The ThorpyFX EAO PINK version is a germanium fuzz built on the Burns Buzzaround circuit, which the maker calls "the venerable Burns Buzzaround" and describes as one of his favorite germanium circuits ever1. The Buzzaround itself is a vintage germanium fuzz from the late '60s / early '70s, rare today, and originally a three-can germanium fuzz box sold under the Baldwin Burns name23. EAO stands for Explodes All at Once4.
Sound and character
ThorpyFX does not describe the EAO as a subtle pedal. In the maker's words4:
"It doesn't clean up, its not subtle, it has a savagery far ahead of its time. they are instant plug in and grin pedals."
Players looking for a fuzz that rolls back to a clean tone with the guitar volume will not find that here; the design leans into full, unclean germanium saturation. For other approaches to germanium fuzz from the same maker, see the ThorpyFX EAO main page or the wider range of Fuzz Pedals4.
Build and power
The Pink version is built the old way. ThorpyFX states the internals use old school turret construction, a hand-wired method, with NOS germanium PNP transistors doing the fuzzing4. The enclosure is part of the appeal: reproductions of the classic folded steel mkI TB style enclosures, finished in pink powdercoat with teal graphics4.
What the maker specifies for this pedal:
- Circuit basis: Burns Buzzaround germanium fuzz1
- Transistors: NOS germanium PNP4
- Wiring: old school turret construction4
- Enclosure: folded steel mkI TB style reproduction, pink powdercoat with teal graphics4
- Power: battery only, no DC jack4
- Battery isolation: power cutoff switch on the middle pot4
These are battery only pedals4. There is no DC jack for a power supply. Because a battery cannot be unplugged like a power lead, ThorpyFX added a power cutoff switch on the middle pot so the battery can be disconnected when the pedal is not in use4.

Questions
What does EAO stand for?
EAO stands for Explodes All at Once. ThorpyFX uses the name for its line of fuzzes built on the Burns Buzzaround circuit, a germanium design from the late 1960s. The maker describes the pedals as instant plug in and grin pedals, with a savagery far ahead of their time.
Can the ThorpyFX EAO run on a power supply?
No. ThorpyFX states that the Pink version EAO pedals are battery only. Because germanium PNP circuits have different power requirements from standard negative-ground pedals, the maker fitted a power cutoff switch on the middle pot so the battery can be disconnected when the pedal is not in use.
How many Pink EAO pedals were made?
The Pink version is a small limited run. As of the maker's product page dated 25 October 2026, ThorpyFX had just 3 of these available, with around a 4 week lead time on orders.
What transistors does the EAO use?
The EAO Pink version uses NOS germanium PNP transistors, meaning new old stock parts rather than current production. The internals are built using old school turret construction, a hand-wired method associated with vintage pedal and amplifier builds.
How much does the ThorpyFX EAO Pink cost?
The list price on the ThorpyFX product page dated 25 October 2026 is £449.00 GBP. The maker also notes around a 4 week lead time on these pedals.
