Don’t like our products? Too costly? Buy a Knifonium instead. Only $18,500. (Oops, nevermind, they discontinued it in 2024.) The Korg “Volca Nubass” doesn’t count because putting one or two tubes in a synthesizer (for distortion) doesn’t make it a “tube synthesizer”. There are companies making (mostly Eurorack) tube modules, like Trogotronic, Bard, Zerosum and a few others. They tend to be very different from our products. You will just have to buy them to see what they are like. (We design most of Zerosum’s circuits for them, but take extra pains to make them totally unlike ours.)
