Feature:
The sound is the main feature. There are trim pots inside but I didn't see any need to touch them. There is a dry out, in which case the dry signal is muted from the (now 100%) wet out. That lets you mix the wet in with the dry later, or split them to different amps or speakers. The wet is dark on this delay, leading some people to freak out about how stereo mode is dark, not at all, it's just the echoes that are dark...durr...

Quality:
They last from the fact they are still in use after 20 years.

Value:
You can get digital things like Line6 DL4 that claims it can do this but this is the real analog bucket brigade delay and nothing has quite its glow or smear. Plus there's no degradation of the original signal that I can hear (whereas going through AD/DA conversion will).

Desirability:
I love it, won't part with it, but haven't heard the higher-end Maxon units.

Sound:
Dark, creamy, dreamy, perfecto. Blends beautifully. I'm not sure you want anything else really, other than say a Fulltone TTE or a Space Echo. Digital delays are for weeners.

Ease of Use:
three knobs twist and shout!

Support:
haven't contacted them

Overall:
Simple, does what it's supposed to, knobs can be twisted by foot if desired. Dial in your tone and go, no fussing with ten different buttons and modes. Easier to dial in that recall what preset you want. And the TONE!

Feature:
This Delay is esay to hook up to your Instrument. Nothing difficult about it.

Quality:
Nothing to say here except....AWESOME!!

Value:
The price is not bad either!

Desirability:
"I Want IT" just for the sounds that you can get from it!

Sound:
This has toi be one of the best IF NOT the best Analog Delay Units on the market today. I have heard several Pedal Steel Guitarists use this Delay and I absolutly love the sound that comes from one of these units. I just had to get one! I thinks that these Delays units are AWESOME!!

Ease of Use:
Different Delay sounds from this unit are easy to obtain...Just turn the knobs until you find what sounds best to fit your style.

Support:
I haven't had a problem...yet as I have just ordered this unit. BUT from whoat I hear from other people that do have this Delay unit, I do not anticipate any problems with it.
