Title: My dB Control construction
Post by: Crevil on March 28, 2007, 12:19:44 PM
Hey Everybody

Well, I have built a fast schematic on an idea i got the other day.
http://crevil.oelev.dk/dB-control.png

It is actually just a fuzz / overdrive channel and a powerfull booster linked together, then with a simple EQ and a output volume control.

I have not testet this, just trying some ideas, and would like your opinion on the circuit.

If you have some ideas, some cool transistores or anything else, tell me :)

Regards Crevil

Looks nice to me. I'm not an expert when it comes to electronics but I love the idea of having a boost function. 2n5088 are my favourite transistors, they give plenty of gain but are relatively quiet. You could also try some less high gain trannies for less gain or some J201s for more gain.
The only problem I can spot is that the battery isn't automatically turned on by plugging in a jack, nore is there a switch to disconnect the battery.
What programme do you use to draw schematics? It looks really neat.

Yeah, the 2N5088 are really nice, but I'm planning to make a fast circuit and put some sockets in, and then try some diferent transistores I like, and then see what it ends up with.

The problem about about the battery is actually done, but it is mountet to the output instead of the input jack, not really the way to do it, it was suposed to be on the input.

The program is Orland PSpice (Capture), something I got from my work, a really great program, can also simulate all the circuits, making AC sweeps and so on, great when finding some basic values for tone controls.
