Expensive - Good

I've used this review title before because I feel similarly about this pedal. This should not be the price it is but its good and effective to tour with.

Gorgeous and super drippy reverb

This is one of the best spring reverb ever made. It's super drippy and sounds awesome for blues. It's not as high fidelity as the Strymon Flint or the El Capistan but it has a vintage esque to it which is great. Most people will keep the TONE really low as it may sound really bright but it will kill the lush reverb and kills the sparkle too. I normally keep the Mixer below 9 o clock while the tone around 3 to 4 and dwell below 11. This sounds really good with blues . For more modern sounding reverb, I would use the Walrus Fathom instead. I love the simple control layout and the classic look to it. Such a bummer Boss decided to discontinue this pedal.

The best compact spring reverb pedal there is

Soundwise it captures the original Fender Springtank Unit from the 60s perfectly, I do not have the direct experience for comparison but that's what many say on the net. It takes some time to get to know the conrtols but then you can have the most authentic spring reverb sounds. The surfy bear might be a little more versatile and better in sound quality, but that thing is a pedalboard on its own. If you can grab one of these, do it. You won't need nor want another spring reverb ever again.

Best Reverb Pedal I've Ever Owned

The FRV-1 is the most realistic Fender spring reverb pedal I've ever heard/have. The COSM technology successfully recreates the spring drip whilst being a very simply pedal with a mixer knob, tone knob and dwell knob. Very good for recreating the 60s sound of many bands. It's that good I've sacrificed other kinds of effects due to having to have this and a RV-6/Holy Grail Max on my board as it's too good to take off. Not good for very long reverbs hence the other pedals, but for that authentic spring sound, it's the best you can have besides the real thing.

Very Good Pedal

Classic Fender reverbs are warm and lush, and recreating such organic tones can be a difficult one for solid-state units to pull off. Here, though, the FRV-1 twangs in spades, with everything from a subtle enhancement all the way to full-on Dick Dale madness faithfully at your boot tips; even the 'pop' caused by pick attack is recreated.

As long as you balance the tone with your dry amp signal, you'll get a huge amount from this pedal. It's a compromise but, for general gigging and recording, this is as authentic as it's likely to get.

Good Reverb pedal

The classic fender reverb in a stompbox size. As always boss provides you with a pedalboard friendly pedal.

Best Spring pedal in a small Stompbox

What can I say? It is the best spring pedal. No suck tones and is delicious!
