Ibanez BS10 Bass Stack

There you go John. We'll never have enough bass designs... This one is basically a Rat for bass.

Thanks to John, this one is now verified. Which also means that the LM7 and FC10 should be safe to build.

Ibanez LM7 L.A. Metal (layout v2)

Another redux drawn from Dirk's schematic..

Ibanez FC10 Fatcat (layout v2)

Ok. As the original layout for this circuit was originally drawn from a bad schematic and altered later, i thought it would be a good idea to redraw this from a trusted (Dirk Hendrik's) schematic with original buffering in tact. I also removed the old one from the archives... As this Rat adaptation shares the original board with LM7 and BS10, those are on their way too.

Info from the database:
A wide range of distortion sounds, a fat sound, and plenty of sustain characterize the Fat-Cat Distortion. Unlike typical overdrive units, when high gain settings are used, the fatness remains, allowing the FC10 to be equally effective on lead or rhythm guitar.

Like the TS10 and DS10, the FC10 gives extreme level boosts to incoming signals, creating an overdrive distortion effect. Enough gain is available to overdrive even weak signals, such as single-coil type guitars and low sustain/fest decay tones (bringing them up to a high sustain level).

To get the Fat-Cat "growling" distortion sound, turn the distortion control up high, while keeping the level control low enough to limit additional overdrive at the input of the amp. The tone control can be used to add harmonics for brightness and controlled feedback. High tone settings increase attack articulation, especially helpful on guitars with humbucking pickups.

DOD 555 Performer Distortion

The orginal unit uses two 9V batteries and electronic swithing. I removed the latter, but left the supply voltage wanting the 18V. With this, i also left the (possibly) destructive polarity protection method in tact. For the supply, one can use two batteries or add a small daughter board to pump the standard 9V voltage close to desired 18V. That pump would be something like this or this.

DOD Studio Bifet Preamp / 410

Without the pseudo-balanced output and adapted to work as a stompbox. Not really sure if this is worth a build as it is supposed to be not that loud. Simple design with low parts count, so it might be nice thing to experiment on... The pot tapers are not mentioned on the schematic i found, but i suspect that linear should work well enough for both.
