fergs40 Posted November 20 Share Posted November 20 This is the preamp from my new-to-me Excess. Being a curious sort I had a look inside, and am a bit puzzled by what I found. Couple of things: I had expected the preamp to be on a custom circuit board shaped like the cavity rather than a discrete unit like this. Certainly the one in my Passion III is like that, and the wiring diagram on the Vigier website suggests that’s what it should be. Although there is a trim pot (presumably for the hum-cancelling circuit, though I haven’t fiddled with it - yet) it doesn’t line up with the little hole in the cavity cover, and it’s not obvious to me how it could do with the components arranged as they are at the moment. So, does anyone have any thoughts? Or pictures of their Excess preamp (the 9v one) they could share? BTW, regardless of whether it’s the original or not it does everything I would want and expect it to do, so no complaints. But enquiring minds… Thanks as ever, collective.

Mediocre Polymath Posted November 20 Share Posted November 20 I know nothing of Vigiers, but that module looks a lot like the Bartolini NTBT I have installed in one of my basses. Does it have any writing on the sides? The trim pot on my preamp is the overall output trimmer. Quote Link to comment Share on other sites More sharing options...
Doctor J Posted November 20 Share Posted November 20 I'm not sure Vigier ever used CTS pots, I'd also have expected something circuit board based, as you say. Still, that's a clean installation if it is a replacement. Quote Link to comment Share on other sites More sharing options...

Mediocre Polymath Posted November 20 Share Posted November 20 (edited) Here's a pic of my bass's Bartolini gubbins from when I was transferring it all to a new body. The layout of the module is slightly different but the general look is the same, as is the colour coding on the wires. This particular module is more than 20 years old now (yikes) and I don't think they make it anymore, so visual differences wouldn't but surprising.

fergs40 Posted November 20 Author Share Posted November 20 And the prize goes to... @Mediocre Polymath It is indeed a Bartolini, and the same model you had I think. Thanks also to @Doctor J for the link to the pictures of the Excess electronics - those show what I was expecting to find but didn't. But, as I say, happy with what I've got! Thanks all.

It's a lovely preamp. It's not totally uncoloured, but I'm not sure if that's even a thing really. With everything left flat it subtly changes the sound compared to passive in a way I can only describe as "better". I'm currently playing my NTBT-equipped bass while half paying attention to a work teams meeting. Quote Link to comment Share on other sites More sharing options...
