If I wanted to get rid of the tone stack I would remove the Bass and Treble pot and also C10, C11, R11, R15. I would leave C7 and R13 and put a bridge across R15, I would adjust R13 value so when the volume pot is on full you have the maximum output you want. R13 and the volume pot forms a...

I always use one of the power supplies that C2CE sells to test and run my pedals, I never have any problem with one of those supplies. They are also very cheap for what they are I think and great for an emergency backup. (keep a few spare) I also use a voltmeter/ammeter from Tayda to check my...

I used 250V 10uF on my first build but all after then have been using 400V 10uF, 400V fit fine and they cost the same as 250V so you might as well get the higher voltage ones. I did use 10uF 450V caps on some builds because they were in front of me but they are a tighter fit to get in there...

Most people run these pedals on 9V with no problems but you can run them on 9V-12V if you want, some people prefer to use 12V because they think there is a difference in tone compared to 9V. The heaters are wired for 12.6V operation but nearly all tubes work fine running on 9V as well, there...

I think Prototype is a better name than Gondwana, mainly because some people will always be writing prototype programs for it to try out. EDIT: After another look at the box and the PCB further up I think Nathan must be a true genius to make that PCB fit in that box, unless there is a PCB he...

Nobelium 2 stage HPF mod. To make the HPF switch have 2 values you have to replace the ON-ON switch with an ON-OFF-ON 3 position switch, remove a small copper trace on the switch side of the PCB that connects terminal 2 to terminal 3 of the switch and then put another capacitor from terminal 1...

My first build had a "Lightning Boy" transformer in it, all pedals since have had the Unagi E4305 transformers in them, I think I have 3 spare Unagi transformers in the parts draw for future builds or maybe to fit into an amp I build. I prefer the the tone of the Unagi.

Absolutely SamuelG, my bad. I was having a bad night and on my 4th dose of oxy when I wrote that, painful bone disease and despite that in 2 weeks I am starting Paramotor lessons where I have to run with a 30kg 25HP 4ft propeller on my back. I will se if I can find it, if not then I will redraw...

I just checked the tubes I have and I think they are the same as what is in the Reverends pedals, they are definitely GE JAN 5814A tubes, thanks Daniel for sharing the supplier with me. DanielG also likes to put a LC filter on the incoming power to the pedal that most likely helps a bit as well...

I like the paint colours that SamuelG used on the Reverend pedal, I wonder if he blessed the pedal before he sold it. Hey Samuel, did you use the 2 stage HPF mod on this one as well? Now if I could just convince Samuel to replace the "Feat The Rev" with C2CE and share the artwork I would be a...

My old mate Picasso recons its this bloke-

I use Kicad to make my PCB's and it has some nice calculators in the program, here is a pic of the list for spacing for different voltages. It lists internal and external layers and also different altitudes and coatings on external layers as well.

There is no point in using that 1N5817 diode on the input, it is only rated at 1 amp and you have a 5 amp supply feeding it. you need a diode that can handle at least 5 amps or use a mosfet as a diode, the mosfet will have less voltage drop across it.

That is very subjective, it is provided for people who would like to experiment with higher voltages. I think the original circuit of some of the pedals had a higher voltage and some people want to boost the voltage to a higher value because they think it might sound a bit better, with my ears...

I think it is the "Momentary Single Throw" (ST) part that makes it not click, there is no contacts that has to latch in or change from NO to NC. You should be able to get more then a single pole (SP) type that does not click as well so DPST and 3PST momentary ones should be fine as well. The P...

This is a good article on how the tremolo circuit works, if you redraw the Mirage Tremolo you will find the timing circuit looks and works like this article. It might come in useful in fault finding your build. https://www.valvewizard.co.uk/trem1.html

I think the biggest problem is finding a momentary soft touch stomp switch that will fit in the space that the normal 3PDT stomp switch sits in, if you can find some then please share a link to them as I would love to try it as well. All the ones I have seen are not soft touch and usually click...

If you are really worried then wear some insulating gloves for added safety, just the normal everyday rubber kitchen gloves will do but if you have some disposable ones like medical people use they should be ok as well and they fit better. You can also stand up and wear some insulating shoes...

I think I have seen that picture on the news once when the police found some funny tomato plants growing in a hidden patch in the bush, they burnt it down and all the neighbours got all happy smiley looks on their faces for the rest of the day, so did the cops.
