I have the TC Electronic HOF.
It's a well rated verb pedal and it does have some nice verbs.
But I can't get a good spring verb from it.
Just about every spring setting sounds short and dry, nothing like a real spring verb like the one in my Fender HR DLX or the accutronics in my TubeWorks RT2100 combo.
Combining the real spring reverb of the Fender HR with the HOF results in some really cool and lush reverb.
Nice.
With the HOF I tend to use the 'plate' verb setting, and 'mod' has a really cool verb effect with some type of chorus in there.
The coolest thing about the HOF is that you can tweak a verb with the 'tone print' software on your PC and then load that new verb into the pedal.
And there are also a LOT of artist reverb creations that you can down load into the pedal, but it's limited cause there's only 1 setting so you can only import one other reverb.
If you're looking to use just 1 reverb setting, at different levels, you can try the mini HOF.
It's very compact and you can still load in a tone print reverb that you create ot tweak or import one that's already created.
For real spring reverb nothing beats a REAL spring reverb.

There's just something about the physical spring motions that interplay with the amp that a pedal just can't do.
I did recently hear the Boss Fender FDR-1 reverb pedal and that pedal is the closest to sounding like a real Fender spring reverb.
In an A/B blind test you'll question whether you really can pick out the real spring vs the pedal.
