The tone switches make a nice difference. I can’t tell a massive difference in the drive switch settings but with more use I’ll see. Still have a big pop and so I will need to fix that.

Somehow I squeezed it into a 1590B and it fired up the first time *yeah*. <br /> <br />All controls work as expected, although I think a A100K pot may work better for volume (as usually). Furthermore I changed the 10uF capacitor at SW 2 - 1 for a 1uF one because the bandwidth switch added a bit too much low end for my taste. <br /> <br />Thanks again for another great layout!

I am getting very loud hum, getting the stomp switch pop and... most of all... it is incredibly loud. I can’t advance volume past 1.<br /><br />Disclosures, which could be causing the problems. First, I used a NE5332 for the IC. Second, I substituted 2n5088’s for the MPSA18’s. Everything else is as specced. I do have voltages if that would help.
