(Apologies if this isn't the correct subforum, I don't post here often.) Ever get that itch to make something? Doesn't even matter what, but you just want to put something together just for the heck of it? That's where I'm at. Every now and then, like many people, I hop onto ebay and see what I can find. And I stumbled onto these things. Preamps, straight from China, and less than $9. So I'm sure they're amazing... But I said "Huh, so they sell those for 9 bucks. Who would have thought!" and moved on with my life. Then, tonight, I want to build a pedal. That's what I decided. I want to bust out my soldering iron, and put a little box together. I dunno, just seems like a fun time. So, how stupid of an idea would it be to buy one of those and modify it a bit, then put it in a box, and have myself a "poor mans preamp pedal?" I don't have a single active bass (And, obviously I'm not putting those in any of my basses)... I also don't have a single pedal. Maybe it could help scratch those two itches here too. Three birds, one stone... It'd let me fool around with those things for only a couple bucks. So, what do you think: Neat way to kill an afternoon, or would I have more fun just throwing the $10 I'd spend on supplies straight into the trash? If you do think it's a totally stupid idea, or if it just wouldn't work at all or whatever, do you have any other ideas for super cheap things I can build? I'd totally be interested if someone was like "Yeah, that's dumb. But here's something neat you can try instead!". Keep in mind, my budget is extremely low. But I'm open to all kinds of suggestions! I'm not really looking for a specific sound or looking to do anything other than just building something, so I'm open to a lot of stuff! Thanks in advance!
