Twilight Pulse is a well regarded German brand - which makes super versatile and unique Overdrive pedals - from rare and premium components. Northern Stompboxes features two of their finest here in Limited Special Edition Pelham Blue - while the colour looks a little closer to powder blue to me - but that may just be down to the saturation and ambient lighting of the photograph.
We have the Konstante evolved Lightspeed Overdrive with an EP-style Pre Boost. Would be cool to have the anniversary version of that pedal too - which features additional 3-way clipping.
The second pedal is the distinctly unique Proxima MOSFET Drive - which delivers both Overdrive and Fuzzy sounds.
We have a really potent pairing here, while the bestselling Konstante is probably the overall preference. Both are currently available on the Northern Stompboxes Webstore for £185 and £179 respectively. I expect both to sell well!

Konstante Evovled Lightspeed Overdrive Pelham Blue Edition - £185 / €185
Controls - Loud, Gain, Freq, Order, Pre (EP style boost), Drive Footswitch, Pre Footswitch.
This is Konstante. An overdrive based on a modern legend that conquered the speed of light. The Konstante builds on that platform and takes it to a new level of marvel.
With four diodes arranged in an asymmetrical configuration, a higher gain range, and more headroom courtesy of an internal charge pump, the Konstante delivers amp-like response with just the right amount of gain, sustain, and clarity for any setup.
The Konstante also features an EP-style preamp boost circuit hailing from the '60s - '70s for that extra bit of special sauce for fat leads and more saturation.
Both circuits operate independently and are stackable. An order switch brings more versatility to an already versatile Swiss Army knife of a drive pedal.
Proxima MOSFET Overdrive / Fuzz Pelham Blue Edition - £179 / €179
Controls - Gain, Mass, Refine.
The Proxima is a Mosfet Overdrive / Fuzz. The gain range takes you from raw, fat, low-gain breakup to rugged, full-range fuzz. While the concept of overdrive and fuzz in one pedal is not uncommon, the Proxima has something that makes it stand out from the rest.
The circuit is built to make the most of an obsolete Mosfet Opamp that provides a particular fizz to its decay. Coupled with some hand-selected NOS RFT silicon diodes from the German Democratic Republic (GDR/DDR) era, this thing rips like no other.
The result is a double-edged drive pedal that gives you the right amount of breakup, fizz and saturation.
