A Bucket Brigade Device (BBD) is an analog electronic circuit (Integrated Circuit Chip) that delays an audio signal by using a series of capacitors to ’hold’ and ’pass’ tiny samples of the signal, much like a line of people passing buckets of water. The signal is moved from one capacitor to the next within each ’Clock Cycle’, and the speed of this transfer can be adjusted to change the Delay Time - typically regulated by a further ’Clock Chip’.

 

In accordance with this feature, the Max Delay...

This article is built on and updated from the 2022 original - with further additions and categories, and a different current--appropriate covershot

The 5 x 5 visual above is not necessarily definitive, but surely largely representative of the best demoers active today - spiralling out from the 3 OG Elder Statesmen / Godfathers of Demos in the centre (Andy, Brett and Mike) and covering 25 of my own favourite demoers. The selection features most of the big names along with many of my own personal ...

The most popular post on this blog to date is ’A Brief Hobbyist Primer on Clipping Diodes’ which has to date been read 117,610  times! It was always on the cards to follow up that article with deep-dives into Capacitors and Resistors too. I wanted to be even more encompassing than before - and go into more detail - and it was a matter of finding the best possible partner and collaborator for that task.

And no one has a deeper exotic-filled parts bucket than my good friend Joe Halliday at Hello ...

So I said I would expand the scope of the 10 Pedal Challenge to Mini and Large Enclosure variants if the original was well received. And in indeed that seems to be the case - with several readers encouraging me in particular to do the Large Pedals Edition.

 

So of course I’ve done the 2 remaining categories - Mini and Large! The Large Pedals were pretty much all obvious choices really and that board largely suggested itself. It was the Mini Pedals version that took the most cogitation!

So a follower on instagram challenged me to shrink my elaborate pedal-chain down to just 10 pedals. My original plan was just to fill a Pedaltrain Nano Max board with 10 compact pedals. But I then decided I should do a Mid-Size variation too, using the Pedaltrain Classic 2 board or thereabouts. I may do further Mini and Large Format editions as a follow-up - depending on how well this article is received!

 

This was a trickier exercise than you would imagine - as I needed to shuffle through ...

So I’ve had a lot of people ask me to explain the reasoning and science behind my 41-strong Pedal-Chain - how it came about, and how it has evolved.

 

The funny thing is that when I got back into guitar in 2016 - following the passing of my two biggest  musical heroes and inspirations - Bowie and Prince - I had intended to keep things very streamlined and simple. As a teenager I struggled to recreate the sounds of my guitar heroes and kind of threw in the towel after a few years of trying and...

This article is in part inspired by my features on ’Mini Pedals State of the Art’, and those various ’12 Degrees’ posts I did at the tail-end of last year.  Moreover I have had quite a few readers recently asking me for my preferred recommended mini pedals on various pedal-chain slots.

 

I last did this sort of exercise 4 years ago - where TC Electronic was kind of the dominant player - covering 8 of those 20 recommendations, with Mooer fairly close with 6 entries, Wampler with 2 and then ...

This is the 4th of my recent ’12 Degrees’ Series - this time moving beyond the boundaries of gain / saturation into the area of modulation. There are of course many more than the 12 modulations I have selected here - there are aliasing, ring modulation and lo-fi signal degeneration effects as well as more complex multi-combo effects, splicers and complex pattern modulators - including for instance the excellent recent Big Ear Albie. Of course the more obscure the category of ...

This is probably the most anticipated of my 12 Degrees roundups - and is a touch more complex and different to the other 2 in the series. Within each category here there can be a huge difference in character and output - for instance with Fuzz Faces going from quite mild to rather searing Meathead and Regulus VIII levels of aggression. So the gradual step up in gain per category doesn’t apply here. And because of circuit variations and differences in components and construction, each and every ...

This edition comes rather hot on the heels of the recent 12 Degrees of Overdrive version as many readers’ inquiries questioned a couple of missing categories there - which I explained would rather figure within the Distortion contingent which is present here in all its glory!

 

As always, these is some considerable amount of grey science at play here - best typified by the Big Muff and Rat circuits - which are both very much distortions as well as fuzz varieties. I have 3 x 12 ...
