STAGE (Unicord) EC-100 tape echo

[timrichter9]

Hey all-

I am totally befuddled by tape echos. Here's what I got:

Stage branded Unicord EC-100 echo with two heads and original Apollon tape

Problem:

I can still hear remnants of old recorded guitar through playback (even when sound on sound knob is in)

Is this a head problem, tape problem?

Any help is appreciated.

Record and erase use a bias oscillator. A weak bias signal can result in weak recordings and poor erasures.

Erase head could be open or connections broken.

If erase/record head is not well aligned with the playback head, the playback will pick up edges of erased tracks.
