yes it has a fetron......I will have to give you the numbers when I get home but something like T1007 or something like that rings a bell (like I said I will post the exact number when I get home, it is written there in Black Sharpie which is normal for all the labeling underneath the old boogies....I actually still have the fetron which is rare as I understand....right now I have a 12ax7 in place of the Fetron as you can swap back and forth. There is a switch underneath that you toggle back and forth depending whether you have the fetron or the 12ax7 in there. I get more gain out of the fetron.

thanks jeff!

i know your into the mesa amps, do you know, was Jerry's Mark 1 the later model that used the Fetron also?

Yes Waldo, from what I understand the later Mark 1's were the first to use the Fetron's ....The Mark 2a's and some 2B's were the last to use the Fetron.... so as you can surmise the Fetron was a pretty short lived experiment. In fact the way they sold the amps back then with the Fetron's is that they shipped the amps with the Fetron installed but also included a nylon clip screwed on the inside of the cabinet that held a 12ax7 as a replacement choice for the Fetron. If you ever see an amp for sale that still has that clip to hold the spare 12ax7 you know you are getting an amp that most likely has been taken care of! Mine didnt have the clip but had the Fetron. It was only around for a few years.

As far as if Jerry's Mark 1 (and by that I take it you mean the Mesas he played in 75-76 before returning to the Twin in Oct 76) I would say that no it did not have a Fetron. I think the Fetron started sometime in 1977. You never know though. They always got their gear off the production lines faster than everyone else!

And to add one more edit :smile: ........ The 1980 amp definitely had the Fetron. And from the sound of that Winter 80 tour I think he chose to use it over the 12ax7......

I love this topic. Listening to Dicks Picks 32 (Alpine Valley, East Troy , 8/7/82) and I would love the tone from this China Cat.

My favorite tone is from Rosebud. Best example is "Birdsong" from "Without A Net". Jerry's Melodies with the clean tone is absolutely beautiful; And the flute sound from the midi with his choices of melodies is just breathtaking. He sounds just like a seasoned Flutist.

I really like Jerrys tiger tone 6/16/82 JGB at music mountain w Bill K on drums
Also 9/17/82 Portland ME was a phenomenally well played show with perfect balance and variety
And check out Samson and Terrapin 10/17/83 lake placid NY for killer distortion tone!

Dicks pick 18. 1978. Wolf with single coils I believe?n have to check? Sizzling tone. Almost as if a preamp tube is about to fail?

I have to say my second favorite tone is that fat humbcker tone of 1971.

Absolutely beautiful tones. Don't know if it is the best tone, but it is my favorite.
