There are 2 pages of module modifications currently.

Most mods can be found Here

And mods for clean (non-distortion based) modules can be found Here

I really need to try that clean mod..
My "clean" module is almost impossible to get a non distorted sound..
At least with my EMG eqipped guitars...

Ned, you should "sticky" this thread. I refer to these links all the time.

Do I understand correctly the C3 mod is the reason for the bass switch on the new Egnater dual modules?
So no need to mod these babies I guess.

I had that same issue as I use EMGs in all my guitars.
The clean mod solved everything.

So I received my Randall Brown a few days ago, then I checked to see if the resistor R1 ( 470 ohm) was changed to 150 ohms per the documented mods. Maybe I received an old module sitting on a shelf, but it has the 470 installed. Also, the bright toggle switch stopped working after 1 use. So, I think I'll change the resistor, do the cap mod, and replace the switch.
Anyone have similar problems with these Randall modules ? Is swapping out the resistor worth it, or just leave as is ?


Thanks,


H

The bright switch is not effective if you have the gain maxed out. The less you have your gain cranked the more effect the bright switch will have. Back off your gain and see if the bright switch still works

What I meant is, the switch actually will not move from off to on. I can feel a gritty resistance to move to the right. Maybe the switch was over heated during assembly, or solder made it's way into the switch contacts.
Thanks,


H

Update- Did the cap and resistor mod to the Brown. I tried the 150 ohm resistor (R1) per the documented mods, but it really destroyed the tone. I opted for a 330 ohm resistor, and .0022 (F222 Mylar film capacitor, C3). It sounds incredible now, glad I made the modifications.

Is there a listing of specification capacitor and resistor values for the modules? I think it would be nice if we could go through and QC these components on the Randall modules. It would be really useful also to have a photo or line drawing pointing out the placement of the resistors and capacitors on the PCBs with their spec values. Are any of these things available? Thanks.

Need to replace the level potentiometer on my 1086. What value/spec is this unit?

You're talking to a real electronics noob, so please be as detailed as you can.

Many thanks!
