Behringer 2600-VCO
16HP Eurorack Voltage-controlled Oscillator Module with 4 Waveforms, PWM, and Low-frequency Mode
Description
The original 2600 came out in the ’70s and was a mainly all discrete transistor design with some op-amps. The discrete circuitry gave the 2600 a very distinctive sound and were used by artists like Jean Michel Jarre, Depeche Mode, Stevie Wonder and so many more. The 2600-VCO is a compact and versatile module, giving you a VCO featuring four simultaneous waveforms with the ability to control a wide frequency band for amazing flexibility. Modular synths were a landmark development in electronic music and today, it’s about to get better.
