Impedance on an on board preamp

[Owen]

Like most of us here, I have been through way too much kit. I only realised after the fact that much of what is out there does the same thing. Especially once the guitarmageddon kicks in and any subtlety is steamrollered. 

 

One preamp which did something different was the "Z" (impedance) switch on an Audere preamp I had and, foolishly, sold because the next thing caught my attention. I have never followed it up because Audere became unavailable in the UK. 

 

I have just read that they are closing down and this got me wondering. Is a standalone Z switch possible? Would it go before a preamp? Who would make one? Does anyone make one? 

 

When I activated it things got gruntier, and it was good grunt. Obviously I had turned the internal pot full on becuause that is what they are for. I have now reached the end of my technical expertise. 

 

Any ideas?

If I remember correctly, it was Bill Lawrence's idea to start toying with an impedance changing switch.

 

I need to check, but I'm quite sure I have some schematics somewhere...

 

And I found the explanations from the guy himself, see below.

Worth reading, really.

Thanks Tony. There were words that look familiar there. But that is not where my skillset lies, sadly. But the conversation has started! And that is the important bit.

 

I know that G&L do something..... capacitor across one coil.. something.... with their L1000 pickup which provides a HEFTY amount of grunt. Is anyone doing this kind of thing commercially as a drop in that I have missed? A combination of that G&L option on a Jazz could be interesting. Obv, it would not do the G&L thang, but it could be an interesting flavour. Also the Audere thang would be great.
