SISMA Bass Head Review: A Tale of Tone and First Impressions
Upon receiving the SISMA bass head, my initial anticipation was met with a slight delay in delivery, extending closer to six weeks rather than the initially expected four or five. While not a significant issue, it would have been appreciated to receive communication regarding the delay without having to initiate it myself. Nonetheless, let's delve into the experience with a positive perspective.
Motivated by a referral from fellow enthusiasts on TB (TalkBass), I was drawn to SISMA's promise of delivering the elusive tone I had been seeking, particularly in a lightweight format that eluded other options, such as valve tones in pedals.
Opting to support a smaller boutique business, I harbored expectations of a personalized touch in the unboxing experience. However, the reality fell short as the packaging lacked finesse, with styrofoam smudges marring the bag and a conspicuous absence of an owner's manual or warranty information. It's moments like these that offer an opportunity for boutique businesses to shine by infusing the unboxing with a sense of purpose and gratitude, perhaps through a simple note expressing appreciation for the support and how you have contributed to their mission. Instead the experience was more like receiving a used bass amp off EBAY or Reverb. Not a game changer but for 1700 euros surely they could make more effort (warranty/link to manual or include the manual? or a note as to where to quickly find the manual?)
Despite these initial hiccups, the true test awaited in the sound and build quality. And here, SISMA impresses. The bass head exudes a remarkable, tube-like tone that immediately commands attention. Its sturdy construction, though a tad weighty, instills confidence, fitting snugly into an over-the-shoulder gig bag.
Exploring its features, I found the headphone jack to be functional, albeit not surpassing expectations compared to other amps. Similarly, the DI Out proved its worth, delivering the promised tonal richness directly into my recording setup. Others may prefer a DI that has pre and post controls, this does not.
However, not all aspects garnered equal praise. The presence of three fans, particularly the intermittently loud ones flanking the unit, detracted from the otherwise immersive experience. Additionally, the lack of preemptive communication about this feature in may deter prospective buyers. As I type the head is turned on, and all you can hear is these two fans turning on and off.. on and off.. Is it going to blow up? I have owned a lot of gear and this is a first for me.
As I continue to explore the nuances of this bass head, my present assessment stands at a crossroads. While the undeniable allure of its tone beckons, the shortcomings in unboxing, fan noise, and lack of response on their return policies when I have asked, temper my enthusiasm. (I know what the website says but there are always other hoops to jump through).
In conclusion, while the SISMA bass head holds promise, my verdict remains uncertain, warranting further consideration for prospective buyers.
Overall Rating: 3.5/5
Pros:
- Superb tone reminiscent of tube amplifiers
- Robust build quality
- Functional headphone jack and DI Out
Cons:
- Lackluster unboxing experience
- Intermittently loud fans detract from immersion
- Overpriced: This head would be better priced at £900.
- No modern features such as usb c connections etc you get in newer amps. ( I knew this in advance but its worth pointing out to those who are used to more modern builds)
I will update this review as I learn and experience more during my two weeks of testing it out at home.
Finally, cab demos 
Very solid feeling. Nice.
