I was browsing Tayda for the first time... Anyone use these? Thoughts?

Another pedal finished over the weekend; Earthquaker Terminal Fuzz built on stripboard into a 125B.
This fuzz reacts differently to active vs. passive basses. At first, I wasn't liking the tones I was getting using a passive P-Bass. It sounded strained like it was struggling to push out any signal. So I swapped the stock 2N2222A transistors (~180 hfe) for 2N4401's around 240 hfe. It got fuzzier and sounded less strained, but still had a choked pseudo-gated thing going on.
Plugged my modded Schecter into it next to test how it reacts flipping between active and passive mode. The Terminal really came to life with the active preamp switched on. It no longer sounded choked and now roars and screams like many classic fuzzes.
I wasn't sure it was working correctly until I searched for more demo videos with bass and found videos with sounds that matched my experiences with both active and passive basses.
Painted in an artic color scheme of silver, cobalt and white. Inspired by four back-to-back ice storms in February. Kid painted the cobalt layer.

So has anyone here been successful at combining 2 circuit in parallel in 1 box? I don’t want a blend control,I just want to stack let’s say 2 muffs in one box. There would be 6 pots. 2 volume, 2 tone and 2 sustain. There is more to it than just building 2 circuits and wiring them to the jacks in parallel. Has anyone done this on a diy level.
I've heard good things about the HF press in general, but as with many things related to HF you kind of have to expect to do some work on it for it to work well. I'm not sure I'd flip the switch on any HF machinery until I was convinced it wasn't going to spin itself apart because none of the bolts were tight or anything like that
It's even more impressive that you could size me up from it considering the sloping top tube! Sloping TTs funk up all of the geometry, but I expect that the long stem and seat post are good giveaways. I can't remember the crank length, but I should considering that I built this thing up myself - I used to be one of those bike shop hanger-oners: Good buddies with their number on mech who taught me how to fix just about anything on a bike. Those were the good ol days: shop BBQ's after hours filled with beer and good times after days of riding and talking about and working on bikes.
I'd love to see a photo of your Camerotti if you get the chance - there's nothing quite like old Italian steel

Maybe I think about it. But these are not beginner projects. Many components are soldered in a small space:@disssa
Would you be willing to do a small run of your Traynor boards?
There are interested folks in the thread — two of us have expressed interest outright, but there may be more who just haven't spoken up. I'm interested in both the Monoblock & the TS-60B, @mdalamond is for sure interested in the Monoblock.
@Passinwind Thank you. I feel like a stuck record, forever and always heaping thanks upon you — but you keep crankin' out the coolio for your brothers & sisters here on the board.

The use of sliders makes drilling the housing very difficult. Maybe I could use Rotary Pots instead.
Distortion+ can also be built to DOD 250 specs for milder overdrive. I built one recently with increased input cap of 0.1uF and output cap of 10uF.I hope I can jump in here and ask for some advice. I was just digging through some old gear and found this little board that I bought and forgot about before ever finishing. It took some time to figure out what it even was, but I believe it’s this one from tonepad: tonepad -- file information
It can be used to build an MXR Micro amp or a Distortion +. I’m leaning more towards a distortion/overdrive, but I’m curious if anyone has tips on things I could do to make it work well as a low gain drive for bass. Thanks in advance for advice anyone can share.

Built a Bazz Fuss & Buzz Box combo pedal this weekend. I was looking for a fuzz that would fit into a 1590A and saw the Bazz Fuss could be made more interesting with a toggle switch, similar to Devi's modular designs. Was a tight fit with the toggle switch, even with a tiny 9x5 stripboard.
Bazz Fuss sounds surprisingly good, like a simple fuzz face. Buzz Box sounds similar with some chaotic wreckage distortions added. Tested with 2N5088's and 1N914's. Haven't tried any other transistors or diodes yet. Painted red & yellow on black primer.

I keep pushing my luck with tight fits. Last few solder points take lots of time figuring out an angle of attack that won't accidently melt something else. I've taken my game of Operation skills to new a new level.Well done, great use of space! I panic if I don't have an extra meter of space around every component during the layout process.

Anyone here have any high voltage tube pre-amp schematics or links to kits for DIY? Not starved, low voltage designs but the real HV tubes?
Thx!

The first post from this OLD thread has a schematic of the EHX English Muff'n.Anyone here have any high voltage tube pre-amp schematics or links to kits for DIY? Not starved, low voltage designs but the real HV tubes?
Thx!
Maybe the Frog fits the bill, Alembic F2b style, going to 185+ V.

And the PedalPCB Propolis (TMR Bumble Buzz), an octave fuzz without any knobs. Sounds pretty cool on bass.
No controls --> no graphics. Just a fancy pilot light with a trimmer.

Is anyone here good at making a stripboard layout from a pcb drawing? I have the schematic and pcb layout for the MXR El Grande Bass Fuzz. I would really like to build it and could take a shot at the layout but it would take me a year. If I had the PCB layout in Eagle CAD I would probably just go ahead and have some pcbs made. I don’t have eagle cad nor do I even understand how to use it.
