rainbowreality Posted October 12, 2013 Share Posted October 12, 2013 Hi everyone! I'd built a ruby amp with the bassman mods and it's been working fine with my bass with passive pickups by now I've started using a bass with active pickups it doesn't cope at all. It just produces very loud clicks unless the bass is turned almost zero volume and then it's mostly hiss with tiny bit of bass. I'm assuming it's because the input level is just too much. Does anyone know of a mod that will allow active input? Any help or advice very gratefully appreciated! Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted October 12, 2013 Share Posted October 12, 2013 Doesn't sound much like its to do with active pickups. Swap about everything else. Quote Link to comment Share on other sites More sharing options...
BigRedX Posted October 12, 2013 Share Posted October 12, 2013 What happens when you turn down the volume on the bass? Quote Link to comment Share on other sites More sharing options...
rainbowreality Posted October 12, 2013 Author Share Posted October 12, 2013 yep you were right! It was a connection that was at fault, causing the problem. Durrr, assumed it was the active input because it was the new element in the equation! Out of interest though, if I put a switched resistor in line with the volume pot would that work like a volume cutter/active switch? So say would a resistor half the value of the volume pot halve the total volume? Quote Link to comment Share on other sites More sharing options...

[/quote] It would, but its likely to make a hell of a click when you switch it over.

It would depend on the position of the volume control when you threw the switch and whether the pot is linear or logarithmic. Quote Link to comment Share on other sites More sharing options...

rainbowreality Posted October 12, 2013 Author Share Posted October 12, 2013 Do you know any way to avoid that click in a circuit? Apart from not doing it that is! Quote Link to comment Share on other sites More sharing options...
Mr. Foxen Posted October 13, 2013 Share Posted October 13, 2013 Switching pops can be suppressed with a capacitor, but need to pick right value, so it doesn't make a filter. Quote Link to comment Share on other sites More sharing options...

The easiest one is to just use an ON-OFF-ON switch - that central 'OFF' point will be thud free. Quote Link to comment Share on other sites More sharing options...
