Great build. That etch came out really nicely!

Man those look great!! That mod-podge work is way better than I have gotten it in the past, it's really clean and I can see almost no brush strokes.

Thanks man! Low light photography helped hide the brush strokes lol

Dude, that DI bass pre looks the business. I wonder how that would do as a studio bass DI.

I've been using it live direct to the PA and with in-ears and there's a decent bit of background noise. It's not been that bad (or the sound guys would definitely have let me know) but with in-ears you hear everything. Though I've just been using a wall wart to power it, so with a better power supply it'd probably be fine. The goal was to create something good for live or studio use.

I hear ya. I usually grind it out a bit more by circling the drill bit around inside the hole. Great builds by the way.

Yeah I did that a good bit, which helped. But between needing nearly another 1/8" and the tabs that needed filing to fit, I've already bought a stepper bit that goes up to 7/8" lol

Very nice, does the foot-switch go through the pcb?

Yep. Big ol' hole in the middle of the pcb. Momentary switch goes through it and I use an extra plastic washer to space the enclosure doesn't short the back of the board.

Man, that’s are sharp. How do they sound?

The Sunndering sounds great. Lots of EQ range and a ton of volume. The Hot BOD is great too. Not an over the top drive pedal by any means, but dirties up bass very nicely and the clean blend makes it super versatile.

How does the 'mod podging' of paper work, is that some glue stuff to soften the paper or how does that do?

Mod Podge is a water based glue/sealer/finish. Looks like white PVA glue and dries clear. I brush a coat on the back of the paper, place it, then brush a few coats over the top to give it some durability. You could built it up thick and then flat sand it and clear coat it, but I've been too lazy to do all that. Brush strokes haven't been overly noticeable.

Been trying to box up some of my prototype builds lately. First up is my Sunndering bass preamp and DI. It's based on the Sunn S200 preamp, but with JFETs. 3-band EQ + volume control into a simple opamp-based DI. Graphics I just printed on medium weight paper and mod podged onto the enclosure.

(Drilling for the XLR was a PITA since my step bits stop at 3/4" and the hole needed is like .8"

)

Next up is the Hot BOD bass drive, a modified DOD FX91. Used the Demedash Incandenza bypass scheme (555 flipflop to trigger a relay). Faceplate I printed on my resin 3D printer. Built it for a bass player friend who's in a band called "Midwell" so it's appropriately (appunpriately?) named. lol

Gotta go with Earthquaker stuff personally. They're the brand I have the most of both production pedals and DIY clones. EHX would be a close second.

Can it drill enclosures too, or just engrave them?

Theoretically it could do both, but with the stock router (which is just an electric motor with a chuck on it) I don't think I'd try much aluminum carving. I honestly didn't get too deep into the mill because of time and then I got distracted with 3D printers. lol

Very tidy and great build! Do you have a photo of how pcb looked on copper side after CNC? Just curios. How long did it take to mill pcb?

Thanks! I don't remember exactly how long it took. Several hours though, so way longer than etching chemically. I figured out after I milled this that the speed controller for the router wasn't working properly so the cuts weren't clean at all really and had lots of burrs, but it worked perfectly fine. Here's a vid of the mill and a pic of the end result: https://www.instagram.com/p/BzEm6R8H-j8/

Love the clean esthetic! What color/finish is that on the enclosure?

Do you think you'll CNC again or go back to chemicals for etching PCBs?

Thanks! The color is Duplicolor Hampsted Green Metallic. I still have all my etching stuff, so it's always in the back pocket, but I've only etched one board all year. I like the non-chemical nature of the mill, but if I were to do it consistently I think I would want a better mill. The one I have is a cheap kit from BangGood. I've only carved 2 things on it before I needed to re-tighten a few of the bolts and re-calibrate and re-adjust almost everything. I milled this board over a year ago, and I haven't really touched the mill since. I've been getting so many boards professionally fabricated for my store lately that I'm spoiled now. Soldering to bare copper now almost feels barbaric. hahaha

Here's my take on the 1981 Inventions DRV. The board is the same as the layout on my blog but was my guinea pig for carving PCBs on a small tabletop CNC mill. Enclosure is jank 1590B knockoff with waterslide decals. Wired for buffered bypass like the original. I know there's differing opinions on this circuit, but I jammed with it for a good bit after boxing it up. To me it really shines with the gain turned down and volume up. Like a gnarlier Klon, it boosts your signal and adds a nice bit of snarl that responded well to pick attack. It also sounds good with or without the charge pump. Without it loses some headroom, but is still a great sounding dirt box at 9v. And with 18v it just give give you more headroom and a little more spankiness? YMMV, but I dig it.
