Jad Freer Sisma Mega Thread.

Sounds like words of a controlling dictator. Control the speech, control the people.

I like warranties, safety and compliance certifications, and solid service, parts, and distribution channels. Does Jad Freer Sisma have any of these in the US?

Hi,
If you had to compare Sisma with some similar and familiar head, what would that be?

That's a tough one. First off, it's not extremely different from a number of other excellent bass heads currently on the market. We have a number of truly excellent options, nowadays. I guess as I try to think of a closer comparison, I keep thinking that it's kind of a blend between a WD-800 and the traditional "GK sound," like an 800RB. A lot of the words I can use to describe it - full, clear, dynamic, fairly balanced, not overly colored, but not sterile, etc. - can apply to a number of other heads. It is quite good, though, and I think it compares nicely with any of the top bass heads on the market.
 
As well as you sir :)

The connection I was trying to make with the tube amps and the SIsma was, maybe the damping manipulatedated, like some in the Subway line to give the amp it's distinct sound.

I didn't understand your point initially and I thought you were going off topic, because the video you were citing has already caused a long off-topic sequence at the time.

Now I understand your point. In short, you were truying to guess what makes Sisma sound the way it sounds, and you thought about damping by analogy with the Subway heads you own - that was legit (sorry again), then Agedhorse replied there are too many factors etc…

I guess as long as Jad Freer don't want to share technical details or explain their design goals, it will be very difficult for anyone to imagine how Sisma sounds without truying it. I like tombowlus description, it's always difficult to describe an amp's tone, I think it's a good summary.

One of the main reasons Tom Bowlus has a test rig (Sisma, 110 and 210) is because his reviews are universally considered fair and he can also do bench tests too, the so called "facts". So I'd like to leave my "opinion" out of the discussion.

Thank you.
I know it's not easy but in writen form, like talkbas ,comparison is the only somewhat reliable way to have an idea of what we are talking about. "Descriptions" are prety much useless.
I am still looking for that "unicorn" which is able to cover all my diferent basses and still......
 
I took a chance on the Sisma and the Capo. Coming from both Mesa 800+ and WD800. Not getting rid of either of those cuz I have no reason to and I love both but I'm very pleased with both Sisma and Capo being that I was dropping lots of coin and not getting to hear/use them first. I have absolutely no regrets and Sisma has been at every gig since I received it this past November. It's now my number one amp for gigs. And I'm pretty sure JFA has a return policy if you're not satisfied.

Thank you for your kind words and your confidence! We are really looking forward to putting the Sisma and Venere cabs through our bench tests with the AP system! :thumbsup:
 
So as we are to read the review :)

Our bench testing is backed up a bit, as we had to get the AP system updated, and we are also incorporating video into the various stages of the bench testing process. This should be super cool, but to try and do things "right" (in terms of high quality video/audio) can be very time-consuming, and definitely becomes its own rabbit hole...

It might have been a language barrier. I speak Jibberish as my first language.

Hi- I’ve had the Sisma for some gigs this month and gotta say it’s the best new amp I’ve used since my old SVT days-

I’ve enjoyed the ease of light weight class D amps, and they have come a long way, but I’ve never been that happy with them. I’ve always used extra pre’s or eq’s to try to get the visceral feel of the old lead sleds but never really got there. Always missing something.

The Sisma is something else. 1st, the class G power section has the weight/slam (insert your favorite word) I’ve been missing. The notes have more integrity and cut thru the mix at any volume. Class D feels like MP3’s in comparison.

The front end is on point also. The baxandall high and low eq’s are deep and sweet like the best old tube amps, and the active mids really work to sculpt the tone or fix wacky room resonances. And the pre adds saturation very gradually so you can really dial it in.

btw, with the right cab it works with upright also.

Bottom line, what’s said on the JadFreer site is true. It’s a game changer.

I’ve been doing this for a long time, am a hard sell, and this thing is making me a believer - so I ordered one.

happy to answer questions.
Cheers all

I felt the same way. I really wish I had the need for one right now…
 
I don't understand why it's so expensive?

First, it's not more expensive than a Mesa TT800 or WD800.

Second, it's not mass produced in China, Sisma is build to order, made by hand by a small company in Italy.

A lot of innovation, technology, R&D, handcraft, and love...

I find it super affordable compared to this :D
 
I’m ready to move on from my Tonehammer 500 after about a decade.

I’m between the Sisma and Fuchs Audio’s new heads. I’m sure it’s way too early for anyone to have tried both, but IF you have, please let me know your thoughts on them. Thanks.
