What's an Orange Drop mod?

The 1176 Rev D with Orange Drop mod has a hybrid tone of a Rev D blackface and a Rev A blue stipe. It has the general tone of a Rev D with some of the bite and grit of a Rev A... but with the lower noise of the Rev D. Its almost the best of both types. I personally like it when you would want to use a Rev A on a snare or vocal that is louder in the mix, but don't want the overall noise the Rev A adds when the snare or vocal is at a higher level in the mix.

This revision covers the REV B thru E units. Most current reissues are based on this revision. Revisions C-E had a black front panel while the Rev B retained the silver and blue stripe panel. Changes were made to the stage and line amps so a bipolar transistor was used as the first active component. Low noise, or “LN” circuitry, was added to this and all future revisions. Like the Revision A, the input uses an O-12 transformer and the signal is attenuated at the input with a 600Ω T-pad. The output is class A, utilizing a 5002 output transformer. This is widely considered to be the most classic FET compressor sound.
