My first ruby works great, I decided to see how small I could make my next one. As you can see it is pretty small. So small in fact I could not fit a battery in the box and I had to eliminate one of the pots. Well the bassman mod was perfect because it requires replacing one of the pots.
I had to insulate the headphone jack from the box and now it sounds great. It is very responsive to the volume knobs on my guitar as well as my picking. Louder or stronger picking creates a nice bit of distortion. And lower volume or softer picking plays sparkly clean.
This brings me to my problem, and I'm not sure if it is a problem or by design. The volume pot on my ruby seems to have no effect, I have not tested through a cabinet... I don't have one. Th volume through my headphones is just fixed. I'm thinking I should replace the pot... But I'm wondering of this is just caused by using a headphone jack with a 220pf cap across pins 2 and 3. Or maybe this is just how the headphones work in this circuit... I have a stereo jack with a 47 uf cap.
Should I replace the pot or look t something else? As I said it sounds great... But the fixed volume through headphones has me stumped.
