New from Great Eastern FX: the OC201 Preamp

New from Great Eastern FX: the OC201 Preamp

Great Eastern FX Co. has released the limited-edition OC201 Preamp, featuring vintage Mullard OC201 transistors for a unique fuzz sound. Part of the 'Obsolete Devices' series, this pedal combines classic circuits with modern components for optimal tone and reliability.


Boutique British pedal designers GreatEastern FX Co. have released a new pedal. Limited to just 50 units, the OC201 Preamp is an intriguing twist on the familiar two-transistor fuzz circuit, built around a pair of new-old-stock Mullard OC201 transistors.

ā€œThe OC201 is a very early silicon transistor,ā€ company founder David Greeves explains. ā€œIt was actually the first silicon transistor made by Mullard, using the same method as their germanium devices. It’s pretty crude by modern standards, with very low gain and limited bandwidth, but that’s exactly what makes it so great in a fuzz pedal.ā€

This little-known low-gain silicon transistor is responsible for the OC201 Preamp’s palette of sounds, which GreatEastern FX say ranges from dirty boost and garage rock drive sounds up to a raw and richly textured fuzz, all with the excellent volume knob clean-up characteristics this style of fuzz is famous for. The circuit has also been tweaked to deliver a healthy kick of volume to your amp.

This limited-edition pedal is the first in a new series that Great Eastern FX are calling ā€˜Obsolete Devices’. According to the company, the Obsolete Devices series will feature the company’s take on a range of classic circuits, constructed using a mixture of vintage and modern components. It’s a distinct departure from Great Eastern FX’s main range of pedals.

ā€œWith pedals like the Design-a-drive and the XO Variable Crossover, we’re really committed to developing original designs that bring something new to the table,ā€ founder David Greeves explains. ā€œI’m always very conscious of choosing parts that aren’t going to go obsolete so we can go on making the pedals for as long as people want to buy them. But I also love messing around with old parts and classic circuits, which is a totally different mentality. The Obsolete Devices series is basically a way for me to have fun modifying these classic circuits and experimenting with my stash of NOS components, then share the results.

ā€œThe name is a little bit of an inside joke,ā€ he continues. ā€œI think what gets labelled as ā€˜obsolete’ is very subjective. As pedal designers and guitar players, we obsess over obsolete components and what, in any other field, would be considered outdated designs. So the name is a nod to that. I also loved the thought of us coming out with some brand-new Obsolete Devices of our own!ā€

Alongside the pedal’s new-old-stock Mullard OC201 transistors – which are the reason only 50 of them are being made – the OC201 Preamp uses quality modern components, including high-tolerance Dale metal film resistors and WIMA capacitors. GreatEastern FX say that this hybrid approach, using vintage parts where they make the most difference sonically and low-noise modern parts elsewhere, will deliver the best combination of tone and reliability while also keeping the price from spiralling out of control.

The OC201 Preamp will cost Ā£249 in the UK, $299 in the US and €299 in the EU. It’s available now direct from Great Eastern FX Co. and from the following dealers:

  • UK – Andertons
  • Europe – Pedaltown.nl
  • USA – Sound Shoppe NYC
  • Canada – Electric Mojo Guitars

In challenging times, sometimes elemental music, like the late Jessie Mae Hemphill’s raucous Mississippi hill country blues, is the best salve. It reminds us of what’s truly essential––musically, culturally, and emotionally. And provides a restorative and safe place, where we can open up, listen, and experience without judgement. And smile.

This legendary vintage rack unit will inspire you to think about effects with a new perspective.

When guitarists think of effects, we usually jump straight to stompboxes—they’re part of the culture! And besides, footswitches have real benefits when your hands are otherwise occupied. But real-time toggling isn’t always important. In the recording studio, where we’re often crafting sounds for each section of a song individually, there’s little reason to avoid rack gear and its possibilities. Enter the iconic Eventide H3000 (and its massive creative potential).

Valerie June’s songs, thanks to her distinctive vocal timbre and phrasing, and the cosmology of her lyrics, are part of her desire to ā€œco-create a beautiful lifeā€ with the world at large.

The world-traveling cosmic roots rocker calls herself a homebody, but her open-hearted singing and songwriting––in rich display on her new album Owls, Omens, and Oracles––welcomes and embraces inspiration from everything … including the muskrat in her yard.

I don’t think I’ve ever had as much fun in an interview as I did speaking with roots-rock artist Valerie June about her new release, Owls, Omens, and Oracles. At the end of our conversation, after going over schedule by about 15 minutes, her publicist curbed us with a gentle reminder. In fairness, maybe we did spend a bit too much time talking about non-musical things, such as Seinfeld, spirituality, and the fauna around her home in Humboldt, Tennessee.
