Avalon Design VT-737SP Reviews

5 years and still a beauty

I know that the Avalon 737 has been around for quite some time now, but it is still Number one for me. yesterday somebody tried to offer me something else, something new and we did an A/B head to head compare session, and the 737 stood out by miles... If you're a good sound engineer, you'll know how to tame this wild horse. The pre-amp and EQ sections are out of this world. Colored ? Maybe, but I just love this colour

Great tube pre, EQ and Compressor

This preamp sounds great for multiple recording applications- I own two 737s, they're versatile and quite powerful when you understand all the functions.

Great Processor

Ive been used to record guitar, acoustic guitar, bass, vocals in my studio and the sound its always great, warm and fat in all situations. I really like to have a Tube Preamp with EQ and Compressor, I can setup the whole tone using this avalon.

I use it with vocals an acoustic guitars, usually with a Neumann TLM49 or Rode NTK.I love the warmth of the tubes in the preamp. The eq is outstanding. The compressor section is very nice, but a little tricky because the attack and release times are a little bit slow and tends to sound too transparent. I compress a lot the vocals and bass and I really like the sound of the optical compressors. If you are good sound engineer an musician, Youll love it.

Biggest piece of junk on the market!

I've had 2 of these. The first one I bought brand new. I was planning on using it on bass but the compressor was so limp is the best way to put it. It is so sqooshy and all over the place. I does not accurately compress. Because of this overwhealming issue and consumer complaints they started ffering a higher end commprssor mod if you wanna pay another $500 plus!!! So this just shows that the original compressor is faulty and does not effectively do it job! However I did buy a second unit with the compressor mod in it and it worked 50% better!!! The problem is... every pro studio hs to have one! For some reson people do request them quite often. I will let the client think they are playing thru the unit (have it lit upand meters moving from sending a CD Player to it or something. Lol. But actually I will have them going thru a Neve or API into a distressor. Also, the mic pres way to colorful. I like high end transparent mic pres that actually capture the sound of the instrument, not add sound.The EQ's are decent but who records with EQ anyway? No one... ammatures! EQ is for live applictions so maybe this might be a good hunk of metal for the stage but int the studio forget it!

This will accept 100v to 240v, 50-60Hz (selectable). You will need the proper adapter for the cable, but you will not need a power converter.
