WERSI BASS SYNTHESIZER AP-6 | Analog Synthesizer 1977 | HD DEMO 

(c) 2021 by AnalogAudio1
Lexicon MPX500 for reverb effects and Korg SDD-3000 delay were used.
The Wersi Bass Synthesizer (Model AP-6) is a weird analog monophonic synthesizer from Germany. Very uncommon controls, uncommon behaviour. You never know if it works as it should. Funny after all. You can combine waveforms with different footages. The filter is a bit of a joke (called Wah-Wah), but the synth has a nice and brave vintage tone overall. Beware, it's not exactly an acid monster... As someone in the comments said - a synth flute and lead machine :-)
