Just what I was looking for! I was envisioning doing this with a toggle switch so it's perfect. Thank you!
To my other question, could I run them both at 9V off the same power jack?
Voltage should be the same in parallel, right?
That's right, just have to make sure the power supply can provide enough current for both of them (most power supplies these days have no problem with this - I don't think either of these circuits are current hogs).
My latest - a shamelessly Legend of Zelda-themed VFE Triumvirate, built on the Madbean PCB set and incorporating the bass mods. Shoutout to Brian for hooking me up with a replacement bypass board after I accidentally trashed the first one. I had the box fabricated by Spencer at Amplifyfun and had a great experience, highly recommended.
I didn't have and couldn't find any of the TLE2074 op-amps that this circuit calls for, so I ordered a pair of every different kind of quad op-amp Tayda carries and auditioned them all to find my favourite. Turns out that rolling chips in this pedal is worth the time spent, because the different op-amps give very different results. The go-to TL074 is probably the worst choice here; it gave a very hard-edged distortion along with an intrusive whine originating somewhere in the midrange circuit. Almost every other choice was much improved, giving a more pleasant, softer distortion with less or no whining. I ended up sticking with the LM324, all the good tone and no noise. Now I just have to figure out how best to set all these blasted trimpots...

My last 2.
BB clone / replica and a VFE Pinball SPS version.
I had pcbs made for both. I am licensed by VFE so the board is the exact circuit . My next 2 VFE projects will be the Triumvirate SPS and the Woodchipper SPS. I plan to start the Woodchipper today.
I still have to do lettering / graphics on the Pinball but I was to excited to box it up. There are mods to make it more bass friendly but I am quiet happy with the way it is.
Happy Saturday.

I'd love to try and record some but there's a TON of work I still need to do adjusting this extremely fine-tuneable circuit to where I like it
in the meantime here are a couple of good YouTube demos that might give you a taste:
Just finished this up while waiting for paint to dry. 3 knob Cthulhu on stripboard, 1590b and top jacks. I’m so happy I can do these kinda things.

Second, and probably last Gorva C-65 WTHPF pedal:
Just too much stuff to cram into that box comfortably, and I don't feel like going to smaller and/or more SMT parts. But it works well and would be a much easier build in an S-90 enclosure.

Question for those of you that are more experienced.
Why is it that some effects sound better if you turn your volume down on your bass? It only slightly changes the volume but it makes the effect stand out so much more. I have found this to be with a lot of older circuits. Thanks in advance.

My take on the Varioboost, nice enclosure job from Tayda

i built one of those too 
, only i made my own etched PCB for it:

my latest. it's a modified colorsound overdrive boost with a gemanium transistor clipper and a foot switchable pre gain control. it'scapable of a lot of clean boost and super heavy distortion.
Finished this one up just before I got Covid. Trying to finish up the Triumvirate. Circuit is built and tested, just need to get it boxed up.
Great job as always John. Very nice looking too. I like the color scheme. Bet it sounds great.
Just finished it up. VFE Triumvirate. I think I’m gonna enjoy this one. Has a bunch of trim pots inside for fine tuning but I haven’t made it that far yet.
