DIY Tonebender Fuzz

Late last year I started re-learning the guitar. I’ve been learning using online lessons by Justin Guitar. I’ve been slowly upgrading my equipment, buying a small practice amp and a nice PRS SE Standard 24 as rewards for my progress. But the time came to start playing with effects pedals!

Being the sort of person who I am I decided to build a DIY one. After a period of research online I decided to build a basic Fuzz, but using NPN transistors rather than the more traditional PNP transistors to allow me to use a mains adapter. This turned out to be a smart move.

MP38A Germanium NPN Transistor Pin Out

I’ve recently been working on a DIY guitar effects pedal. A lot of these use old vintage parts long since replaced as they are designs from the 60s. This means finding suitable bits on eBay.

Most of the old British/American parts are highly desirable, hard to find and so expensive. What are still pretty easy to get hold of cheaply are old soviet parts. You can usually get 10 or more units for 1 of the old british parts.

The part in question today is the Russian MP38A NPN Germanium Transistor. Ignoring the issue of reliablity and gain matching for a moment 1, just figuring out the pin outs are an issue when the datasheet is in Russian!

  1. As the British parts are rarer, and more valuable they tend to come tested and known working. For the old soviet parts you just buy a bag of 5/10/50 and you get what you get and have to test and rate them your self.

UKG Costuming talk @ MCM Comicon Birmigham

It’s a bit late but last November whilst trooping at MCM Comicon Birmigham I took part in a costuming talk on one of the small stages.

The talk was presented by UKG Commanding officer Gary Hailes and covers an assortment of Star Wars costumes as well as a few from other films.

I’m the Stormtrooper who is up first.

Just a small insight into some of the detail and effort that goes into the costumes we build for both the 501st Legion and Reel Icons.


ElstreeCon 2.0

At the weekend I was lucky enough to be able to return once again to where it all started: Elstree Studios in Borehamwood just 11 miles from home.

This was a troop at ElstreeCon 2.0 in aid of The National Autism Society. Whilst small this was an enjoyable event with a few actors and actresses in attendance.

In the afternoon we were lucky enough to be escorted onto the studio lot, past active sets, to the George Lucas Stage for a few photos!

Trading Card #364

UK Garrison Trading Card 364

One of the more fun things the members of the 501st legion do is create trading cards of themselves in costume. These are available though various channels such as the Detachments (who manage specific costumes) as well as Garrisons (who manage specific geographical areas).

After joining and making a few friends I was given several of these, and some people include them in sales. Sometimes you get one, others 2 with one signed by the member. I soon needed a folder to keep them all.

This year I finally arranged to get my own set made. I went with ordering them through my Garrison as they personalise them to me more. It took me far too long to organise this but I am very happy I eventually managed it.

My cards now take pride of place in the front of my collection.

If any 501st member would like a pair for themselves, please feel free to contact me using the social media links on this site and I’ll send you some.
