When I went on my cruise, I met Randy Rhoads brother Kelle and Sister Kathy.  They have a show that they do called Randy Rhoads remembered to celebrate his life. All of the guitarists, everyone from Bumblefoot to Mike Orlando on the cruise do Randy Rhoads songs.  Enjoy!!!!

Randy Rhoads Remembered
I went on a cruise called Axes and Anchors.  I met everyone from Bumblefoot to Marty Freidman to Zakk Wylde.  Here is the link for the Seminars for Marty Freidman, Zakk Wylde and Yngwie Malmsteen.

How to Dumble MOD a Fender Black Face

Alexander "Howard" Dumble has revolutionized the world. He started out in California with a small amp shop where he specialized in modding Fender amps.  One of his most popular mods is the Ultra Phoix mod.  In my search for the illusive Schematic and secret information surrounding the mod, I came across this article "Cool Mod for the Normal Channel"   You can read up on it at the following link.  Cool Mod for the normal channel

As I am not a amp builder, (but someday hope to be) I recruited my friend John Dandry to assist me.  He is an amazing amp builder located in New Orleans. We used my 1964 Fender Princeton as the donor amp.  We used Push Pull switches instead of the regular switches in case we did not like the results. This mod is truly amazing. I have never heard a Fender Princeton sound so good.

This is the work that was done.

1. Replaced: 2x 100k plate resistors in preamp and  all Electrolytic caps in amp.
2. Removed fixed 27k bias resistor with 10k pot and 22k resistor for adj. bias
3. Added Shielded cable at input to lower noise.
4. Mods: Cool Mod : Rock/Jazz and boost pull knobs on treble and bass.
5. Rock/ Jazz - tone filter Boost - tone stack bypass Local feedback on gain stage Mid control
Thank you to the following:
1. I want to thank Dumble for his creativity and intuition 
2. I want to thank Steve Aloha for writing such an amazing document on the Cool Mod.
3. I want to thank my friend John Dandry for his amazing skill and workmanship.

Here is a Video of the final result before putting the chassis back into the Cabinet.  This is only the amp with no effects.

How to build an Effect order Switcher

How to build an Effect order Switcher.

I was looking through the forums  at  http://guitar-fx-layouts.42897.x6.nabble.com/808-and-zen-td18075.html#a18242 and saw this today.  It is an Effect Order Switcher using a 4PDT Switch.
This is very useful when switching between effects.
