Queen’s layered guitar sound was not always built with a wall of amplifiers. For some recordings, Brian May used a small transistor amp John Deacon had assembled in a bookshelf speaker cabinet from salvaged electronics. The story of how Deacon found its circuit board has become part of the amp’s legend—but the surviving accounts differ on both its date and what the board originally came from.
What is the Deacy Amp?
The Deacy Amp is a small, homemade transistor amplifier associated with John Deacon and Brian May. Deacon made it as a compact practice amp; May later used it in the studio with his Red Special guitar and treble booster to record some of Queen’s layered guitar parts. It was one color in his recording palette, not a replacement for his familiar Vox AC30 rig.
Who made it, and was it really found in a skip?
Luthier Greg Fryer says that in a conversation on 22 July 1998, Deacon told him he had found a circuit board in a builder’s skip in London. Fryer’s account describes Deacon as an electronics enthusiast studying for an electronics degree: he noticed wires hanging over the skip, inspected the board, salvaged it and decided it could serve as a small guitar amplifier. He fitted it into a spare bookshelf speaker cabinet, with a battery connection and no controls. This is Deacon’s reported recollection as relayed by Fryer, not an independently verified account. Fryer’s account of the Deacy Amp and his background as a luthier provide the provenance.
The precise date is unsettled. The Vox VBM1 manual places the original amp around 1970 or 1971, while Greg Fryer’s replica booklet says Deacon found the board in early or mid-1972. “Early 1970s” is the safest general description unless the difference between the accounts matters. The board’s former purpose is uncertain, too: Fryer says Deacon thought it might have come from a battery-powered cassette player or radio; the Vox manual says it was almost certainly from a car radio. Neither identification is established as fact. The Vox VBM1 manual and Fryer’s replica booklet preserve the differing accounts.

How did Brian May use the Deacy Amp?
According to Fryer, Deacon brought the little amp to a Queen rehearsal, where May tried it with his handmade Red Special and a treble booster. The booster drove the low-powered amp into a sustained, distorted sound. For stacked guitar harmonies, May told Fryer that the recorded parts “sit together in a more symphonic way” than parts made with his usual stage amps. That description is Fryer’s recollection of what May told him, rather than a direct published quotation from May. Fryer’s account describes the setup and its role.
The point was not simply to make a smaller version of an AC30. The Deacy offered a different recorded texture: a compact transistor amp driven by the booster, with its parts layered alongside other guitar sounds. “More symphonic” is a qualitative description of how those layers blended, not a measured or universally applicable comparison.

What Queen songs feature the Deacy Amp?
Fryer identifies “Procession” and “The Fairy Feller’s Master Stroke” on Queen II as early album examples. He also describes Deacy harmonies across “Dreamer’s Ball,” with an AC30 used for contrast, including in the main solo section. The Vox manual separately names “The Fairy Feller’s Master-stroke” and “Bijou” as recordings where the Deacy sound can be heard. These are source-attributed examples, not a complete equipment log for Queen’s catalogue. Fryer’s account and the VBM1 manual provide the song references.
Was the Deacy Amp used instead of Brian May’s AC30?
No. May used both, in different recording contexts. In a BrianMay.com repost of a Total Guitar interview, May said he often used Deacon’s homemade transistor amp, but specified that “Fat Bottomed Girls” used his Vox AC30 paired with the Red Special. That example makes clear why the Deacy should be understood as one tool in May’s studio palette—not the source of every Queen guitar sound. May’s comments on “Fat Bottomed Girls” distinguish the two rigs.

Can you buy a Deacy Amp today?
The name appears in the history of a commercial Vox product, but that product should not be confused with the original homemade amp. Vox’s historical VBM1 Brian May Special was designed around the Deacy-and-treble-booster system. Its manual lists a 10-watt combo with a 1 × 6.5-inch speaker, gain, tone and volume controls, high- and low-gain inputs, a booster output, recording/headphone output and an external-speaker output. The manual documents the model; it does not establish that it is currently in stock. VBM1 Owner’s Manual.
Vox currently lists two Brian May products, but describes them as signature-tone products rather than Deacy replicas:
