Product Description

The Reverberation Unit Type 646 is a analogue spring reverb and overload unit. Featuring duel mechanical springs for a classic spring reverb sound, as well as an overload circuit for crunching up or warming up your sound allowing this to be a fantastic for drum processing and guitars alike. The Spring Reverb was an integral part of genres like Reggae and Dub where it was used addictively on snares and other percussion, now, it can be in your studio as well.

Key Features:

  • Fully Analogue:
    Not just a spring reverb, the overdrive circuit features rich and warm harmonic content, amazing for boosting guitars, and dirtying up drum breaks. The Duel Springs also provide that, “Twang”, we all know and love when it comes to Spring Reverbs.
  • Eurorack Friendly:
    Whilst the rear of the unit does contain 1/4" inputs and outputs, the front panel is Eurorack format friendly, fantastic for integrating into your existing modular gear and with other Behringer units such as the K2 and Kobol that share the same form factor.
  • Simple:
    There’s only 3 controls, 4 if we count the on off switch. Units don’t need to sound complicated to sound good, gain controls for both inputs and a reverb amount, you don’t need much else to sound good.
