No worries, whack a TL072 in there for an XLR output jack and youre printing stupid money. If you phone the artwork in..

Howdy bob!

Think this would probs need a bit more info including a rear shot of the PCB and what transistors did you use? Something with reverse C & E (compared with 5088) could explain the killed signal so early on in the circuit. Could be worth double checking any values hidden by those huge disc caps too.

Amazing looking builds mate, and you're spot on about the HF sounding hifi, love the shootout.

Someone send that video to Xvive as justification for remaking the chips, stat!

Those guts are crazy clean and I'm digging the artwork. Reminds me of Max Headroom

Howdy and welcome back!

The only circuit I know specifically was aimed at down tuned/baritone guitars is the DOD Digitech Boneshaker, so much so that some standard tuning users didn't like it. There's no PCB I know of but there's a vero layout if you're not fearful of offboard wiring - http://dirtboxlayouts.blogspot.com/2019/06/dod-black-arts-boneshaker.html?m=1#comment-form

Happy Birthday Brian 

Stellar work as ever - guts and those pcbs look amazing. One of my favourite pedal demos!

Amazing looking build in and out! Love the graphics, the white finishes it perfectly.

Getting into a band in a big way post teenage years is such a pure pleasure, it's so cool you got to make a pedal for the dude!

Thanks guys! Weirdly enough the knobs were done before the pedal a year or two back, I just don't like throwing stuff away if it could be useful - they're rattle can overspray and the pedal is alcohol inks under a decal.

@Bio77 this is from the original marketing thingy I think - "The CE-3 is an analogue stereo chorus pedal, offering stereo in two modes; a WET A / DRY B, and a WET A / WET B (phase inverted signal)." I did the PCB, I thought I could cut out a lot of the circuit but had to keep adding jfets back in cause of stereo until eventually realised I shoulda just done a 1:1 clone 

A project bourne of needing to do away with Boss' cumbersome form factor, add an unnecessary bunch of parts and ultimately admit that they might, just might know what they're doing over there in Boss HQ however many years ago. The factory schematic has the LFO go really slowly at full tilt so drop that 1M in the LFO down to 470k as I found over on a FSB thread and you're golden.

I am grateful as this pedal showed me the stereo light, I never want to hear mono ever again. Even phone calls, if they're not ringing off two phones at the same time, I won't answer.

Huge thanks to thewintersoldier for hanging in there with my dumbass questions.

Marshall MS2 but I hate that thing. I'm just waiting to see what wins out - my cheap nature not wanting to buy a better test amp or me booting this thing out a window.

Stunning build! Like you say it sounds killer and I had no idea. Thanks for bringing these forgotten gems to more ears, I think Boss' design philosophy has brought them the biggest brand recognition going at the expense of some of their shit flying so far until the radar that it's at home with the mole people.

Or I'm just an uneducated idiot 

That proto layouts a beauty!

Always find them helpful and enjoyable. Like random paragraphs in a build doc it's always a great read!

This one looks fit as, and sounds crackin! Never heard of this beast before but I now need one haha.
