VD400 : good delay unit - 300ms max, has a sonic character.

its functional, and sounds fine.

not the best or sweetest sounding feedback resonance but it does sound raw in its way.

its good value - a very cheap price delay with a reasonable sound.

warning : 300ms maximum is not a very wide range of delay time.

be sure you this is what you are accepting.

for example - if youre playing a slow reggae song guitar riff, the repeat rate may not go as slow as you hope for. its a limitation of this unit, although its stil useable at faster rates. its is good, for what its cloning.

it clones original "bucket brigade" curcuit designs that maxed out at 300ms,

build quality fine , dials feel fine,

sound is fine, price is a joke.

its not the highest grade audio equipment, but an amauter or a pro can stil use this, and people will just say "sounds cool"
