's 1984 world tour. The Village. A&M. Conway, as chief tech. Marcussen Mastering. Chalice. Every product in the catalogue traces back to a problem in one of those rooms.
Sold through dealers, in eighteen shops on four continents
Little Labs does not sell direct. Sweetwater ships anywhere in the United States, Perfect Circuit and Vintage King keep stock, KMR Germany ships almost everywhere outside North America and Australasia.
