You'll get a distorted sound, right enough, but it will be a very different beast from typical guitar overdrive/distortion. The Black Ice (and its predecessors) attempt to model amp clipping by bleeding signal peaks to earth.īy putting the diodes into the signal path, you're doing things the other way round - blocking the signal below the peaks, and only letting the peaks through. This doesn't sound like a useful improvement over the traditional circuit. So, you can see, the whole circuit can be replaced by a single diode. However D3 has already shunted any positive voltage higher than Vd to ground, and D1 has blocked any remaining positive voltage from reaching the output. Finally, looking at D2, it will attempt to shunt any positive voltage to ground. D1 does perform a function in this circuit. Now looking at diode D1, on the positive half of the input signal, D1 will block the positive voltage, but on the negative half of the input signal D1 will block the signal until it reaches -Vd, and then the D1 will turn on and allow the signal to pass until absolute value of the input voltage drops below Vd, then the diode will turn off again. However that remaining positive voltage will be blocked by diode D1 and will not appear at the output. On the positive half of the input signal, D3 will turn on at it's forward voltage (+Vd) any voltage over +Vd will be shunted to ground. That means it is shorted out, and it performs no function.
First thing I noticed, diode D4 is grounded on both ends. Vd is the voltage at which any of the diodes will turn on. First, I labeled the diodes, D1 through D4. Do not touch any of the exhisitng wires in the guitar. The basic wiring is the same, but the opposite lead from the marked lead can be left unatatched for a stronger overdrive effect.
(If you saw this before i made this change, disregard the original information). To wire in the version two effect, nothing to the original guitar's wiring needs to be changed. This does however mean that the tone/overdrive will always be on to some extent, and cant be turned alost off like it can be when just a single effect is used.

This allows the tone to be anywhere from full capacitor, to half capacitor half overdrive, to full overdrive. The back of the pot is then grounded as normal. Then, the capacitor is wired to one of the outside contacts and the back of the tone pot, and the overdrive effect to the other contact and the back of the pot. First, wire the signal input for the tone knob into the middle contact. If you want to use the cap along with the overdrive, see below: I prefer its more noticable and agressive tone as compared to the priginal Black Ice circuit, but it does require a more complex hookup.įor the first version, It is wired in place of the capacitor on the tone pot. It also modulates the higher frequencies into the loswer ones. Version two, my version, has a smoother tone than version one, until it is turned up all the way, when it becomes more agressive of a crunch, and plenty of 'wanted unwanted' distortion. It is a little more "hummy" than an overdrive, and the tone is more mellow. It produces an overdrive-type crunch, though it is not exactly like a true overdrive.
Version one is the original Black Ice circuit. I found the amount that the version one effect changed the sound was underwhelming, but my version, when wired in as i specify in the instructable, has a profound change to the guitars sound. Along with building the effect as it was originally supposed to be done, i threw in my own twist. After a bit of research, I found out is was simpler than I first anticipated, and a whole heck of a lot cheaper. He wanted to know if i could make it, as opposed to buying one for 30 dollars. A friend of mine brought to my attention a passive guitar effect, called "Black Ice" which takes the place of the capacitor (or wired with the capacitor) on the tone knob, and when used, gives the guiatr's sound a "crunch" similar to an overdrive.
