Steve Cropper

In their October 2008 issue, Steve Cropper told Vintage Guitar Magazine that "Some of the earlier stuff, if you go back to “Green Onions,” I used a little Fender Harvard amp."

The Fender Harvard changed very little between '51 and the end of the tweed era other than a switch from octal preamp tubes to modern small-bottled eqivalents.

I play a Fender The Twin live—usually the red-knob version. They distort too much if you turn them up, and their volume and tone controls are totally different than those on other Fenders, but if you back the bass off and turn the treble up, you’ll get a really good clean sound.

In the October 2008 issue of Vintage Guitar, Steve Cropper said that "Later I moved up to a Super Reverb, and I think the mic was a Neumann U-67. That’s on all kinds of stuff, like “Soul Man.” But on “Dock Of The Bay,” I brought my old Harvard back to play the licks – which, of course, Otis never heard."

"I think it was just on-the-job training. I had this small amp that I recently donated to the Smithsonian – a small Fender Harvard amp – and it came with my first electric guitar that my dad bought me. Used, but the guy threw in an amp with it."

Yes, it was the Victoria 80212, modeled after the Fender Twin. It has a tweed covering, and it’s all handmade, even the vacuum tubes.

In this interview for Fuzz.se, Steve Cropper says

Do you use The Twin in the studio?

• Sometimes I still use my old Quad Reverb - I still use an old Fender Harvard with one ten-inch speaker sometimes, you can hear it on all the old Otis Redding stuff - it’s got a volume and a tone control, and that’s it. It works great for studios

Sounds crazy, but Steve Cropper did play on a modified Peavey 5150, made by Hartley Peavey himself.

Now we’ve got one that Hartley (Peavey) put together for me that is a great amp, but is a big, big outdoor theatre amp. It’s a modified Eddie Van Halen 5150, and they built me a big 2 x 15 inch woofer cabinet. It is just great.

Guitarist Steve Cropper confirmed in an interview with Guy Guitars that he uses the Roland Blues Cube amplifier, stating, "I’ve got a Roland too, the new Roland Blues Cube that they gave me to try that is a real good amp, I’ve used it a lot. So I mix it around quite a bit."

Steve’s silverface Super Reverb is at Stax Studios in Memphis as part of the museum.

During their first UK tour, they didn’t realize their American amps wouldn’t work cause of difference in voltage so they had to use Marshalls.
