A awsome studio tool for any studio

By Fuzzball

from Ida, MI

Comments about Avalon VT-737sp Class A Mono Tube Channel Strip:

The Avalon VT737SP may be expensive but it is a very versatile studio tool. The unit has very usable preamps which I especially like using on acoustic guitars. The compressor is easy to use and it does a very good job (it seems to not leave many annoying artifacts). You can get everything from a gentle soft compression to a fast pumping over compressed signal (which is sometimes desired for unique applications). The de-ess control is also excellent to have, I found it very useful for a female singer that tended to over enunciate the s sound on tracks. The EQ is also very clean and smooth making this a great unit to use with many options.

Big Boy Sound In A Two Space Rack

By James Greene

from California

Comments about Avalon VT-737sp Class A Mono Tube Channel Strip:

Avalon is right on the money with this one. I use the Vt737 on just about everything. I even track stereo sources with the two that I have. I guess you could argue that there are better dedicated compressors, but the one in the Vt737 is more than adequate. The clarity is superb. For your front-end you can't go wrong with the Vt737sp. If you want to sound like the big boys you need big boy equipment.

You get what you pay for

By dale de la Fuente

Comments about Avalon VT-737sp Class A Mono Tube Channel Strip:

I was in need of a new preamp and decided to go to a local guitar center just to look at what was in stock. I had been looking at the $300 ranged mic preamps that were in stock but then started looking at the avalon 737. From $300 to this was a big jump in price, but I'm glad I made the purchase. I've had the avalon 737 for about 6 months already and absolutely love it. I've used it to track hip hop and r&b vocals, but I've also used it on sax, drums, flute, clarinet, trumpet, and low brass. All I can say is that everything that was tracked using the avalon was amazingly smooth, clear, and crisp. My recordings have dramatically improved in presence and sound quality from years past with this single piece of equipment. It is well worth the price. It is built like a tank and holds the resell value very well in case you ever need to sell it later on. I would definitely recommend this.

    I have spent a lot of money in the past to arrive at the point of picking up one of these preamps. I think you get what you pay for in a lot of gear. Save your money and time searching for other preamps to match the quality you get from the 737. Get you one!
