Build Reports / Re: Harbinger One success!

Killer job! I've got one of these boards lying around as well buy I need to build up some confidence first.

^Me too!  Nice work.  Turned out great!

Good advice guys.  Thanks!  Much appreciated.  Off to do some research, then likely onto Reverb.  No rush on my part, so happy to at least semi-automate the process.

Hi all.

Disclaimer / lengthy preface: I really don't like selling stuff.  The whole exchange of my stuff for your cash and potential for miscommunication and sideways-ness stresses me out.  Even though I've never had a bad transaction ... it's still a thing for me.  Also, I tend to overthink things.  [The two issues are not unrelated ... as I'm sure you can imagine.]  To date, I've tended to avoid selling by trading things in or giving stuff away or gotten it over with by asking for very little, but occasionally I have something that either isn't trade-in-able or is worth a bit more than I'd like to give away ... especially when I'd like some cash to buy something else (like a neck for a Mustang-style guitar build that I'm collecting parts for).

Anyhow ... this brings us to my question.  What do you think is a reasonable price to ask for used guitar guts? 

I posted this on the TDPRI website:  I'm more comfortable with the folks here, so would appreciate any feedback on the price or any other thoughts on selling used guitar guts.

With that in mind, I also have a used 335-style split-coil wiring harness from jonseyblues (on this page: that was attached to the humbuckers.  Is this something you'd even consider selling or is that plain nutty?  Again, I'd appreciate any feedback.

Odd questions, I know.  It's my growth area! 

Thanks, Bruce.

Do we really need four posts to ask the same question? Once is enough.
In fairness, there are lots of people really curious if the afterlife really exists.

LOL  Fave post.  ;D

Hey ciwi.

The Afterlife is the first 1590A circuit listed on MB's project page:

In stock and well-documented.

Happy building.

Okay.  Feeling a little inspired (?) by the posts here - - I'm going to edit my post and pass on the Bumblebee until I finish building and boxing the other circuits I've started.  Maybe the risk of missing out will motivate me!

Also talked my self out of buying a used Hwy 1 Strat this morning, thinking I need to play my existing guitars more before buying another ... even though it played great and I was pumped to mod the heck out of it a la Robbie Robertson ... minus the bronze dip ...

Moderation is a challenge for me ... but you've probably figured that out already ...

Sweet update!  Looks great and easier access to most commonly needed files.  Nice work!

Ordered a White Horse and an Alpha Dog.

Thanks Brian (and, of course, thanks Peter).

Have to say that I'm with others who are amazed a family in a western, industrialized country needs to raise funds for a basic surgery.  Very thankful for the system where I am.  Still, feeling for Peter and happy to have offered a small contribution.

Tech Help - Projects Page / Re: Delay Biasing for Dummies?
« on: October 23, 2018, 10:57:10 PM »
Thanks for the suggestions guys.  Much appreciated.

Proof I'm a dopey beggar ... it never occurred to me to use my test probe and a looper pedal for biasing.  :-[

With those in play, I think I got the "Clock", "Bias 1" and "Bias 2" trimmers dialed.  Maybe even the "Balance 1", "Balance 2" and "Repeat" trimmers?  No self-oscillation at full CW position on the delay time, mix and repeats pots, but lots of repeats, starting at similar volume to the original signal before fading out.  So that's good, right?

Still, I'm embarrassed to say I have no idea what the "Level" trimmer does since I can't detect an audible change in signal at any test point or at the circuit output no matter how much I tweak it.  I've scrutinized the schematic and it looks like it sets the signal level from one MN3005 to the next (?), but I've very little confidence in my circuit interpretation skills ...

Would any of you familiar with delay circuits ... or maybe even this one ... be able to shed light on the function of the "Level" trimmer and how to set it (link from OP:

Thanks again!

Tech Help - Projects Page / Delay Biasing for Dummies?
« on: October 22, 2018, 10:12:34 PM »
Hi all.

Wondering if there's such a thing as general, but effective instructions for biasing an MN3005 delay ... preferably without an oscilloscope?  If you know of something like that, then I'd really appreciate it if you could point me in the right direction.

Asking because I built up electricb's Analog Delay (Maxon AD-900 /, but there are no biasing instructions.  He was kind enough to provide some reference documents:

- Instructions for MN3008 version from freestompboxes:
- Link to diystompboxes thread about MN3008 version
- MB Dirtbag Deluxe BOM:

... but I'm not getting the values indicated in the instructions for the MN3008 version pretty much at step 1 (i.e. I turned "Clock" trimmer to 7KHz 200Hz, but don't get 110 to 140KHz when I turn the Delay pot CCW.  And step 2 requires an oscilloscope ...


PS.  Lame question #2: how do I find the mid-point of a 25 turn trimmer after it's installed on the board?  They just seem to endlessly spin in either direction?   :-[

That would be the Zener chart on page 7 of the switching board BOM (see  It calls for a 16V zener at D2 on the switching board if you're building a Tractor Beam (i.e, a 1N4745A like this one in the MB cart for the v2 switching board:

Went to see The Proclaimers last night.  I thought they were great.  Very tight and working hard even after all these years.  Definitely not relying on touring the one hit album either. 

Anyhoo, this was the opener:

One girl, one vocal mic, one guitar into a mic'd Pro Junior.  Super-impressed at her composure and vocal range, never mind the finger-style ... which I can't do for the life of me ...

Well, that explains why I couldn't find the pcb website when I googled "ProfessorPoopyPedalPanorama" ...  :o

Isn't the Aquaboy kind of an Aqua-Puss when you add the optional modulation board?  Might have that wrong though, I kind just buy PCBs, stuff parts then try to make sounds like I heard when I was a kid!
