Last post by jessenator - July 12, 2025, 01:53:39 PMAfter months of companies ghosting me, I finally had an interview yesterday. That feels good.
To placate a broody hen, we got some chicks for her. Then to placate the kids, we got them some chicks to take care of and raise—now they've forgotten about wanting a dog.

I'll do what I can in stoking the conversational fire.

Obviously, the forum has taken a major downturn and that is 100% my fault. It's clear I'm not putting in the work on mbp right now. I've reached a stage of burnout that I just can't seem to recover from. Sixteen years of working solo on a singular "project" has taken a toll and I don't know how to get back on the right side of things. An extended sabbatical would probably be the right thing but I think that would end up pushing mbp further into irrelevancy (in terms of my colleagues and "competitors").
So, I've just been plodding along hoping the stars will align again.
Take care of yourself, it's the most important in the end.

Last post by jimilee - July 12, 2025, 02:38:43 AMIt seems like the hobby has shifted towards straight up clones again. I haven't really seen anything new from fuzzdog either. Barry is putting together 3 and 4 effects on a PCB. I dunno man.

Last post by flanagan0718 - July 11, 2025, 09:19:42 PMSo the "outlaws" are in town for the next few weeks, they're snow birds, and I've been thinking...it's time. I'm gonna have my father in-law help me dig out the electronics storage. You guys may see some stuff go into the BST section so keep your eyes peeled!!
PS Brian, I know I owe you a 3080 IC. I haven't forgotten. I'll DM you for an address.

Does anyone have the images / schematics that were derived here please?
Or the PCB files / layout for like oshpark?
Thanks!

Last post by benh - July 11, 2025, 11:01:07 AMFound a bit of time to spend with the scope, still trying to ascertain wether it's behaving as it should or if I need to dive deeper :-)
Those measurements are made with a 500Hz sine wave in the input, at around 500mVpp (+/- 250mV) it's hot but not necessarily that far from what my son's Stingray will push out, I can try something smaller this week-end). BRASS switch on 1 (mid focus), SENS on max.
* With clean only (brass down to 0), there is a slight distortion. A bit "tube'ey" in fact: the positive half wave is a bit flattened and the negative one a bit pointy (yellow is input, blue is output)
* With brass only (clean down to 0), HARM in position 1 (left), so it should be according to the description "some extra octave in parallel with the EQ", I get this:
FFT:
So you see I get pretty much every integer harmonic under the sun, I don't see any particular "octave" emphasis but maybe that's how it should be.
* With the switch in the "right" position (feeding the full octave to the EQ):
FFT:
Which shows similar harmonics but with descending intensity.
Additional detail, I meantioned earlier, SENS doesn't do much except at the very very beginning of the pot. The first few degrees of turn there is NO signal at all in the "distorted" path. Then it quickly comes up, there is a very small region until around 9 o'clock of variability, and from there it doesn't do a whole lot for the rest of the range. You can see almost no change to the wave on the scope for the bulk of the range of the pot past 9.
On the week-end I'll try to understand a bit of the circuit and poke around with the scope and the audio probe to see if any "path" is obviously bad but I'm not a proper electronician :-) So any hint welcome !
[Edit] Looks like 500mVpp is just way too hot for this circuit. Bringing this down to 200 and the SENS pot has more usable range. Still curious about what you guys think of the rest.

Last post by benh - July 11, 2025, 07:48:16 AMActually for those of you who have one... I suspect something might not be quite right with mine. I'll scope around etc... this weekend but basically when switching HARM from left (octave mix) to right (full octave) what we hear is kind of the same square-wavy fuzz, just less loud.
Is that expected ? I wonder if the octaver is working.
I'll compare with online demos etc...
[Edit] testing with clean bass pot all the way down. Also nothing comes out of brass of sense is 0 which might be normal, but very very little difference from sense at 9'o clock all the way up.
