Steddi, Go! - simple tube D.I.

[vigilante398]

For the past several years I've catered largely to bassists, since they tend to be largely underserved in the pedal world. One thing that pretty much every bassist needs is a good sounding D.I., because nobody is going to bring their 8x10 stack to a bar gig for $50. Nobelium is still hands down my best selling project, but it's big and expensive, and is a big jump for someone that wants a tube D.I. but has never dabbled in tube projects before.

So with that in mind, I designed Steddi, Go! It's my answer to the question "what's the simplest, great sounding tube D.I. you can make?" It uses a single 12AX7, has a single knob (volume), and fits in a 1590BBS. I couldn't decide whether the 1/4" output should be a parallel passthrough to feed an amp, IEM, onstage monitor, etc. or if it should be a tap from the tube's output. So I put pads on the board for both, and you can install a jumper for whichever you want to use. Or if you're creative you can probably find room for an SPDT toggle to have both options available.

I have a prototype built up and will get final boards in soon, then I'll get documentation together and make these available.

EDIT: now that I'm looking at it, I kind of want to add a 1/4" source select toggle onto the board. Good thing I haven't placed the order yet.

Interesting!
Is it a single gain stage with direct-coupled cathode follower a la Ampeg SVTDI?

Exactly that, yup.

And it is now up on the C2CE shop page but stock is 0 units until Nathan is ready to go, I can feel the countdown already.
I kept wondering if it was going to have a transformer and now I know it will, as soon as they are ready for sale.

Yeah the main reason I haven't made it available yet is that I'm actually running a little low on transformers at the moment, I may actually have to stop offering them on the website for a bit until I get my next order in about a month.

I have 50 PCBs for Steddi Go on hand now, and the build doc has been started.

Most likely because of greedy people buying your transformers just to have in the spare parts box, I have 2 spare ones at the moment at home.
