Cicognani Pompeii PE603 Four Head Sonic Echo

POMPEII PE603 is an echo unit that aims to revive the emotions of the past but in a smaller pedal and with improved sonic performance. Tonewise the PE603 provides from classic slap-back to up to 740mS delay. The swell mode creates a reverberation and is made possible through the use of all the heads simultaneously. Both wet & dry signal pass through a 12AU7 tube for the warmest sound with maximum transparency. A Fet cascade circuit is employed to mix gains and buffer the signal.

Thanks to great signal dynamics the POMPEII PE603 can either be used in front of the amp or in the FX loop at instrument or line level without making any adjustments.


A great deal of time was spent developing the feedback and tone circuits; as a result, the interaction between the feedback and tone controls can create the most beautiful of sounds. To fully re-create the original magic, the POMPEII PE603 is a “multi-head” echo, sharing the same first twelve switch positions as the early machines.

The SELECTOR allow you to choose the echo mode:
• ECHO: Classic 60’s “slapback echo”. One single repeat from the selected head (no feedback available)
• REP: Normal echo mode with selectable heads in feedback combinations;
• SWELL: The typical Old Italian reverb effect made with the use of all the heads simultaneously.

SWITCH has the task of choosing the heads and their combinations. The combinations are exactly the first 12 positions of the vintage PE603.

MAGIC OF AGE: This simulates the mechanical aging of the glorious Old Italian Echo. Is a particular modulation that acts on the echo delay.

LENGTH OF SWELL and TONE: use the feedback control to create the tridimensional carpet of sound.

The TONE control is strictly connected to the feedback and its task is to change the tonality of the oscillations.

VOLUME ECHO: Is the parallel mix of the effect. It can be adjusted from 0% to 50% of the 50% dry signal. This analog mixer has been completely redesigned to keep pure performance in all conditions of use. (The Volume Echo does not work in the “wet-out” socket).
