MXR Carbon Copy Analog Delay Wet Mod

As I was designing my new pedal board, I wanted to take advantage of the Time factor and Modfactor Eventide pedal’s stereo outputs and also use the MXR Carbon Copy Analog delay pedal for a slight slap back. So, I decided to split the guitar signal into four after it left the dirt pedals with a G Lab LMS-1. With four signals,  the dry signal goes directly to the RJM mini mixer and each of the three modulation effects now runs parallel signals to each pedal input. Because the “dry” signal exists at the mixer, it becomes necessary to kill the dry signal in the three modulation effects. For the Eventide pedals, this is easy. Just make a selection in the Bypass system menu and the Dry signal is gone (Killdry option). However, for the MXR Carbon Copy, this required modification of the circuit board to remove the dry signal. I invited my good friend Randy Meador to help me so I could take pictures of how we did it:

According to MXR tech support, in order to remove the dry signal, you merely need to remove R48 (R is short for Resistor). This is conveniently located on the bottom  circuit board.

1: Remove the circuit board completely from the box. Or, if you feel savvy leave it in, its up to you. Randy and I removed it for ease sake.

Remove knobs and nuts

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2:  R48 is labeled and located here:

3: Next, solder out R48. We had our Solder gun temp about 35 as to not burn the board:

Solder carefully, the MXR is actually a "sandwich" board, with a second board on the other side

 

 

 

 

 

 

 

 

 

 

4: The Size of R48:

Sorry for the blurry shot, its SO small

 

 

 

 

 

 

 

 

 

 

 

 

5: With the mod now finished, the Mix knob now becomes the volume knob.

All Finished!

    No reason other than they sell them in three packs and are pretty cheap, plus on the tele, the nickel has that snap sound. I still use the GHS 9.5 on the strat.

    ah, I use GHS boomers usually. cuz they seem to last forever and still sound great for a long time. and that means I don’t have to buy as often cuz I’m broke! ha. yeah, for the longest time when I was young I wondered what “slinky” was supposed to mean…then you own a tele…
