Aloha comrades, I got a new pedal. As I just look at it, it looks like it must be really really expensive, some boot-eekish thing or so - it has a purple LED, indicating it being really exotic and stuff, and a raw aluminum housing ... must be so damned good that the guy who made it doesn't need fancy decals or something, ... ... well, I built it. It was a kit from musikding.de, the Birdie, a one transistor circuit, a treble boost. So claiming that I built it is, in this case, the lowest form of having built it ... but it's not over yet, this is a highly addictive entry-level drug! Sounds really nice. Before a drive device, it does what is to be expected - drive it even more. Sounds great into the Big Muff or Sparkledrive - it's just the desired bit more overdriven, a little bit louder of course, but as it doesn't boost the low frequencies as much, it doesn't get muddy. Getting the amp into saturation, of course, goes further with than without it ... that surprisen't anyone. I looked into treble boost pedals and thought, man, I want one, and as they all seem to have a similar circuit, that looks really easy, building it by myself will be more fun and cost less ... so I did so. I came to the conclusion that I won't need a battery connection, therefore I simplified that out of the circuit, and, as the battery is connected via a stereo jack, I put in mono on both ends. The unfancy design won't remain forever, but cosmetics come after function - I might add a tone pot or a switch into it to have the treble in the boosting adjustable ... as the circuit is about the simplest one I know, modifying it doesn't make me afraid. As these are kits, they consist of a few bags of parts and PCBs, which was why I decided to go with a kit and not with just a collection of parts ... would have worked, too, but using a PCB made it easier to fit into the housing, and reduced the amount of work. A more complicated circuit may also benefit from the lower likeihood of mistakes, but in this one, I don't see many opportunities to mess it up. I had the LED connected the wrong way ... SO SAD! ... but everything else worked from the first try. ... the LED makes it sound even cooler, because it is purple. Anyway ... I'll try a few things with it ... with its guts ... and maybe build or buy another housing, or just paint this one in a cool design ... a little box of cast alu isn't that ugly either, I ... I'll see what I do about its looks. ... how about you? What pedals did you build yourself? Bought a kit or all by yourself? Worth it, ain't it?
