hi; I searched the forum but did not find an actual thread describing how to add an effects loop to a K200 head. I did find a reference from back around yr 2000 talking about someone getting advice on how to do it, but just found the one paragraph.
has anyone added an effects loop to a Kustom head? Can someone talk me through how to do it or send me to a web link or a ???
thanks, jack

Well depending on the head you have in regards to how many channels it has number one, and number two how many you use as in free channels, you could do this.
Pull the send signal off of the RCA jack on the rear in regards to the K200b model and pump it back into another channel from the out of your out board effects.
This RCA jack will output up to 3 volts and should be more than enough signal if your out board effects has guitar input level gain on hand.

If you could use that other channel than all you would be doing is to take the send signal you need off of the RCA jack, and then sending then effects output signal back into that channel.
There is another way to get this done but you need to make a mod to the amps 703 board and to tell you what to do I need to know what type of effects you will use in this loop?

One big thing to keep in mind with these amps made before the metal face ones is the fact that much over 1 volt of input signal will pop the first transistor in the preamp section.
To be safe on this ,whatever the loudness is set to on the amp straight in, is the max volume should be giving from a preamp boost pedal being kicked on.
So for clean backing volume levels you will just back down on the volume from the guitar itself!

If you turn down channel 1 then there is no signal at the RCA jack to send to the FX pedal.
While anything is possible, you have to ask how practical it is to do it.

One thing you can try is this.
The two blue wires that enter the left side of the pc703 board mounted on the rear wall of the amp are the audio outputs of each channel / preamp.
If you unsolder the blue wire from your good channel, extend it and place a 1/4" jack on it and a ground connection you can than feed your effect pedals.
If you than do the same thing / adding a wire and 1/4" jack to where you unsoldered the blue wire than that will be the effect return cable.
The only question I have is if your effect pedals will load down the preamp out signal too much.
If it works out for you than you can drill the chassis and install a tip, ring, sleeve 1/4" female jack on the back of the amp and than make up one cable from a 3 conductor mic cable to have both the send and return wires in that same cable.
