ANybody built the Umble it looks ok I was going to run it in my effect send to see how it sounds. What are all the trimpots for ?

You can't go wrong with a ROG circuit. I haven't built that one yet, but I recently finished the 18 and it is just great.
The trimmers are bias pots for the FETs. Happy building!

I've not built it, but it'll sound better in front of yer amp. The trimpots are to set the JFet drains at 1/2 the supply voltage for biasing purposes.
