The Hungry Robot The Lumen is a state-variable FET-based overdrive pedal with no diode clipping at all. As Eric at Hungry Robot says, " I challenged myself to create an overdrive that used no diode clipping. The most common approach for an overdrive is to send an amplified signal into a clipping section where diodes chop up the waveform and distortion is create. I opted for a more natural approach of cascading FET gain stages. The distortion is created by soaking the transistors with gain. To me, this method provides a more organic, tube-like saturation than a clipping section."
The Lumen's State-Variable Filters
The Hungry Robot The Lumen uses an active tonestack in the form of state-variable filters, commonly found in synths. Offering more clarity and tonal presence than the traditional passive tonestack, the circuit uses 3 filters (low pass, band pass, high pass) to actively amplify each frequency band.
Turn an EQ control all the way down for a flat EQ. Turn it up to boost the chosen frequency range.
The Lumen also features a Clean Blend control. Set it above 12 'o' clock on the dial and it will boost your original signal for added clarity!

Had a few vibes, absolutely loving this one, check the YT demos, lovely satisfying vibe with all the swirly goodness you could hope for. Beautifully made and reasonably priced. Highly recommended - and Jim at Boost is a top guy
I came across the Formula B Fuzz Rangers via online demos on Youtube, and they all sounded so good that I had to get one. Looking online I found the Boost Guitar Pedals website via the Formula B website as a listed UK stockist. Jim was excellent and the pedal arrived when he said it would and it was perfectly packaged. I would have no hesitation in buying any other product from Boost.
As for the Fuzz Rangers, it is a great pedal. I had to work at it a touch to get the sounds I liked from it, but it seems to react really well to different guitars and different amps with adjustments to volume and tone on the guitar and different amp settings. I found it works best into a slightly cranked amp, and volume roll-off on the guitar offers a great variety of sounds from clean to classic fuzz. Thoroughly enjoying the pedal. Well done Jim, great website and a great selection of interesting brands and pedals..... Which one next????
Having used a number of univibe clones over the years this one truly nails the sound for me, it comes with some clever additions in a pedal board friendly size and is excellent value for money. If you want the true sound of the original this pedal delivers.Special thanks to boost Guitar Pedals for putting this deal together so quickly..
I'm still working my way through all the sounds, but so far I'm loving them all.
Each time I think I've got a fav sound I flip the diode switch and there's another one. Great value for a four-in-one fuzz pedal!!
Both modes really useable. The first can get a wooly or starved/wolly sound or more nasally raw sound depending on how you dial it in.
Mode two can be more mid focused and with both switches down it's just a real nice deep, warm wall of fuzz. Great stuff.
Awesome pedal. Does everything from short slaps, to long endless delays, or echo-verb. The infinite delay feature on the button hold is interesting, though if you need a certain sound out of it like that, you have to be okay with the sound that those settings create when the infinite hold feature is off. I’m sure it will be great for recording some interesting textures, but I don’t think I’d use it live, as the infinite hold sounds glitchy and cuts off very quickly at some of the shorter, more subtle delay settings that I use. The art on the pedal is nice, and the build quality is solid. Comes with a carry bag, for some reason, but I can’t complain. A great unit by any standard, but especially good quality and features for the ticket price.
This pedal is simply fantastic.
Great fuzz with a good sweep of control with the guitar volume pot. Cannot get an unlikeable sound through any pickup selection single coil/humbucker.
Added benefit of the Rangemaster included is just lush. I am preferring boosting into the fuzz and use the boost into other drives along the chain.
I am praising this as 2 great pedals in one comfortably sized housing. Amazing!
I have held myself back from purchasing a vibe for years now but I took the plunge on this and I am extremely happy.
The size of the unit is great on my board and pairs with my drives and fuzz amazingly well. I am preferring the flavour of keeping it pre-gain stages on the board.
Simple controls with the added benefit of 2 speeds.
I highly encourage anyone else who was on the fence like me, go for this!
