    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...

    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...

    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?)

    Obsidius preamp problems

    Its fine with the noob thing, what I had said previously was to help give an idea of my level of noobness lol. Like, i'm a noob but I have made one perfectly working on first try build from here lol, and have been soldering for awhile, wired my guitars/pickups etc... Ics are correct, its just...

    Obsidius preamp problems

    When I turn on my obsidius preamp the distorted signal doesn't come through (only raw sound and some sizzle). If I flip the toggle switches a million times it will come through, but then I try to flip it to the ones I like (or again at all) it cuts out again. To get it to the setting I like and...

    "obsidius preamp" distortion not working

    yes it is, i took the board out to double check some stuff and its working now, i fixed a short somewhere and double checked the pot connections BUT sometimes when i switch the switches it stops working, and i have to switch it back and forth to work again :(, anyone know why that would be?

    "obsidius preamp" distortion not working

    when i have the blend set to have the distortion sound in it too, the gain knob is just adding some fizz, but it doesnt seem like the signal is actually passing through the distortion part of the circuit, though the switches seem to be effecting the tone. Any common problems/mistakes people have...
