pritchard had a couple. One was a plexi I saw it it had a crack across the plexiglass. He said something different at the time. He talked about higher voltage like Kolbe mods. He didnt say Jackson when I spoke to him. Anyways whats the benefits of the gain stage after the tone stack. anyone know. I like the gain of the rocca but I like the feel of the cathode following tone stack ..

Hey guys,

I own one of Dave Prichards modded Lee Jackson heads. It's a late 79 JMP 100 watt. It was originally tan and he painted
the head black. If you would like any info or pictures of the head let me know. You can email me directly if you like.

I did this over 10 years ago and only can remember was that I didn't care for the mid rotary selector. Takes you into God awful territory. I liked it best with a patch cord in the loop giving a touch more. Personally I didn't care for it as there are way better 3 stage mods which are much more simple.
