Omega Mod for Fender Hot Rod Deluxe

[DPM309]

Has anyone performed the "Omega Mod" on a Fender Hot Rod Deluxe? This mod is supposed to give a richer and fuller sound on the clean channel and more drive and sustain on the other channels. There is very little information on this mod, must be a proprietary thing. I did find some other information on hot rod mods on a couple of Fender forums that involve changing out components with higher quality components in the PI section and changing a couple of cap values and replacing other caps with higher quality caps such as Orange Drop. Here is one quote:

"If you're interested in trying your own solution, look into the following: change C23 to .0022uF or .0047uF, and add good quality caps of the same values for C18, C5, C6, C7, C2, C10, C24, C25, C26, and C27. Also, add a couple of lower gain tubes in V2 and V3 and your drive channels ought to both be pretty usable."

Others also mention replacing the Master Volume pot with an audio taper pot and putting a NOS 12AV7 in V2. All of these mods would be fairly inexpensive and easy to perform If anyone has any additional information or suggestions on this mod, please let me know.

Thanks,

Dan

Dear Dan.
Don't buy very much the theory that changing a lot of caps by same type and value but from "Mojo brands" affects sound much, if at all, but putting an *audio* taper pot (which should be there from Day1) instead of a hard to set Linear one, is *the* most important and audible Mod you can make in that case.
Start by doing that, it will be very useful.

I have always found that a good nos tube in V1 of any amp makes a world of difference.

I agree, especially when compared to a cheap $6.00 Chinese 12AX7 tube or an inexpensive Sovtek, found in many mass produced amps on the market!
