The reason I'm asking is that there's a Sisma in my area for $1400 including the case. They are new at around $1800.

If it's in your area, maybe you can try it? That extra "thing" @kirkplunkett and @carsonchilders are talking about, it's not easy to translate into words - but if you can "feel" it, you'll know.

I'm in trouble. Anyone need a P bass :)

Maybe you shouldn't go and try it, after all. :roflmao:

Yes to all above. I've had my Sisma for over a year now and no looking back. Love this amp so much. It has been on every gig in so many venues and has never disappointed. $1400 is a great price to snag it at. Enjoy!

I've noticed that the way I'm using Sisma's EQ have evolved: after discovering Volta, I was starting to think about a more minimalist EQ with just a bass and treble knobs. I've forced myself to ignore Sisma's mid controls and only use the bass and treble knobs. It works great, it sounds perfect 99% of the time - and I'm saving time. Now I'm using the mid EQ rarely, only if I want to remove a specific frequency (when there's something annoying in the room)… So now I consider the Mid EQ as a "just in case" toolbox if you see what I mean.

Do other Sisma owners have the same experience?

This has been my approach as well. I tend to only turn knobs if I HAVE to. I like a flat amp, but will make adjustments as needed for each room. I’ve only ever needed to adjust treble/bass. Once I discovered the mid frequencies that worked for my playing, they haven’t changed much from room to room.

Too polite and easily swallowed by the rest of the band are both VERY accurate in my experience with the Demeter. The Sisma freaking slays at any volume I’ve tested her at.

It's kind of funny because I've had the opposite experience with their bass channel stip/preamp situations. I wonder if they balance each other out.

I'm the opposite. The console-y mid control paired with a capable big sounding amp is the biggest highlight for me. Maybe one day they'll make a Volta with the Sisma EQ because that's my favorite part. 😊

Folks around me know that I am still obsessed with the Noble preamp. So for room translation, my amplifier setup needs a good amount of mid control. Especially if I am using in ears (and taking the signal off the noble), the EQ controls help me get the amp closer to how the bass sounds in my ears. If my amp volume has to stay low and is more of a monitor, I will boost the bass information and dump the highs so it rumbles my gut. If I am able to use a loud amp (and in ears) I am working to get my tone to translate.

I don't believe that the weak link is the preamp, but rather the power amp section and then only pushed hard.

Any of the Demeter preamps used with an adequate QSC power amp (or similar) with good speakers (especially, a Bergantino HT322) and a good bass guitar (especially, a StingRay 5), will cut through for sure.

After spending much time with my Capo, I'm very interested in the Sisma and Volta. My current and first tube amp is the Super Bassman 300 with a 410, I love the richness I get tonally but the thought of gigging with this thing does not sound appealing, just too damn heavy. I love the compact form factor of the Sisma and even the Volta, 29-30 pounds is pretty light for an all tube head.

Hoping to snag one of them in the near future along with one of JF's cabs. Not sure which, I'm leaning toward the Venere line for a more neutral response but some of the samples I've heard of the Minerva cabs sound wonderful. Jad Freer makes some amazing gear.

I also love my capo, but I’m trying to understand how they relate to each other. the Sisma is not just a powered capo right? It’s hard to find documentation online to clarify, but my understanding is that the sisma is specifically based off a B15 sound. So if you like the sound of a B15 then the sisma would be a good choice to try, but the inverse would be true. The capo does English vs America styles but I’m not sure what that’s based off of. I’d love to try one for sure, but 1600E is a big roll of the dice for me at the moment.

Does anyone here know what kind of tube the Sisma uses for its preamp? I'm taking mine on the road in a week and want to have a few for backup just in case!

12AX7. I would strongly suggest you pull the top off the amp (LOTS of screws!) and see how easy it is for you to remove and replace the tube. I tried and decided that there is barely enough room around the tube to grab it comfortably, especially as it is all glass, essentially.

I replaced mine without any issues. Replaced it with gold lion tube and saw a very minor improvement in noise level.
