The 2N1175 Germanium Transformer Boost is a boost pedal from Great Eastern FX Co, part of the maker's Obsolete Devices series. It uses germanium transistors, which the reviewer describes as delivering "smoother, warmer clipping," and it is built to work as an always-on tone enhancer that reaches low-to-mid-gain overdrive at its higher settings1. In that sense it sits between a clean volume push and a light overdrive, rather than being a straight boost that only adds level.
Only 100 units were made and the run is sold out as of the September 2026 review. The reviewed unit was #100, the last of the run1.
Controls
The pedal has two controls, and both shape more than their labels suggest1.
| Control | What it does |
|---|---|
| Transformer (master volume) | Unity gain is around 10 o'clock; noon adds accentuation; around 3 o'clock brings more overdrive; higher settings increase the noise floor1 |
| Low Cut | Sits around 11 o'clock in the reviewer's use, and also affects saturation1 |
The Transformer control is the heart of the pedal. Below unity it can trim level, at 10 o'clock it sits at unity, and past noon it starts to push the front end of the circuit into overdrive, with the Low Cut control tightening the top end and adding to the saturation as it comes up1.
How it sounds and where it sits
Guitar Pedal X's reviewer judged the Transformer Boost a useful addition to a board, reporting that it worked well alongside other gain pedals overall1.
The Transformer Boost was priced at £249, and as of the review it was sold out1. Guitar Pedal X's reviewer praised how it worked with other pedals, describing it as doing "such great things in augmenting various gain pedals, and enriching fuzzes even"1.
That placement matters for players: as an always-on enhancer it can stay on all the time to add body and warmth, and it can also be stacked into distortion and fuzz pedals to enrich them, or run on its own as a light overdrive1.
Availability
The Transformer Boost was priced at £249 and, as of the review, is sold out1. Because it is a limited Obsolete Devices release of 100 units, it is not a standard catalog pedal, and secondhand availability is the practical route for players who want one now.

Questions
Is the Great Eastern FX Co 2N1175 Germanium Transformer Boost sold out?
Yes. Guitar Pedal X's review of 23 September 2026 reports that the pedal was priced at £249 and is sold out. Only 100 units were made in the limited run, and the unit the reviewer examined was number 100 of that run. As a small-batch release from the Obsolete Devices series, it is not a standard catalog product that returns to stock.
How many 2N1175 Germanium Transformer Boost pedals were made?
Only 100 were made, according to Guitar Pedal X's review. The reviewer's own unit was #100, the last of the run. The pedal is part of Great Eastern FX Co's Obsolete Devices series, which the review describes as the maker's latest release in that range at the time.
Where is unity gain on the Transformer control?
Guitar Pedal X's reviewer places unity gain at around 10 o'clock on the Transformer control. Noon adds accentuation, around 3 o'clock brings more overdrive, and settings above that increase the noise floor audibly. The Low Cut control sits around 11 o'clock and also affects saturation.
Does the 2N1175 Transformer Boost get noisy at high settings?
Yes. The reviewer notes that the noise floor increases audibly from around 2 to 3 o'clock onwards on the Transformer control. Below that point, unity gain sits around 10 o'clock and noon adds accentuation, so there is usable range before the noise becomes noticeable.
What is the Obsolete Devices series from Great Eastern FX Co?
Obsolete Devices is the product range from Great Eastern FX Co that the 2N1175 Germanium Transformer Boost belongs to. Guitar Pedal X described the Transformer Boost as the maker's latest Obsolete Devices release in its September 2026 review. The series name reflects the use of components such as germanium transistors.
