Mark Knopfler

In the first Dire Straits album, he uses a Hot Cake as booster and a Dan Armstrong Orange Squeezer as compressor. The 80s version has a Mid Lift switch (the later versions change for Presence potenciometer, but has basically the same effect).

Between 1978 and 1979, on the first tours with the original Dire Straits setup, Mark Knopfler used only two effect devices on stage: the Morley volume pedal, and the green MXR Analog Delay. Mark used the MXR not so much for the long repetetive delays like on the intro of Down to the waterline (this was a Space Echo from the mixing desk) but rather for short slap back echoes that made his guitar sound thicker and fatter.

The old MXR delay used some now obsolete components that gave the pedal a really unique sound, extremely warm and fat, however with some noticable noise. A key element for the early Dire Straits live sound.

In "Money For Nothing", Mark uses a wah set almost wide open. You can definitely hear it in live recordings.

Vintage Guitar writes in this article "In crafting his subtle guitar sound, Mark Knopfler relied on one of the most basic musical elements – volume. And the lack of it. From his early days with Dire Straits, he employed a volume pedal, the most simple of guitar 'effects.' He used it, however, in a way never intended."

''But notable effects over the years are a Dan Armstrong Orange Squeezer compressor (1980, early Dire Straits) and a Crowther Hotcake overdrive''
