Peavey 3 chord hookup + pedal effects

Jerome Hawkes · From: Fayetteville, North Carolina, USA

i've got a session 500 and been using the 3 chord hookup for the VP - i just got a RV-5 and am wondering where in the chain to put this. i have hooked it up thru the pre send-return, and it works, but i get some weird faint knock right after i attack a note - its an old amp and it may be something in the loop. is that the best way or do you run these pedals in line somewhere.

I also use the 3 cord method with my Session 500, and I stick my delay unit after my volume pedal.
I use the patch on the front panel, going into the volume pedal, then out from the volume pedal into my delay unit, then out from the delay into the 'from pedal' input on the patch

Some people don't like the delay after the volume pedal, but I prefer it that way Very Happy

I use the three wire system, (guitar directly to the 500, then amp to pedal and back on the front panel) but I place the RV-3 or Lexicon reverb after the EQ section. On the back, Pre-Amp out into the RV-3 and RV- out back to the power amp in. I think is is better to Not EQ the reverb or any delay signals.

Note that the RV-3 Is designed to be used in the instrument line so keep an eye on the gain settings so as not to over drive the pedal. You could try input #2 on the 500 also) The Lexicon is basically line level and is a little easier to use in this hook-up

Knowing just enough about electronics to not blow anything up - I had assumed that pedals were to be used in the primary signal before the amp and rack effects for the effects loop on the amp. I know I tried running my mpx100 inline with my old 70s Evans fet, as it didn't have an effectsloop and it was all distorted

A quick follow up on three wires.

You guitar pick up puts out a small signal, it is then feed through the "pot" in the pedal and on to the amp. (assuming no effects, etc.) If the pot were to make any hum, or scratching, that noise is added to the guitar signal and amplified by the pre-amp and is now part of your guitar sound.

If you feed the guitar directly to the pre-amp on the Peavey, the signal is amplified by 20 DB or 100 times, give or take the gain setting. If this pre-amp signal is feed back to the volume pot and the pot does add some scratching noise, that noise is now 100 times smaller than the guitar signal. So any noise added by the pot or cables is reduced by the gain of the pre-amp in relation to the signal.

A second reason for the three wire system, the pick-up is designed to "see" a high impedance such as the input to your guitar amp or your 500K pot in the pedal. However, as you lower the volume on the pedal the pot in the pedal is going lower than 500K going all the way to zero. As the pot resistance is lowered, it takes some of the high frequencies with it and your low volume signal sounds muddy and lacks sparkle. This is the reason that "Black Box" type devices are built, to amplify the signal before the pot. In the three wire system the Peavey pre-amp does this for you.

Some of the electronic pedals have a pre-amp inside to help with this problem.

As for where to put your effects, there are three places.

1. before the vol pedal.

2. after the pedal, or after the preamp, but before the equalization control.

3. after the equalization also called effects jacks on some amps.

There are many schools of though and I am sure someone will disagree but, you usually place any time changing devise after the tone controls, such as reverb and delay. Such that you don't EQ the reverb sound. So a Lexicon will go after the EQ.

Reverb has mostly mid frequencies. If you add bass to your Equalization and then run the reverb through that, it does not sound natural and the echo is boomy, or if you add highs it can have that Ice pick edge.

Any amplitude changing device such a tremolo, etc can go ahead of the EQ controls.

Placing the delay or reverb before the volume pedal causes the "room tone" which is the reverb or delay sound to vanish when the volume is cut off. This vanishing room tone is disturbing to some people as listeners are used to hearing the echo in a room die away gradually, not just vanish.

Signal level wise, pedals are designed to operate at pickup signal level and effects units are designed to operate at line level. In other words they need a pre-amp.

You as the player have to be very careful of signal levels into and out of pedals and effects. The Lexicon has a clip light keep the input gain on the pre-amp and the Lexicon so that light does not light.

Then adjust the output level to feed your power amp enough signal to achieve the room volume you want without distortion. It is possible to run a pedal in an effects loop. But the levels are very critical to adjust. A good rule of thumb is to turn the master amp gain kind of high and keep the pre-amp and effects gain as low as possible or just below any clip light that may be installed.

I hope this helps and if you already knew this, sorry for repeating it.

I use the three wire system on my Peavey Session 2000 and it works very well, even with an electronic pedal. I use an Alumitone pickup and the only thing you hear is the digitizing noise from built in effects.

If I use the Nasville 112. There is no noise you can hear with out turning everything up and putting you ear to the speaker.

Marvin that was a great post - thanks
