Jad & Freer Audio Sisma
After many years spent building custom amps, SISMA is the first official bass amp release by Jad Freer Audio.
Vintage meets modern: SISMA aims to combine the qualities of a classic tube preamp with the punchy and detailed sound reproduction of a big transistor power section maintaining a portability prerogative, until now, only of class D technology.
Despite its small footprint SISMA is not based on a class D power section, but actually shares the same transistor technology of our CODA power amp, delivering big and authoritative sounds capable to shake the bigger stages without any efforts and headroom to spare.
Build and hand-assembled one by one in Italy, the preamp is based on the iconic B15 sound, modded to our taste.
The tube preamp circuit is fed @ 200v by a proprietary switching power supply capable to deliver high amounts of current, much faster than a traditional transformer-based one. Same technology is used in our proprietary Class G high-performance power-amp module, reducing weight and dimensions a lot with no sound compromise.
The result is the big, open and musical sound of a tube amp with much more responsiveness ad detailed sound reproduction and, of course, a lot more headroom. All this in a small fraction of traditional weight and dimensions, overall making this amp a real game-changer in today’s market offer.Tube preamp based on the iconic B15 sound, studio grade D.I. and Fx Loop, proprietary transistor analog class G power section with high quality switching power supply.
