@Toolmybass thanks for the info. Gentlemen, bare with my line of inquisitiveness for a sec: @Caca de Kick I'm aware of microphonic iso. And was thinking about the residual too. So, when I peered down through the bobbins and the threaded spacers with a magnifying glass, the holes appeared 100% sealed from the coils. How could wax permeate through to get into the slug threads? So I thought: Maybe the slugs were lightly dipped in paraffin, too, ensuring against additional rogue vibration, while also serving to keep the poles stationary as a precautionary redundancy? Any thoughts? One slugs goes in quite easily and I want to avoid any slippage from my heavy handedness. All my saddles used to bottom out on the side closest to me from playing so hard, until a guitar buddy told me about the nail polish drop trick. I've emailed Paul to see what he has to say, but I wanted to check with you all and your experience with working and tweaking them. I'll report back. Peace.
