Here we have a new module by Analogue Systems. With a long history of building analog and digital delay, reverb and chorus effects Analogue Systems now created a module that blends easily between echo and reverb sounds – the RS-650 is now available!
RS-650 is an echo/reverb module based on the two Analogue Systems classics RS-310 and RS-440 – it can be used as a delay or reverb, with delay times from 70 mb to 200 ms and 2.5 ms to 150 ms in reverb mode. The circuit is based on a bucket brigade device with six parallel delay tabs with different levels and delay times. The summation of the six tabs creates the dense reverb. Due to the traditional design of the circuit, the clock frequency in the delay is audible in the output signal. Therefore it is recommended to use a lowpass filter after the RS-650 to reduce the clock noise.
All in all the RS 650 brings a great vintage bucket brigade sound to the table. If you want it to, the RS 650 can strongly color the sound that you feed it with, here is a video to give you an idea about its sound.
