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?
