[Off Topic] Breadboarding questions

So I'm attempting to breadboard a large muff circuit for the third time, and I'm failing miserably. Is there any way to know if I'm on the correct track when I assemble it? I'd put my output out there after each stage and confirm that the signal was going through, but it was becoming weaker and weaker. Last But Not Least another question This link was provided to this subreddit a while ago, and it appears to have finally found a purpose. This is the connection. Is it feasible to use simply the Basic Parts (1.1) if I go with that option? Is it possible to install the chip on an Arduino UNO, eliminating the need for the Arduino's USB to serial connection and AVR programmer on a breadboard? Because the chip will be programmed on the UNO I already have, I could use this as a non-programmable microcontroller?

Apart from it working, the only way would be to find some obscure omission that causes it not to work. So it would help if you could post a link or two to this 'muff' project. Even better if you can post details here. With hardware like this, it's about schematics and close up images of the hardware, sometimes PCB layouts etc. and the fluky stuff as well. Especially as you built it, and by the way congratulations for that. It's just that, your post involves quite a lot of research to find out what it is about. The chances that there is someone here who knows the answer to your question because they also did it, is slim. But sometimes we can figure it out independently.

Also, by 'the chip' which chip do you mean? Just to save some time.

Yes often large circuits on a solderless bread board fail because the chances of it not making electrical contact are higher with each contact you add.

The solution of course is to make it on strip board all soldered up.

I do know what a big muf is, it's a guitar effects peddle, but what exactly circuit you are trying to follow must remain a misery until you tell us. Let's hope its not an instructables project.

Yes that is to be expected, those amplifiers are common emitter transistors and as such they have a voltage gain of 1 ( but a bigger current gain ) so you don't expect them to get any bigger as it passes through the stages.

Common collector/ emitter follower?

Best to always double-check circuits. They you check for shorts between power rails before powering up with a meter. I also sometimes do a continuity check from the rails to every chip on the board - always helps if every chip is actually getting power!

I'd recommend not bothering with cheap breadboards, high quality breadboards are much better/dependable. Among my faves are the AD series from K&H Manufacturing, featuring 6-point connection strips rather than the usual 5 (makes a big difference to convenience, 5 is a little too restrictive in many circuits).

Need to see the circuit to start figuring this out - did you check chips are getting power?
