After that Rat thread I got a little wistful thinking about my old Rat pedal. So, I bought a Mighty Mouse kit from Axe and you Shall Receive and am going to attempt building it tonight. I'm a bit of an amateur solderer, so wish me luck.

Any last minute tips you guys can offer?

Be patient, read instructions carefully. I just screwed up my BYOC Trem because I put the transistors in wrong and am currently trying to find a store that sells desoldering braids...but good luck!

Yep, as said before, take your time, do not rush it. If you are tired, take a break and come back to it later. It is just going to be better when you first hear something you built!:banana:

Well, that was a gigantic waste of my ****ing money.

After double, triple, quadruple checking everything, soldering and re-soldering joints...................it doesn't work. Things finally culminated in me stabbing the pedal many times with my soldering iron.

Good times! :banana:

I got one last christmas, wife picked it up for me. I did the build without problems, actually added a mod to it. But I have a lot expierence with soldering and assembly. If it is still salvageable after the soldering iron attack I would offer to put it together for you. It would only cost you shipping. But then again you could give it one more look over. I find in this case it usually is a bad solder joint, sometimes it is the orientation of a component. Anyway the one that my wife picked up for me turned out pretty good. If you'd like my offer stands just drop me a pm.

Yeah, it's still salvageable. The only thing I managed to really break was the footswitch. The pcb was out of the casing at the time of me finally losing my patience. I woke up this morning still really frustrated about it. I've never worked on something so carefully and for so long and not had it work.

Maybe I was being a little too modest about my soldering skills. I've built a few things here and there and they've always worked. I'm a pretty decent solderer. After thinking about it a bit, I'm coming to the conclusion it was some sort of faulty component, because when I plugged it in, it worked fine when the pedal was off. I got clean signal. But when I turned it on, nothing.

I was pretty meticulous about everything, but especially the orientation of the items that were sensitive to polarization. And I quadruple checked all of my solders to make sure there weren't any bad ones.

So, I guess I'll go out and buy a bunch of new components and start swapping things out until it works. The one thing I wish I knew a LOT better was how to read a schematic so that I could go through the pedal component by component with my multimeter and find exactly where the problem is.

The funniest thing about it all is while I was building it, I just knew it wasn't going to work, despite how carefully I did everything. I guess I've just had too much luck in building things before and my luck ran out. Haha. Ah well. I'll get it working eventually. Thanks so much for the offer, Paul- that's very generous of you. I may take you up on it if I ultimately don't get it working.

I was checking pictures of problem builds that people have with the MM and my board looks set up exactly the same as theirs. After checking for the millionth time, all of my components are in the right place and oriented correctly if they're polarized. This guy seems to be having the exact same problem as me and confirms my suspicion that I got a bum component:

Do any of you know where I can get a replacement footswitch? It doesn't seem like a thing that you can just walk into an electronic parts store and buy, but maybe I can.

Building your own pedals is cool, but VERY frustrating when they don't work. You really have to have a lot of patience when going through the troubleshooting process. I had a hell of a time getting my digital delay working and was pretty certain some component was faulty. The only way I was able to solve the problem was to go over all of the solder joints again and then check the picture of the board, grab my multimeter and check every resistor to see if they measured correctly. Check along the traces and see if you can find spots where the signal is interrupted. Yeah, it sucks, but it IS a new thing for you and I had to learn the hard way too (as has everyone that has built any electronic component of any complexity).

As for the footswitch, there must be a number of places in TO that would carry a DPTP switch (I believe that's what that kit uses IIRC). The places I would look first would be the better quality electronics stores and guitar shops. I wouldn't be surprised if Songbird had some and if they didn't they would probably know where to find them.

Good luck:food-smiley-004:

Oh yeah- good call on the Songbird. I'm gonna turn this frown upside down and use the this as an excuse to learn more about how to use my multimeter properly.

The Source CC (formerly radio shack) should have desoldering braids and the little vacuum suction thingys.

Check your diodes too. If they got overheated during the soldering they can potentially go. Good luck on finding the problem.

That's exactly what I did about 3 months ago :tongue:.

Since then I've learned more and my last build (Octavia clone) went way faster and worked the first time I plugged it in. After having a nightmare build with my slow gear clone I swore I'd never try anything like that again, but I got over it and am going to try fixing my Mesa Boogie with a friend's dad who's a retired electronics repairman.

That's definitely possible, although I was doing a pretty good job soldering yesterday and didn't have to cook stuff to get the solder to take. Although it's far from professional looking, I'd have to say that the soldering I did last night was the best I've ever done. And then after looking at some of the pictures on the BYOC forum of work other people have done I felt even better about it.

Thanks for that link, Paul. I'll give it a good read tomorrow.

I actually just went to The Source yesterday and only found the pump thing. I'm not sure if I'm using it incorrectly, but I'm having a hard time getting all the solder out from the pads...do braids work better at all?

The pumps work ok it is a timing thing, when the solder is hot get as close as you can before pulling the trigger. Braid works well, will clean up the eyelets on the boards better than a pump. I use the pump to take away the bulk then clean it up with the braid. Saves on using so much of the braid.
