Suggestions on best free reverb plug-in?

SIR 1 is a great free convolution reverb - see www.knufinke.de/sir/sir1.html you need to add impulses for it to work, and http://freeverb3.sourceforge.net/ has links to some, as well as the freeverb download and info on other reverbs out there...

I'll second Mark's suggestion. Before I had Perfect Space, SIR was my go-to reverb when I wanted something lush and long. It's a convolution reverb, meaning it interprets impulse-response (IR) files, of which there are a great many available on the net for free. Get the right IR file, and SIR can sound like just about any reverb you want it to sound like.

Like all convolution reverbs, though, SIR is a fairly heavy load on the CPU, so you probably won't want more than one - maybe two - instances per project.

Of course, if you spring for Producer Edition instead of Home, you'll get both the Sonitus reverb and Perfect Space, both for "free" (as in bundled). Between those two you'd definitely be set for reverb.

I like Ambience from Magnus. While it's technically not free (Shareware), you can use it forever in Demo mode.

Another interesting plugin of this sort, not fully reverb, but a mixture of verb, phaser, and delay is Wollo Spacer. You'll get close to your John Lennon effects with this one.

Finally, the Lexicon Pantheon that ships with Sonar Producer is a very good convolution verb.

If you want to pay for a verb, take a look at the More Feedback Machine from uHe (the guy that does Zebra). For any effects that uses delay and/or verb, this is the one, and then some. Pricing is not prohibitive.

Other good commercial verbs that I like, though most require dongles -- IK Classic Studio Reverb, WizooVerb, Oxford Sonnox Verb (bundled with compressors & EQ), Waves RVerb (Renaissance), TrueVerb (basic Waves sets).

There are sources around to discover what reverbs John was using on those albums. Also, you might check out the abbey road effects and see what's up there, though these are quite expensive!

+1 for Ambience, very flexible reverb with a lot of good presets.

At the moment, you can download the Rev-1 Pro reverb for free. Check it out at kvraudio.com.

PSP Audioware makes a free Springverb spring reverb plugin, not the world's most flexible reverb but useful.

A lot of what you hear on John Lennon's voice on some of his best known pieces is actually slapback delay, not reverb. So if you don't have a decent delay plugin, you might want to think about that. Sound on Sound had a very good article a couple of months ago on using reverbs and delays, take a look for it.

I must not get out much... I think the indigenous cake plugs are pretty decent.

SIR is good.

Glaceverb is good, it has a unique sound that is not readily do-able with other reverb plugins.

Haven't tried ambience.

Ya i found the Glaceverb the other day. Looks pretty cool. I also downloaded SIR, beings that is the reverb ive heard the most people suggest. I downloaded a few others also that seem interesting. All in all, thanks for all the advice guys! Oh and its not that i was saying that Sonar's reverbs suck or anything. As a matter a fact, it seems everyone on here with PE seems to hold the Reverbs it comes with in high regards. Its just that I havent actually bought Sonar yet, so i was just going off what i had heard from a friend. I plan to buy Sonar sometime within my next few checks. I seriously think it is hands down the most awsome PC DAW available. Im just currently deciding between the new Studio 8 or the new Home Studio 7.

Jeroen Breebart (the man behind tape sim Ferox) has a really good free reverb called omnizone http://www.jeroenbreebaart.com/audio_vst.htm

Bootsy is about to release a new reverb soon but you can check out sound exsamples while you wait http://rekkerd.org/bootsy-announces-epicverb/
