21th Century Big Muff

 A pretty cool lookin¨take on the ol¨Big Muff. The first and the last stage is replaced by a dual op amp, a diode lift switch at the the first clipping stage, a Gain control that biases both of the clipping stages and for the tonestack, a James control network is used for invidual bass and treble controls. .

Back from the wilderness...

 I've been trekking in Lapland (in northenmost Sweden) for the last couple of weeks hence the low activity around here. There is lots of messages in my Blogspot folder, I'll try to walk it thtough it the next coming days. Don't hesitate to hit me up if there is a layout that needs to be tagged or corrected.

Mad Professor Ruby Red Booster

For now, only the booster/overdrive section, might add a separate board for the switchcable bypass buffer later on... 2N5952s is getting really scarce but 2N5457s or 2N5458s is usually a good sub. Just mind the orientation!

Earthbound Audio Pale Mare

 Based on on the mighty Roland Bee Baa with some interesting tweaks.  The transistor part numbers remains unknown but I giess 2N5088s or 2N3904s are good starters to experiment with. Also, the Gate pot can be subbed for a larger value for a wider sweep and the Filter pot can be subbed with a smaller value for a more even sweep.
