Luca at Colombo Audio Electronics remembers fondly the tones generated by the mighty Marshall JMP-1. Fortunately for us he's also an amazing circuit bender and he's applied his considerable skills to producing "the ONE", a pedal that parks you right up next to the Marshall JMP-1 OD1 and OD2 channels with your favourite amp. It's not a clone, it's more of a distortion box designed to put your amp's tone in that JMP-1 sphere. And it does a fine job, I think. It certainly has the grind, midrange focus and dynamic distortion of the original and between the Tone Shape and Mid controls, you can go from smooth to doom and grind to crunch with a couple of easy tweaks. I'm a fan.

![CRAFTROS: SPIRITUS FUZZ - No-Chat Jamcut Demo
https://craftros.com/en/products/spiritus
When I moved house a year or so ago and then got stuck into extensive renovations in this new place, a bunch of stuff that was already overdue for demonstration got shelved and lost in the chaos, much of which Im just starting to unearth now. So firstly an apology to those builders who got left by the wayside but I am going to to get through the lot, albeit a little (or a lot) late. This is the Spiritus Fuzz by Japanese company, Craftros. I dont know much about it or them except that its built and presented way above normal standards and it sounds great - kind of a mix between a fuzz face and muff, I guess.
Its probably better described by the guys who built it so heres the blurb from the website:
This fuzz pedal has a stable usability with an outstanding overdrive.
Its sharpness has a moderate mellowness, and it is balanced with a broad coverage, from playing the guitar as the main focus, to band ensembles.
For the tone control in the 12 o’clock position, the active EQ is flat, and with some excellent adjustment to the circuit, we concentrated on intuitively drawing out the wanted sound while making use of the entire rotational range.
Spiritus provide trackability for the guitar volume and also a one knob EQ that will not fail no matter what position it is in so it won’t get too muffled even when turned down, and it won’t sound weak even with turned up settings.
Elaborate circuit design and high quality parts produce low noise.
