John Britt Daniel

In this picture, Britt's amp rig is seen with his "mystery head" sitting atop his AC30, which he has used as his primary amp when playing with Spoon.

In the 2018 Vintage Guitar interview, Britt Daniel briefly discusses the amplifier and the "mystery head".

My main amp is a small head built by Matt Gilchrist that I plug into the speakers of an AC30. The idea is that if I fly somewhere, I can plug it into any AC30 speakers. On tour, we have a few AC30s with us and I just plug into those. But the Gilchrist head is like an AC30, but made exactly the way I want it. Whenever I rent an AC30, they’re always way too hot-sounding, without detail and finesse; I just want to get a full sound that’s not distorted and crunchy. I was finding that rentals went straight from “off” to way distorted. The Gilchrist is a little mellower and provides more detail and options. I’ve also got a really nice old tweed Princeton from the ’50s.

In this interview for Premier Guitar, Britt Daniel mentioned using a Benson Vinny during recordings for the 2022 album Lucifer on the Sofa. He said:

"We use a lot of [Electro-Harmonix] Memory Man. We also used the JHS Colour Box pedal – it’s like they’re imitating a Neve board, basically; it’s pretty extreme. We used another little amp, this Benson Vinny 1-Watt guitar amp. It’s kind of like the Vox Pathfinder in a way, because it’s so small, but it has a different tone to it."

In an interview for Premier Guitar, Daniel claimed most of his guitar sounds from the 2022 Spoon album "Lucifer on the Sofa" were done with a Vox Pathfinder, which he normally used as a portable amp for radio station performances. He said of the amp:

"When I was working on the songs at home I would usually be playing through the Vox. [When] we were recording, I would have to separate it; we’d put it in a different room because it’s not as loud as the other amps. There was that hump to get over, but it’s got a great sound. You would never know that it’s coming from that tiny little amp."
