Looks really nice. The guts are surprisingly tidy for a multi build. I like the graphics.

Generally, I hope for within two days. I can stand three if it's the only place I can find something. If it's built-to-order, that's a horse of a different color; in that situation, I'd want an approximate build time before ordering.

Great results. That accidental etch should maybe become an on-purpose etch.

I did something similar but with 3PDT switches...that made for an expensive order. 

Looks vaguely retro/industrial. I like it!

Do you find you get a wicked pop when engaging the circuit? I built one recently and would be interested to know if you did anything different with the pull-down resistors.

First class finish! Also like the choice of knobs and green LED.

Looks nice! Like the knob choice.

Looks like a very thoughtfully-laid-out PCB. The knobs are fun! Any sound samples?

Those are like the orthopedic shoe of knobs and you even managed to make them look perfect.

I have high arches! I need the extra support when turning knobs with my toes!

Seriously, though; that is a spectacular build. Graphics are understated and elegant. Guts are super clean.

It's possible the current crop of modelers will recover some value down the road, but if be shocked if they became collectors items.  I could be wrong; it wouldn't be the first time.

If that's true, what do you think the fate of the mega delays and reverbs of today will be? Do you think Strymon, TC, Empress, and Eventide units will hold their value, or will shimmer become pasé like chorus did after the 80's?

To a lesser extent, I even think about that with things like modeling amps.  Those Kemper and AxeFX modelers are very very cool, but when the new models come out, the old ones get devalued quickly.

Vintage gear is weird. Some things are instant classics, other things don't catch on until they are well out of production. Nobody wanted Fender offsets until recently. In the 80's, people would have made fun of you for using spring reverb—that sound is back again! Silvertone and Harmony guitars have always been trash, but people spend stupid money on them now. Gold Foil pickups? Nobody cared five years ago.

There will always be some diehard fan for any given piece of gear. I'm sure in 2050 when the Kemper BiasFX XVII comes out, someone on a forum somewhere will be opining about the good old days of primitive IR when you had to use up two whole rack spaces instead downloading it by Bluetooth to your guitar's on-board hard drive.

Thanks! I've definitely been inspired to be more adventurous after seeing other people's imaginative work on this forum.

Those arcade buttons are sweet! Any chance of a gut shot?

I've always loved the sound of my mahogany-topped dreadnought. It records beautifully, but I've never been able to get an amplified sound I was happy with. Over the years I've tried various arrays of piezo pickups and stereo setups. I finally settled on a magnetic sound hole pickup. It still doesn't sound like the guitar, but it has a cool mutant archtop sound that I also like.



I like playing it into an amp, but I also wanted the option of running it straight through a DI. So I decided to build an on-board preamp to avoid loading down the pickup. The circuit is basically an MXR Micro Amp with a Big Muff style tilt EQ. There is an almost imperceptible scoop in the mid range (welcome in this application) and very robust output level.

The external controls are connected by shielded wire (lug one on both of the controls goes to ground anyway). I was originally planning on mounting the controls inside an enclosure, but I couldn't find pots with long enough threads to get through the enclosure and the side of the guitar.





The gain pot is mounted internally.



I used zip ties for strain relief on the external pots. I went with 3.5mm jacks as opposed to 2.5mm because they are more readily available and a little more robust.



Pickup input at the top. Output to strap button jack on the bottom. The battery is wired externally and sits in its own bag: it's easier to change this way. I wanted the whole thing to be fairly modular. I can swap out the pickup or the preamp without having to solder anything this way.





Drilling those holes was one of the most nerve wracking things I've ever done!

I still think you'll need an active circuit to buffer the combined inputs, but....

If you connect the A->B output to the tip and the B->A output to ring, you could use a DPDT switch to ground them out (to the sleeve). That would leave A->A and B->B. With the DPDT in the other position (open), you'll get A&B->A,B. You'd have to ground the signal in between buffer stages to prevent grounding everything (a total of four buffers) or again use some sort of relay.

The best option for combining signals will probably be a combination of buffers and relays anyway...maybe ditch one of your fuzz pedals or that third delay to make room on your board?
