    Obsidius preamp problems

    I don't nostra, I ordered specifically what I needed (and a few extra of some components like ic's and some of the caps I get extra) when I was building three pedals. Yeah I'll order some extra when I do. Since mammoth closed I heard about small bear, which is nice cuz the website is better...

    Obsidius preamp problems

    c11 says 472 good call on c8, i had been wondering why that cap was so big anyway and figured i order a weird size one but would still work, turns out i put the wrong one there (checked a lot of the other caps and so far they are correct) so c8 should be saying 221? sadly i cant find a cap that...

    R17 is reading 6.65k while circuit is off so it should be fine

    Obsidius preamp problems

    Volume noon still drive 0 Ic3-1 has signal R17 nope Maxed volume and drive because the volume to test; Ic3-1 works (not like it should but there is signal) R17 very little signal with drive maxed but only if the switch near it is up or down, middle position no

    Obsidius preamp problems

    I'm at work right now but I'll check ic3-1 and I'll turn the drive knob like you had mentioned before as well while testing it. In the earlier testing the back of the pot wasn't touching any of the other solder joints and I actually had the pot bent slightly forward because I looked at the...

    Obsidius preamp problems

    I replaced the switches and they should definitely be working properly. The pedal however still isn't. I ran through some of the tests you've had me do before. Currently the issues I'm having in the test (with blend 0 raw, volume noon, drive 0, switches in middle position) Ic 2-3 nothing...

    The solder points of the switch aren't touching the case, but the the outside of the switch is of course. Is that a bad thing?

    Obsidius preamp problems

    messing up again, clean socket and board with ipa working better, i probably just need to replace the switches, next time i order parts ill grab some so its worth the shipping (though i should probably try hardwiring switch point first)

    Obsidius preamp problems

    I went to go test and it's started working again, once it's messing up again I'll post more. In the meantime I'll go ahead and let you know I've really appreciated your help and sorry for putting you through this. Lol

    Obsidius preamp problems

    Pedal is working for some reason atm, all i did was check the switch with the multimeter before doing these tests 1)Drive is making ic3 louder 2) r17 seems to be same volume on both sides 3)Ic2-2 and 2-3 are 2.79 and 2.75 (still running on battery at 8.5 v Imma play through it for a bit Flick...

    Obsidius preamp problems

    Fair enough. None of the pads lifted. (props to the PCB maker) I hope there's no track cracks. I'll check for any resistors that were touched by the soldering iron cuz I think there was one. Once I get home I'll do all that, probably reflow the ic 2 socket as well.

    Obsidius preamp problems

    Alright so after I get off work I need to test (Making a new number list) 1) test if drive is making ic3 louder 2) see what happens on each side of r17 3) measure ic2-2 and 2-3 (my multimeter wasn't very expensive but it wasn't a free one from harbor freight haha but we'll see how it measures...

    Note to self, don't run delay/looper pedal on a battery while testing, went down to 7 volts

    Obsidius preamp problems

    So because on the circuit board picture it doesn't label which ic (or transistor) is which number I'm gonna clarify as I go through 1) Transistors (not sure which is q1 but guessing the left one, putting both just in case) If looking at the circuit on component side and in reference to the flat...

    Sounds good! Yesterday I didn't get off of work till 9 and today I get off at 6 so I'll do that after then!

    Obsidius preamp problems

    Sounds good, I'm at work right now so I looked for a picture on Google. The picture ooks exactly like mine (got it a long time ago). I do have a delay with a built in short looper so should be good on that.

    Obsidius preamp problems

    Sorry didn't think you meant do it to ground on the jfets too. Oh btw, the toggle switches still seem to change the eq, and when the blend is to the raw signal it goes through fine, but when it's to the distorted side it barely comes through but eq is changed and it's not distorted or as loud as...

    viewing from component side left j201 left to center 4.1 right to center .22 left to right 2.9 right j201 left to center 4.2 right to center .18 left to right 2 (do i have to max out any of the knobs while measuring?)
