The Marco 8 is a true octal tube preamp. This is not an interpretation or an emulation, it’s the real deal. Inside the Marco 8 lives the actual preamp circuit from the legendary Masco ME8, with just a few minor modifications to adapt it to pedal format. Although it runs on a standard 9 V power supply, some clever electronics boost the internal voltage to over +40 V. This means you get the fat tone and rich harmonic complexity of the original tube preamp, now in a compact and convenient form. The MARCO 8 comes with a PSVANE 6SN7 tube installed — you may swap your own 6SN7 tube by opening the rear plate.
