General Questions / Chunk Chunk Version question
April 26, 2016, 07:06:26 AM
Hi Guys,

I built a couple of Madbean pedals a while ago (3 x Neotrino's and a Dirt Box) and have had the 2011 version Chunk Chunk boards since then.

I notice that the new Chunk Chunk is significantly different in layout. Whats the differences?

It's not the resistors, its the Caps. Granted I am buying enough caps for 2 pedals, but it still seems a bit pricey.

Priced up some of the components today using Farnell's website. Jeez this is an expensive build. Dont remember the other builds being as pricey as this. have the prices of components risen substantially over the last 12 months?

Dr Tweaks says he can source all the bits so I'll give him a go.

General Questions / reverse polarity protection diodes
September 07, 2011, 02:02:22 PM
HI,

The Chunk Chunk has a 1N4004 as reverse polarity protection. Could I sub this with a 1N4001?

As I see it the difference is the voltage 50v (1N4004) as opposed to 30v (1N4001).

I cant get 1N4004 in UK.

I got the shipping notice this morning so I guess I should see my boards in a week or so. Emailed the good Doctor to see if he can stock up on some of the lesser used value components, so I can source everything from him.

I've ordered a couple of Madbeans Chunk Chunk boards today. Winters coming and I'm going to need something to keep me occupied during the long dark nights.

I already have a Biyang Metal End King distortion Pedal, but it doesnt  give me that ripping afterburner type distortion that is typical of high gain amps like the Mesa Boogie rectifiers (like I heard at the Alterbridge gig in October last year).

The other 2 Madbean pedals I've built are working well, so I guess its time to go through my rite of passage.

Will get my bits from Dr Tweak or Farnell here in the UK.

Thats is all.......

Indeed,
But it's gone to a good home where it will be loved and cherised in a way befitting my first born. Currently starring a PRS USA Custom 22 and a Mesa Boogie Mk iii.

Hey guys,

one of those red boards misteriously made its way over here and so I had no choice but to make a Violet Rams head version. Sounds pretty cool.

It's right what they say - you can never get enough of a good muff!!

Used bits from a couple of sources over here, including a guy called Dr Tweak. He does an enclosure kit with all the jacks, Leds, bezel and switches for a really good price. All you need is to get your pots, knobs and then drop your board in and off you go.

Just thought I'd update you all on the progress. Neutrino Burst #1 is now in the ownership of one of my friends. He liked it so much when I let him borrow it that I ended up giving it to him as a birthday present.

I have since built another Burst pedal, using the last of the 3 boards I picked up from Madbean, and I think this one sounds just a little better than my original.

The Black pedal needs a bit of tlc as I think its developed a short somewhere. Started off fully functional, but then started to each battery power, and now it doesnt work at all when the back is on.

I also built a Gruntbox for some vintage fuzz, which might come in extremely useful.

I also have a valve amp on the way for some filthy tube action.

Hi Madbean, not been around (here) for a while. Sorry to hear of your loss. Grandad's are 'special' for boys. I was gutted when I lost mine a couple of years ago. My 8YO boy carries his name on. As well as inheriting his name, we've found out this summer that he has also inherited his passion for fishing.

Please accept my belated condolences on behalf of your family.

I just let the board float and isolate it with a square of white foam, similar to what some consumer electronics get packed in.

Just finished my Black Neutrinon. See my build report.

Build Reports / Neutrino No2 'Black' version
June 24, 2010, 10:13:59 PM
Hi boys and girls,

I've just finished Neutrino number 2 to the Black specification using a 4558 op amp.

Its not got as much gain as the bright version that I built, and strangley it seems to be brighter - not sure about that. Although I think I may have used the Black version C6 value in the bright Spec pedal. That one also has the LM1458 IC.

I cant do a side by side comparison as I let my mate borrow it for his PRS custom 22 and Mesa Boogie Mark 3. I've spoken to him tonight and I might have trouble getting it back.

The sound is very old school, maybe a bit fuzzy but not a full on in your face overdriven distortion. Very 1960s, I'm trying to put my finger on what it reminds me of but I cant place it.

Decided to leave the enclosure as is, the bare metal 'dirty' finish is somehow appealling.
