Build Reports / Re: Collosalus 24 Build

Last post by Spenzerleehorton - June 25, 2025, 09:23:11 AM

So far these seem like what I need to look at

2n5087 check this is in Q5
Check 500k trimmer as clock
Electrolytic correct values
C23 try bigger value than 62pf = 100pf or lower 47pf
C2 to 51pf
Try link pin 3 to 1 on 5532 to bypass first op amp. Remove r4 and link c3
C1 to 100nf

R19 from 1.4k to 2.4k as per 2015
C11 from 1uf to 100nf

First mistake was the 500k pot was wired wrong!
Will wait for new 4558 and LM 1458 to arrive, then I'll do another voltage sweep.

Nice. Haven't played through one of these yet. Got a demo?

Build Reports / New Misfit build

Last post by lars - June 24, 2025, 10:19:53 PM

Here is my build of the latest Misfit pcb. I jumped at the chance to get the board with a verified CA3260 for the great price Mr. Bean offered. This is an outstanding overdrive/distortion pedal, and yet another great pcb/project to try. I can see why it gets so much love from studios and session players. It just does exactly what you want a dirt pedal to do, without getting in the way of your playing. The 3-band EQ is one of the best I've used on a dirt pedal. The midrange control is especially effective. It can take the pedal from chicken-pickin' clarity, to full-on scooped heavy tones that are borderline metal (I would say, no, this pedal does not do metal).
For the design aesthetic, I'm not really sure what I was going for, other than trying to get inspiration from the original pedal. I guess I wanted that mid-80's "this is a guitar pedal that came with your NES" feel?
It doesn't look like any other pedal I have, that's for sure.

Apologies if this is not the correct subforum, but was just curious if/when the Total Recall might be back in stock.

Im building the collosalus 24 version and noticed the extra IC on input, i had a few silly issues like wiring the wrong pot in the wrong place but apart from wait for IC5 LM1458 (im using a 5532 at the moment to test)
need to go through the volatges again now as i did have the regen pot wired as a 500k rather than a 50k and the sweep/rate as 50k rather than 500k.
regen pot still doesnt seem to do anything and the overall effect isnt very prominent?
the sweep of the phaser is much slower now and starting to sound like the 2015 version.

Build Reports / Collosalus 24 Build

Last post by Spenzerleehorton - June 24, 2025, 02:59:36 PM

Hi Guys,

Looks like im gonna need a little bit of help on this build.
I previously built the 2015 version of Collosalus and was never entirly happy with it, and ive now discovered i had put in all 20k trim pots, so the clock 500k trim was a 20k, still worked but that must be the reason i couldnt dial it in!!

onto this next build, i am waiting on a LM1458 for IC5 but have used a 5532 until it arrives so this also might be why there is a problem, but i thought they were both pretty much the same?

so first problem is that Regen pot doesnt do anything?
the flanging effect doesnt sound at all like before with the 2015 build?
the speed of the LFO is much faster than the previous 2015 build? so needs to be slowed down.

voltages all seem to check out apart from IC5 and IC6, on the pins where it says it varies on mine it doesnt?
my B+ is 15.00v and all other voltages are within 0.5v or closer.

all help would be very much appreciated.

Build Reports / Re: Tape Delay mkII

Just bumping this thread to show appreciation to Aleph Null for some really great designed effects. This one (Tape Delay) was a no-brainer, but I was unaware of some of his other effects .

Open Discussion / Re: Nichicon "Fine gold" caps ...

Those were EOL 3 years ago. Very well could be a bit of oxidation by now.

I wondered. Makes sense. Some of the ancient parts that go in the "verification builds" category suffer similarly.
