Pompeii PE603, thanks to its great signal dynamics, 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.
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.
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.
