dumelow Posted January 12, 2010 Share Posted January 12, 2010 hey, i found a few threads on this but not really with enough info. I have a black russian big muff and I want to rehouse it. Not because size is an issue but because the pots are really noisy when I turn them, the input is a little loose as I lost one of the plastic nuts that go on the outside, meaning that if the cable moves slightly out of place I just get no sound out of it, and because a 9v input that doesnt add any kind of hiss when in use would be awesome. True bypass would be a good idea too if its a simple thing to do. Im pretty sure its common for people to do this but I was wondering if someone could point me in the right place for what parts I would need to purchase and maybe a step by step dummys guide to doing this sort of thing. Ive never modded a pedal in my life. But I refuse to let this pedal retire ive noticed theyre worth quite a bit and Ive always loved the sound it gives me. Any info or advice from someone who has done this sort of thing would be great help Quote Link to comment Share on other sites More sharing options...
dumelow Posted January 12, 2010 Author Share Posted January 12, 2010 (edited) okay so ive been looking at the pedal and i found this www.singlecoil.com/docs/russian_muff.pdf which basicly talks about what I want to do but doesnt go into in great detail so i was wondering if someone could confirm that im right in thinking this... [attachment=40047:P1120018.JPG] okay so thats the pedal im rehousing [attachment=40048:P1120029.JPG] ...these pots on the back read "M10M" with a load of symbols and numbers... im not sure where i can find a better quality version of these could someone point me in the right direction? but all three pots read the same on the back so im guessing theyre all the same? and I can just buy three better ones, and wire them up to replace them? [attachment=40049:P1120028.JPG] ...the red and black power cables coming out the back of the circuitboard... to wire it up to a 9v input do i just buy a 9v input block or something? and just wire that up red and black -> 9v input? or is it more complicated. and after scowling maplin.co.uk i still cant find what i might be looking for and finally... [attachment=40050:P1120030.JPG] could i solder the back(left side on that photo) the small blobs you can see, and then when hot enough ill be able to remove the 1/4" jack inputs and drop in two of these... [url="http://www.maplin.co.uk/Module.aspx?ModuleNo=982"]http://www.maplin.co.uk/Module.aspx?ModuleNo=982[/url] ....and then put all the guts in the appropriate diecast eddystone enclosures you can get from maplin am i way off and this isnt as simple as i think or is this basicly what I need to do. I just gathered from EHX.com that the pedal is already true bypass. any help would be appreciated Edited January 12, 2010 by dumelow Quote Link to comment Share on other sites More sharing options...
Silent Fly Posted January 12, 2010 Share Posted January 12, 2010 If you never modded a pedal in your life, I would recommend you start with something simpler. Unless you have at least some experience in analogue electronics, I wouldn't start with a Black Russian Big Muff rehousing. Especially, if on top of that you plan to add true bypass. Accordingly to the schematics all the pots are 100k linear. You cannot directly replace the 1/4" sockets of the BM with the Maplin BW79L. The BM uses socket for PCBs, Maplin sockets are for wires.

dumelow Posted January 12, 2010 Author Share Posted January 12, 2010 (edited) cheers for the info. i worked as an electrician for a year or two a while ago but it was in motorhomes. So I have dealt with electrics before but obviously a different kettle of fish. I noticed on the EHX website that it says russian muff already have true bypass?? anyways after looking round the true bypass idea looks pretty complicated, so Its just replacing the pots, 1/4" jacks and hopefully swapping for a 9v power input but If thats a more advanced procedure I can live with giving that a miss too. Ill just be putting it in a new box with new pots and new inputs.

Silent Fly Posted January 12, 2010 Share Posted January 12, 2010 These connectors look similar to the ones in the BM. You need stereo connectors. If the PCB dosn't have holes for the central set of contacts (I doubt it) you can cut them for the connectors. Quote Link to comment Share on other sites More sharing options...
dumelow Posted January 12, 2010 Author Share Posted January 12, 2010 (edited) this is great help silent fly. Ive just looked at your website and realised your probably one of the best to talk to about this sort of thing. Would i need to wire up red and black power wires up to one of these for it to work?? [url="http://www.rapidonline.com/Cables-Connectors/Connectors-Mains-Power/DC-Power-Connectors/PCB-Mount-DC-power-sockets/80891"]http://www.rapidonline.com/Cables-Connecto...r-sockets/80891[/url] would that work or am I hoping its too simple?
