2 CH DR Loop Mod

Post by colemaneuclid » Wed Sep 17, 2008 6:06 pm

I have a 2 channel dual rectifier and I can't find a good picture of a pre/post mod of the loop. I want to make it a series loop. here is a pic of the backside of my DR

i hope this helps you
so remove the green wire from the left lug, and tape it up with electrical tape and tuck it away.
next, move the orange wire from the right lug to the center lug.
pretty damn easy once you get in there and realize thats all it is lol
when i did it, i set aside a large chunk of tim to do it and i was done in like 20 minutes (i was really nervous about actually modifying it and doing it wrong lol)

as you can see there is a green wire going to the mix pot on my amp as where yours it is going to the send pot [mid tab] now if i rewire my green wire from the board to the send pot would that work?

So with this mod does it render the send/mix pots useless?

well i went ahead and modded it anyways [my uncle is an electronics genius] he found the schematics and said it would work out fine. sofar so good. but it sounds way more raw when i only use a patch cable in the loop with the send pot at 100% the mix pot is taken out of the equation. with the loop bypassed the amp sounds mean and full like it should. i still have yet to tweak it with the effects loop on both orange and red.

Well I did it. I went and bought the soldering iron and looked at the pictures and watched some soldering videos on you tube and I did the FX loop mod myself. Holy sh!t!! Me Triple rectifier has come alive. I cannot believe how much better it sounds. I love it! Now I have a question or two.

1. What are you guys setting your send level at? I find that 1 to 2 oclock is good. Anything higher and I start clipping my effects.

2. When I am not playing with the volume on my guitar down I have a hum I never really had at least not as noticeable. I moved my Boss NS into the loop and problem solved. Has anyone else noticed this hum?

Hey guys I am new here and since I just got a red g-system :P I have some questions for you guys. As you know the Mesa Dual Rec's FX loop has a lot of bleed. I have a dual rec racktifier with the black chassis. I care nothing about the FX blend option or turning the fx loop on or off (I want it on all the time). It would be cool if the send knob still works. Soo all I have to do is clip the green wire? or do i ALSO need to solder the orange wire to the read lead on the pot? This is suspiciously too simple. :|
Any help is appreciated.
Thanks,
-Zak-

Clip the green wire AND solder the orange to the red. The send pot is still active, but the mix knob isn't.

The send pot will still work, but the mix knob won't. You'll also still have the master volume function and the loop can still be turned on/off with the footswitch.

You don't even have to move the orange wire really. If you don't, all that will happen is that the Mix knob will become a return level knob that doesn't go all the way down to zero - no big deal, you can either use it like that or leave it maxed, in which case there is no electrical difference compared to moving the wire.

*All* you really need to do is disconnect the green wire(s) from the pot.
