Transformerless directbox

I'll probably just add the switch to overpass the filters, as RobA suggested, and not the Condor, as it will result in a complicated build. I'll post results and build reports when I get to build it!
Thanks!

anxiously awaiting your results!

Me too! I have a lot of my projects waiting to be verified (this one, SMD MXR Dist+, SMD Really Cheap Compressor, my "Wicked Switch", for which I also made a double-sided layout to be fabbed, and the list goes on..). But I hope this will be the first to build, 'cause I need it for some recordings. Hopefully, I'll finish it late September.

Another nice simple one for you here as well:

Also, Jack Orman (AMZ Muzique guy) sells PCB's for his DI box circuit.

He is a good guy, and somewhat of a DIY legend (creator of fabled Minibooster and Mosfetbooster circuits) so is worth supporting!

So I'm going with the AMZ direct box and a jmk pcb for the headphone amp. In a multi effect box, can I come off of the last effect and into a dpdt on/on switch and have that toggle between the headphone amp and the transformerless direct box and both of those be wired to the output jack? I don't know how I get myself into these things, but a friend asked me to build this monstrosity for him. 4 effects, a headphone amp and a direct box.

How many output jack would there be?
- (asymmetric) regular pedal out (before DI box and phone amp)
- (stereo?) phones
- symmetric DI out: 1 TRS and 1 XLR, or only one?

No need for a switch then. Or are any of these outputs to be combined? Are you sure he doesn't want DI and phones at the same time (for direct monitoring perhaps)?

And you surely had a look at http://www.madbeanpedals.com/forum/index.php?topic=10123.0 already?
It provides cab sim, headphone amp (stereo) and DI out.

This looks like what my goal is, 3 outs. DI will be XLR, regular pedal out and head phone out.

Bump for the dumb guy. Would I need a buffer / splitter  off the last effect?
