Yes, I'm a beginner looking to build on my first project experience. I've just recently built a straight A/B from Tonepad. For an added challenge, I used a very small BUD CU123 enclosure (I posted these to the pictures thread).

I've seen some passive layouts posted, but I haven't seen any "active" layouts meeting my requirements listed in the subject line.

For the powered A/B/Y + tuner:
This one is close, but I would need help adding the tuner switch.

This one has the right configuration, but it's passive. I would need help adding the 3PDT's and LEDs

I saw this one posted in a thread, but it wasn't verified. Does this look correct? Is there another layout somewhere?

I didn't see any powered A/B + tuners posted

I would greatly appreciate some guidance or links to layouts for these two switch configurations. I'd really like to tackle more switches before getting into circuits.

Thanks

Hold on. What do you mean with active ab? If you just want LEDs, that should be pretty easy. If you want buffers, amp shielding, hum reduction, ground lift, etc, that would mean a more elaborate schematic. If your amps work well without all the extra stuff, don't bother. If they hum, you may want to look into adding transformers and things like that.

This is a buffered and hum free design with LEDs but not with a tuner out. I think that tuner out would be as easy as wiring in another jack, you don't even really need a switch, unless you want to silence your guitar with it. Which would be simple as well.

I'm sorry for not be specific. Yes, I only mean with LEDs (nothing extra) and I'm looking for the tuner out to be for silent tuner with an LED to indicate when it's on. Thanks for the Geofex's link, remmelt. I think I did see this one referenced in a few posts as I was searching.

Let me try and propose a drawing. Does this look right for an A/B + tuner out/mute with LEDs?
