Build Reports / Re: MicroSynth Fuzz
Last post by LaceSensor - October 26, 2025, 02:19:05 PMMy bad for any errors. Ive updated the first page now.
As for missing caps let me know specifically what I have mis-labelled there. thanks
It does jump from C21 to C28 with nothing in between
C28 is added to C19 in parallel. The original part of that filter schematic is not on the original MS (hence the bypass toggle) and is indeed lifted ffrom Aleph Null via a datasheet for a PT2399 delay. Is a multiple feedback Low pass filter. The freuqency can be adjusted via C19 - if you want you can just put a 680pF or whatever your preference is up to about 1.5nF ish and forget C28. I found the 680pF can be a tad limited with bass, its grand with guitar. Hence you can mess around. The pads for C28 could also be used to switch in other caps ?
This was hopefully mostly captured in my build notes, towards the end of the BOM doc
"C19 and C29 are in parallel, and approximate a 680p cap. I found it useful try one cap depending on the tone you prefer. Lower (total) values of C19 and C29 will give "peakier" and harsher treble sounds. Higher values will darken the filter. Try anything from 220p up to 2n2 in total. You can simply put a 680pf cap in either position and call it a day 😊"

As for the wierd values, its what the schematic called for I guess
Cheers

Last post by jimilee - October 26, 2025, 03:36:02 AMQuote from: Mark0614 on October 25, 2025, 11:28:24 PMHiYou may have to email Brian. I don't have it either. 2015 is the earliest I have.
I was going through the box of parts and came across an old Mad Bean PCB for the Smoothie MXR phase 45 clone.
Going through the archives I can only find 2015 layout for the Smoothie, and a more modern layout.

The layout that I have is the one shown in the link.

If you are able to assist me, I would greatly appreciate your help.

Last post by jwin615 - October 25, 2025, 12:25:02 PM@LaceSensor, missing the value for R7 in the BOM and it's in the shadow of a cap in your gut shot so I can't reliability band count. Think there's orange brown and black there but not sure...
And man, you pulled out all the odd all resistor values. I think I used 4-5 values for the first time. 😂
There may be a few caps in the BOM that are non-existent. Had to use my fingers and toes to count them so I may be wrong. I'm about 5 caps and R7 away from being done.
Thanks again for sharing this!

Open Discussion / Re: Check this BYOC news
Last post by matmosphere - October 25, 2025, 08:18:18 AMQuote from: madbean on October 22, 2025, 11:47:19 PMQuote from: matmosphere on October 22, 2025, 04:51:39 AMI am guessing that somebody brought the business from them or something to that effect. I thought smallbear was going to be gone, but they got bought and have reopened (did they even close?)
Pedals have become a big business these days. Google says the market size was $3.6 billion in 2024, but in 2020 it was less than 1 billion, by some estimates only about 500 million. That is a huge amount of growth in the market. It may not have made sense for somebody to buy it a couple of years ago when they were closing up shop but with the pedal market probably doubling in that time maybe somebody decided the math was more in their favor.
Can verify. I made $1B this year.
Sweet, bet those lambo payments are nothing now.
I still don't get why in an industry full of custom guitar and amp builders that charge a premium over factory built stuff (rightfully so), there is no real market for custom pedals. I'll stop the rant now.
Either way, I would be happy to see BYOC back, if for no other reason than it would mean the original owners probably got a nice payday out of selling the business.
