Open Discussion / Re: Headtrip2 patches - you decide!

So having patches is not going to be a problem. I think I've worked out about 15 new ones in the last week or so. I'm also working on some stereo patches for the stereo FV-1 project, too. That comes out this winter.

Here's a preview of one of the stereo patches:

VFE Projects / Re: 422k resistor equivalent for Merman question

You can use either a 422k 1/4W resistor or a 390k+33k in series (1/8W or 1/4W).

Your Vgg voltage is way off. It should read under 1v yet yours is 8v. You need to take a closer look at pin8 of the 3101 and see if there is some kind of soldering bridge or anything that doesn't look right. If you have a different 3101 maybe pop that in and recheck the reading on that pin to see if the clock itself is the issue.

After I looked at it some more I decided that top mounted jacks are probably not going to work for many of the builds. There are too many builds that have ICs and caps that would block proper jack placement. I'd stick to side mount.

Can't remember if I've posted this in the thread but I listen to this every month or two. The Cory Henry keyboard solo is, like, pinnacle musicianship. Lit beyond belief. And, that drums!

I have some flange and chorus patches on an FV-1 build.  In my opinion the FV-1 doesn't do these well, but the delays and reverbs are excellent

After building Megatron TMK, I tend to agree with this.

I find the chorus to be adequate, esp. when used in combination with delay. But, yeah, I don't like the canned flanger sound. Maybe I could do something to make it more interesting, like an envelope controlled rate or depth mod. That could be cool.

I have no problem with anyone using the mbp projects as a basis for personal projects, of course. That goes without saying. The only thing I am protective of is my actual PCB layouts themselves as far as commercial development. Those are protected by copyright. But actual circuit designs, schematics,'s all fair game. I've benefited from numerous circuit designs and so should everyone else.

But, that is a whole lot of work to do for four pots! I probably have the correct long pin pots I could send you if needed.

Lot of good suggestions here so I will use them as a guide. I think the only that probably won't work for the HT2 is tremolo because the wet and dry are different controls. IOW, if you wanted to use a trem you'd have to turn down the dry signal all the way. It's still possible to do, just not ideal. Or, maybe there is a way around it that I don't know about.

Global Annoucements / Re: International shipping available again.

Nice, really happy about this!  :) As someone from Europe that is about to order some PCBs I am wondering how far away are the fall projects? If it's not too long I might just wait with ordering instead of placing two orders.

It'll be 2 or 3 more weeks before those projects are available, I think.

I think it is safe to go ahead an open up international shipping for now. While there are still a few countries USPS is listing as suspended service they have little cross-over with mbp customers. So, ordering is now available worldwide. I will keep the status for refunds to 45 days after ship date for now (outside US and Canada, I mean). Hopefully there will be no problems.

Open Discussion / Headtrip2 patches - you decide!

Things are going to start ramping back up here at mbp very soon but before I put out the next batch of releases I'd like to get suggestions for the Headtrip2.

The HT2 PCB is already complete but the patches are not finalized. There will be 8 available. I have ideas of things I want to include but I'd like to get suggestions in case someone has a really cool idea. Most likely I will put in a couple of patches from the OG Dreamtime and HT1 projects and a couple really cool new ones I have cooking. This leaves the opportunity for you guys to make suggestions on other effects I could include as patches.

So, put in your suggestions for your top 3 or 4 requests for FV-1 patches and I'll see what I can come up with in response. Keep in mind I cannot do things like tap tempo or presets. I'm only looking for suggestions on particular effects that would make a good multi-effect pedal out of the HT2. Also, there are only three knobs to change parameters on each patch so keep that in mind with your requests.

It's not a one size fits all question.

Bipolar: Advantages - generally reduces part count, more headroom (-9v to +9v), reference voltage is the lowest impedance source (ground). Disadvantages - requires a charge pump, so extra cost and adds the possibility of negative interaction with other effects via noise (though usually not a problem).

Unipolar - no extra parts required (ie charge pump). Whether or not the lower headroom of a single supply is a "disadvantage" is dependent on what the circuit does.

Good god if there ever was a time more appropriate for This Is Fine Dog I don't know when. If I had any extra cash I'd probably have that thing on my desk right now!

Open Discussion / Re: Mouser Xicon Resistors New MOQ of 200
« on: September 13, 2020, 08:30:02 PM »
That pretty much screws every Mouser project I've provided for the mbp projects. Ah well, nothing to do about it I guess. You'd think they'd at least go for 10 MOQ but I understand it can be quite time consuming for them to pick out one or two resistors for an order.
