Effects Loop

[mrchodito]

Can anybody explain to me how this is used, what it is? I read something about using a keeley delay in the loop and having only the repeats carry a certain sound effect (im assuming this is also in the loop). If i put my phaser in the loop would that basically just be like running phaser after overdrive(crappy IMO)?

Re: Effects Loop

An Effects Loop is built into some amps out there and in basically injects the effected signal in after the preamp so it cuts down on noise that usally comes with using sveral effects in line.

Re: Effects Loop

so if i ran my phaser in the loop;
1. If i was using the first channel it would be like running a phaser after an OD pedal
2. If I was using the second channel it would be like running a phaser normally (before the OD).
That's all there is to it??? Damn, it sounded alot cooler.

Re: Effects Loop

I don't understand the question...where does the OD pedal come in???

Re: Effects Loop

Look, the effect loop is used for stuff like echos because what would happen if you used it in front of th amp?
Basically you get the same signal over and over again, but it gets more silent every time. Now since the preamp drive is affected by the input signal strength, this would mean the echos get less gainy by the time they get weaker.

BUT

if you run it in the effect loop, you already have the processed signal and this is then repeated, meaning you have the same gain/tone, and it's just getting more silent every time, just like an echo should be.

Hope you understand what I mean... it's late over here...

Re: Effects Loop

the Od was referring to my on board overdrive, i should have been specific.

yes that explains the delay part of my question.

Re: Effects Loop

Look at it this way.

It's a way to insert effects between the preamp and power amp. With most modern amps, the preamp shapes your tone and provides distortion/od. The power amp simply raises the resulting signal to the level required to drive a speaker.

So, you can put effects between the guitar and preamp, or between the preamp and poweramp by using the effects loop. The basic decider on what goes where is whether you want it before or after distortion.

Re: Effects Loop

so would 'in the loop' qualify as after distortion? does that apply to all channels? I have only preamp tubes.

The looop does com after the preamp, if you are getting all your crunch from the preamp then yes it woudl be after the crunch BUT that doesn't mean it's gonna sound the same as running an OD pedal after the phase shifter...

Just try things and see what works better for you...there are no real right or wrong answers here...

i was asking if it was the same as running a phase shifter after the OD

More or less.

Running a phase shifter after an OD pedal is different than running it after a distorted preamp, because a preamp will obviously hit the phase pedal with more output.

Before the preamp, you just have the guitar signal, at "instrument" level. Then the preamp boosts it to line level, which works with most rack equipment and some pedals, then the power amp boosts that to drive a speaker.

In short, yes, the sound effect will be more or less the same, assuming your phase shifter will cope with the higher input level.
