"The reverb used is external, it's not coming from the Midibox Sid"
via this auction
"Midibox SID DIY synthesizer. It was built by my friend at Feedback Modules 12 years ago. It has a solid metal case and works perfectly. It's the real deal when it comes to C64 sounds. It has some gritty 8bit sounds as well as a real analogue multimode filter, 3 oscillators and plenty of modulations. The chip came from my old C64, it's the latest version, the one with the fewer bugs. I've made a video demo with some presets, you can find it on this page. The reverb is coming from an external unit."
