Hello again. I finally got around to putting this together and (as I had suspected) it doesn't work properly. Would anyone be able to have a look at the schematic for me and give me some tips re why why it's not working? The most recent schematic is attached. It passes signal so that's a win...

One thing that stands out to me is the gain and band clips are connected to Vref and not ground. I took this idea from the stockade but other TS schematcs have this connected to ground. Should this matter?

Hey I've been working on a Tube Screamer circuit with all of the mods. I posted about it on this thread but I have clearly bitten off more than I can chew. I have put it together and it passes signal so that's a win, however there is no gain. With an audio probe I have tracked the problem to...

I got this thing going properly! Apparently if you put the led in the right way it works as intended. Who knew? D6 on the schematic is a rate LED. Didn't know that since I'm pretty sure the original didnt have one. Pretty neat. I'll put this in a box with my next order and hope the noise goes...

Hi everyone. I’m hoping to make a gonkulator but I need to find an mc1496. I see a few on eBay but I have been burned before. If anyone knows a reputable seller with this that would be awesome. Preferably through home but smd is ok. I see banzai has it but it’s about $50 shipping to...

Yeah the internal trim is a bit of a waste for me. I just have it fully on. Full clockwise (for mine anyway) has max sag. You can actually see the boom LED light up/decrease when you turn it. On my build there is a huge difference in the weight switch with heavy being very saggy and light being...

Well I put this together this afternoon. I won't say it went smoothly but it seems to work. Here is a video. It's very noisy and I'm not sure it works 100%, but it works and sounds pretty much like it should! I'll have to keep working on this.

Mine seems to be working fine. Yellow led is always on for me too. If the red led goes on but doesn’t impact your round I’d look at r22. You may have the wrong value here. I put a trimmer here and found that there was a narrow area that it actually worked. I settled on 1k5 anyway Or you could...

Have you checked every single item in your white layer? Not as a group? I find that I often make a fill in rdg white but the stroke stays in another colour especially is you select everything in a layer/group and change the colour at once. You kind of have to check the fill and stone for...

Why not try a trim pot with pins 2 and 3 connected? I do this a lot when I can’t decide what I like best. Just put a 100k trim where your 100k resistor is and adjust to see what you like best. Or a lower value if you don’t like what you have.

🥸 Well I’ve done the layout already. I’ll double check the schematic tonight (I’m always making silly mistakes) and send it to JLPCB. I’ll let you know if I get it working. If you don’t hear from me then it’s in my drawer of shame.

Of course, thank you. I should have said. And Yes I have upvoted as well. I'm quite interested in this (I'm sure that's obvious though).

I found it here.Never mind.

You mean I won't ever be able to turn the circuit off? Yes I need some attention to that. However my idea is to make this effectively two independent PCBs but on the same board. I'll just connect everything with wires. Had trouble getting my head around the order switching.

Thanks for the comments everyone. I knew I had missed a few things but I'm glad you could all go over this for me. I know I would have been troubleshooting this for a while. So how does this look? - I think the power is connected properly allowing me to switch from 9v to 18v. - Mids opamp...

Thanks for the reply. Yes SW2 is wrong. Robert has suggested something that I will try. You are completey right about SW1.2! I think I have fixed that now. Thanks RE the boost. I can't believe I forgot the power.

Thanks thanks. Good eye. If I put a connection to vref here going to pin 5 when the buffer is off, so you think that will work?

You are probably right. I’ll have to have a think about what I want here.

Thanks. I knew this didn’t look right but couldn’t figure out how to do it.

So I finally got the time to put a rough draft of a schematic together. If anyone wants to have a look at it and see if it all makes sense that would be great. In particular the charge pump. Ideally I'd like to go from 9v to 18v and have this as an external switch. Can I use a SPDT per my...
