New Fortin Meshuggah??

If fortin was making them, the price would be ok. But yeah. When tiny hands doing the job, combined with the customer service you get when you have a faulty product from him..
Ceriatone has tiny hands making stuff and is nice and takes care of customers for a lot less

It seems like Fortin announced Meshuggah mk2. I think Hermansson modded Marshall for Thordendal is a lot better. What do you guys think??

A serious question for you all:
Do you really like the sound, playability and response of this amp?
If so, I'll double my prices once I start taking orders again in late summer or fall of this year :cool:

I have the original and many others. It really is something different. Like it or not.

Not saying it's worth $6k.
 
I'm still waiting for the $8K MK2 version of the Evil Pumpkin to get released...

What most people refer to as the "Jose Mod" in it's most basic form, is a pre-tone stack master volume control with some clipping diodes. This mod also utilizes a cap and a resistor between the cathode follower and volume control. So really... you have one resistor, one cap, one pot, and two zener diodes (or transistors) between V2b and the tone stack. About $8 in parts. The degree of clipping can be changed by using different zener diodes and you can wire them up symmetrically or asymmetrically for different clipping characteristics.

You can get creative and add multiple clipping options on a switch, alter the value of the cap to affect the sound/feel, add resistors in certain places to lessen the effect of the diodes and make them more "tube-like" in their response, and so on. All of this is outlined in books on the tube amps.

Now, that basic mod sounds much better when combined with other things in the circuit. Like utilizing independent gain controls for each of the first two stages, raising V1a plate resistor value slightly, adding a bright cap to one of the gains, biasing each stage to sound like how you want via cathode resistor and cathode bypass cap combinations, and playing with the value of the first two coupling caps. Anything goes. All depends on what kind of sound you want.

And the classic "Jose" amp itself had other things like dual/switchable masters.

Taking it further, you can then play with the bright cap value; NFB circuit; presence cap values; depth cap values; slope resistor values; grid resistor values; PI cap and resistor values; power stage grid resistor values; power section for voltage changes; and so on. All of this stuff is outlined in great detail on many DIY forums and in many books on tube amp design.

Can you recommend said books for those of us that want to learn more about this stuff ?

The Ultimate Tone, by Kevin O'Connor is a good starting point. There are 11 books in the series. Don't necessarily need to read all 11 when just starting out. Each one is about a different set of principles and topics relating to tube amp design so you can pick and choose.

Especially for beginners I'd recommend the TUBE AMP WORKBOOK by Dave Funk - old but good

Then a while later after you've generated some knowledge & experience continue with:

Designing Tube Preamps for Guitar and Bass by Merlin Blencrowe
and
Guitar Amplifier Preamps by Richard Kuehnel

And... don't miss Randall Aiken's huge knowledge here: http://www.aikenamps.com./index.php/tech-info

Btw. Randall Aiken and Merlin Blencrowe are my personally highest regarded masterminds concerning tube amps.
Even I would take my hat off to both of them out of respect considering their vast knowledge 🤠

Hermansson blows this thing away. No contest. Hermansson has established himself as a rare talent.
 
maybe a hermansson stage 4 meshuggah head - seems a logical next step/evolution. wrote per h. about it [for my #9 script] - we'll see =\
it may only do one thing, but it does that one thing very well.
hermansson is to fortin now, what car bomb is to meshuggah - next evo kind of stuff i guess =\

have stock '82 4104 [headshelled] that [with the right tube suite] is balls-out nasty. bought it new / dallas in '82 / $600. still have the marshall shipping carton that i used for a coffee/side table until i could rent furniture. meat & potatoes kinda stuff =\
