    Double Bass SF Tantra MAS - Why did I pay $2700 for an amp in the past when..??

    Full ICE1000ASP module specs are here: Link Removed go to the page 2. (1175W into 4Ohms @ 1% THD) Theoretically, you can drive loads even down to 2 Ohms (see page 5). And of course, the lower the load, the more power dissipated into it. So at 8 Ohms (like a single Mike's Bodai MAS110 cab) you...

    The Fan was planned and there's a place for an 80mm one, but it doesn't seem that the power amp heats up to the point of needing it. The preamp doesn't come with a fan but we can build it in at a special request. The manual does talk about the DI routing options: "The first group of mini...

    Just heard that some 2DI4 users had a great experience with this NOS EF86 replacement. One would think it should work equally well in the Tantra. The price is quite high, though: Link Removed

    To be honest with you, I never measured them. I had a bass plugged into the experimental EQ circuit on a breadboard and was fine-tuning the filter components as I was listening through my Adam A8X studio monitors. Whatever sounded the best is what I settled for. The treble and bass shelving...

    For those folks that find the harmonic generators "too subtle": 1. Make sure the gain (clean combined with overdriven) is as high up as the headroom allows, just short of triggering the overload LED at loudest notes played. 2. With the compressor switch to the left (out), turn the compression...

    Hi everyone, we are watching the first reactions to the Tantra with great interest. It would help if those early owners posted as much feedback as possible so that we can plan any future tweaks or corrections. By the way we had a lot of interested bass players check the Tantra out (with...

    399 x 275 x 90 mm A retractable side handle adds another 10mm to the width (399+10). Divide by 25.4 for inches.

    Methinks it needs a hard case with some foam padding. This one looks too light for a fairly heavy box.

    I'll post the back panel soon. Still need to get the special screws for XLR's and Speakons. And today is a holiday here in BC, no post office, no businesses open. Yes, the DI is after the tubes, including the overdrive blend, but it can also be switched to include full processing, in which...

    I appreciate the many suggestions all of you have. We'll consider everything, but also have to be aware of our more basic challenges such as small quantity parts availability, cost, serviceability, price/performance ratio, and last but not least issues plaguing small boutique companies like us...
