How do you Short a Diode,Resistor

[dumbassbob]

I started to do alittle modding on a SD-1 and a DS-1 But on some ideas it said to short it out What do they mean and wont it hurt the rest of the curcuit

OK, maybe I am dumb, but what are SD1 and DS1? A schematic would let us look at your situation.

Short it out means connect one end to the other. IN experiments, that usually meabs a clip wire connected to each end. permanent? Then tack a wire from one end to the other end of it, or replace it with a piece of wire.

Won't it hurt it? Well, hurt what? A diode sitting there without a circuit around it is fine shorted or not. If the diode is a rectifier in the power supply, then certainly shorting it out will cause damage. But what if we have three diodes in series to make a volt and a half voltage drop and we want to reduce that to 1 volt, then shorting across one of the diodes does exactly that.

And without knowing what all these mods might be, perhaps other changes they are making require point A be connected to point B and there is a diode there now that no longer is needed.


It is always about the circuit, not the parts.

Enzo, they are distortion pedals. The diodes to be shorted are likely I guess to be limiters or signal clippiing.

A Boss SD-1 has 3 diodes (2+1) in the feedback path of an op-amp. Shorting one of the diodes in the path where there are two in series will essentially turn the SD-1 into a TS9...sort of, producing a more compressed sound with somewhat lower output level.

In this instance, "shorting" essentially means bypassing by providing a 0-ohm path to follow, in parallel to the diode. When the electrons have a choice of a zero-ohm straight wire path and a diode, they will pick the wire over the diode every time.

Note that shorting/shunting/bypassing a diode in the path where there is a single such diode (instead of 2) is NOT the sort of thing you want to do. Shorting either diode in your DS-1 will result in no output whatsoever. Shorting the single diode in the clipping circuit of the SD-1 will result in no distortion and fairly low output, since it will convert the clipping stage into a unity-gain stage.

Shorting

I just really wanted to know what it ment.I have already put a GE in the #3 diode on the SD-1 and changed all the Caps to MF. removed C-6 ect.Same with the DS-1 I put GE inplace of reg. diodes and changed all the Coup and tone caps to metal film panasonicsI just wasnt sure that shorting ment bypass thanks for your time.
