I have a Kiloton 5 that I got a couple months ago. My other main bass is a G&L LB100. Regarding settings, you will notice the series setting (switch pointed towards the neck) is significantly louder than any other bass you own. This is my favorite setting, but it does drive the front end of my amp harder and pushes into overdrive, sometimes not intended. To correct this, I set my amp to the ideal gain level for my K5 in series, and then if I use another setting or another bass, I have a clean boost pedal I just to bring my input gain to an equal level of the K5 in series.
I also find the single coil setting on the K5 (middle switch position) to sound great. It has more clarity, but does produce some hum since it's single coil. Personally, I am not a fan of the parallel setting, but that's just me!
