this is what a basic Tillman circuit looks like on perfboard http://www.cigarboxnation.com/photo/tillman-pre-my-build

I use the Tillman design with a couple of extra bits to even out the variance in FETs. I put a 50k trimpot in mine where R4 is because the output can be a bit hot otherwise. And if it's a dark-sounding box I add a cap to boost treble as per the info in the link. http://www.till.com/articles/GuitarPreamp/

It's a basic and well-known circuit. So simple you can solder it up on a bit of perfboard. No doubt there will be plenty of people who say there are better designs, but this one suits me fine for a cbg.

i do like the sound you are getting with the tone control... but i would like to see a link to your preamp

As per my Discussion on this, a preamp is still a superior option. You lose about 3db by using my tone pot solution and you still have an impedance problem. This gat would sound even better and drive an amp better if it used my usual preamp. But yeah, if you don't feel able to solder up a preamp circuit like the one I make, this is at least gives you what people have always said could not be done.
