Hey, guys. I don't know about you but I've bungled a few of these unforgiving little @#$%$ when trying to get the most usable space inside. I recently sacrificed a 1590A so that I could learn what works and what doesn't.

This isn't the end all be all for measurements on this enclosure. I'm sure there are better setups, I've only been at this a short while. But I thought this might help someone that's about to start their first 1590A as an idea of at least where to drill without trial and error.













Make sure you use the external power jacks, ever extra bit of space inside the enclosure counts.

Use open mono jacks so that you can get them close together, also make sure you bend the lugs so they're parallel with the sides of the enclosure or they'll be in the way of the guitar/amp cable tips and the footswitch.

One thing to watch for is the little metal tab that's part of the Tip connection. Sometimes it sticks out higher than the wafer sections on the jack and could end up touching the enclosure and grounding out. If your jack looks like that, you can do this to slide it down out of the way.



Both of these jacks are good to go.



Here it is all put together.



Anyway, I hope that helps at least 1 person from ruining an enclosure due to a measurement error. Again this is not the end all be all, it's just what I've found to work well. If someone has a better setup, please show me because shoehorning stuff into these enclosures is fun/frustrating and if I can get a few extra MM out of it, that'd be awesome.

Cheers!

Hey, that’s a great tutorial. It’s what diy is all about. I use the drill guides listed on the build docs. I also like to just place the components on and mark the the drill holes. I will always be close but off on a 1590a, they’re just too damn small for my old eyes.
Pedal building is like the opposite of sex.  All the fun stuff happens before you get in the box.

Excellent tutorial!
That is a mighty fancy square too! (I can't afford one--I just looked it up) 
Technical difficulties in abundance.  Please stand by.  ;-)

Thank you. I built using 1590A box just sometime in the last months, and every time I have to measure it like you with very very care.
I converted the inch in mm.

Footswitch: 11,1mm from the base
Power Jack: 11,1mm from the top
Input jack: 14,3mm from the top; 15,1mm from the top
Output jack: 14,3mm from the top; 23,8mm from the top

hmm, cool. How are you keeping the jack lugs from touching the case? ...or the tips from creeping together? Is that a special washer?

Thanks, I used to do the same thing. Place the part and eyeball the center and try to mark it the best I could.

Good call on the MM conversion. Thanks, man.

Hey, dude. The lugs are about 1/8" from the enclosure so, they're fine. You can throw a little tape on there if it gives you peace of mind. I don't understand what you mean about the tips creeping together, the jacks don't move.
