Rare analog Echo pedal effectfrom the Roland side society Amdek. Similar to Boss dm2 sharing some common chips, but the Dmk100 has differences and some extras.

PEDAL (weight: 2 Kg)
Originally came in DIY kit (the "delay machine kit" or retail version - main panel features 4 knobs, a switch tab for selecting input impedance and a peak diode.

Back panel terminal connectors:
- jack input

Power supply there are 2 different versions:

SOUND analog generation based on Bucket brigade chips BBD MN3005 + MN3101.
Other interesting internal chip I spotted is JRC4558D (operational amplifier first version) famous the be present on early Ibanez tubescreamer.
