James Broonbreed Posted June 14, 2013 Report Share Posted June 14, 2013 Any electronically minded folks fancy taking on a project for me? Firstly I want to swap out the 9v supply for standard boss type socket. Could probably do this myself... Secondly I'd like to build in a drained battery simulator pot or possibly a separate adapter for this purpose. I'm sure this is also easy enough to do but don't want to fuck my muff. Offers or advice both welcome. Cheers Quote Link to comment Share on other sites More sharing options...

Cheers You get a wee adapter plug that lets you connect the muff to a boss type socket.http://www.gak.co.uk/en/visual-sound-3.5mm-converter/31273?gclid=CPPYi_O647cCFSXItAod0VoAmw Even easier than putting in a 9v supply mod!

Cheers Putting in a sag control to simulate a drained is probably easier at the supply end that at the pedal end, better affecting the power on the way in to more accurately reflect what a drained battery does than getting involved with the pedals circuit board. Some power supplies (Voodoo labs) have this built in. or you could build one: http://www.beavisaudio.com/projects/DBS/ Quote Link to comment Share on other sites More sharing options...

Presumably, If I build one of those beavis things, I could just use my existing Moen 9v supply line but use a 3.5mm output on the beavis to feed the muff....

James Broonbreed Posted June 14, 2013 Author Report Share Posted June 14, 2013 I'd also need to reverse the polarity at some stage as the muff has a negative ring... Quote Link to comment Share on other sites More sharing options...
bungle Posted June 14, 2013 Report Share Posted June 14, 2013 What you need to do is charge pump your muff then. http://tagboardeffects.blogspot.co.uk/2013/02/ne555-voltage-inverter.html Quote Link to comment Share on other sites More sharing options...

James Broonbreed Posted June 14, 2013 Author Report Share Posted June 14, 2013 Can I just reverse to polarity on the output of the beavis? Giving my muff a super inverted fucking seems like an awful hassle. Surely you just swap over the ring/tip connections. What's the point in the 555 timer exactly?

James Broonbreed Posted June 14, 2013 Author Report Share Posted June 14, 2013 Aha! Those 3.5mm converters reverse the polarity also. Smashing! Quote Link to comment Share on other sites More sharing options...
bungle Posted June 14, 2013 Report Share Posted June 14, 2013 I don't know what the timer chip does, but I'm pretty sure just swapping the +ve and -ve connectors will fry any polarised caps in the circuit. Are you sure that lead reverses polarity? Quote Link to comment Share on other sites More sharing options...
James Broonbreed Posted June 14, 2013 Author Report Share Posted June 14, 2013 Well, the 1 spot power supply uses regular - tip barrels and this attachment, made by 1 spot, makes it compatible with older pedals that require a 3.5mm + tip so I'm guessing so. I see your point about polarised caps though. Quote Link to comment Share on other sites More sharing options...
bungle Posted June 14, 2013 Report Share Posted June 14, 2013 I'd be pretty careful when trying it out then, I'm not sure what happens when you run positive and negative ground pedals from the same power supply, but I think it'll kill at least one of them, or tear the space time continuum, both are pretty bad.

We're getting WAY too complicated here. Build the sag control and then use any cable that reverses the tip polarity. Job done, pedals safe, space time continuum untorn.Muffs sound awful with a dying battery though - so this whole thread is kinda moot........

Chris Posted June 14, 2013 Report Share Posted June 14, 2013 I use a similar cable with my EH pedals with no issues. Quote Link to comment Share on other sites More sharing options...
