Hey all,
Thanks to all your great help and advice, ive finished designing my Jfet OD   . Its a mid-high gain with good low end definition and low intermodulation. Its quite Marshall'y, and cleans up from the volume control well.
Thanx again for all your help. i couldnt have done it without you lot (whipes tear from eye).
If any of you breadboard it, please tell me what you think. Construcive critism if very welcome!

Congratulations, your OD looks cool.

Thanx, its pretty standard, cascaded jfet stages, but it works...
