  1. Sorry, couldn't help it... build this one to. Fired first time. Works perfect. 2N5458 and BC550, just to be diferent. Cheers!

  3. One of the best distortions that I know!!!

    With 2N5457 that I have for Q1 and Q2 it sounded gated (I had 7.5V on drains), so I used 2 x J113 with Vgs around -1.25 V and Idss around 1.8 mA. Now the drains are around 4.8 V and it sounds fabulous!!! Anyway, better use sockets for Q1 and Q2 from the start.

    For Q5 and Q6 I used BC549C.

    Thank you a lot fuzzhead!
