A good studio tool

By Fuzzball

from Ida, MI

Comments about Middle Atlantic VTB-1 Tube Blend Mic Preamp:

Unlike a ART DPS I liked this preamp on vocal tracks. I found this mic preamp to be a solid all around project studio tool. I did not find the preamp to be anything spectacular for any particular application but if you need a good all around preamp this may work for you. The preamp does provide a significant mount of noise free amplification but it did not seem to really make anything seem warm. It is not a good mic preamp if you like a clear transparent sound. On the bright side I found that the preamp did not seem to muddy up a mix after adding more than 12 tracks making this a handy tool to have in the studio.

Nice mic-preamp for the money

By Smitty265

from North Yarmouth, ME

Comments about Middle Atlantic VTB-1 Tube Blend Mic Preamp:

I needed a good, all-around mic preamp for my project studio and I'm pretty limited on budget. The Studio Projects VTB-1 has fit the bill perfectly. It works well for tracking vocals and the tube blend adds a nice warmth. It also works reasonably well as a DI box. These are my two main studio needs for a preamp and this does the job nicely. It can provide a really clean, crisp sound if you turn the tube blend knob all the way down and dialing from 0 - 50% tube blend adds in a nice warmth. That describes, from my perspective, the effective range of the product, from clean and crisp to moderately warm. It's a versatile and well-made piece of studio gear for a great price.

An amazing product for the price

By Bryce Stejskal

from Auburn, CA

Comments about Middle Atlantic VTB-1 Tube Blend Mic Preamp:

I mainly purchased this product for the tube blend feature, looking to warm up my guitar sound using the amplifier that I already own and am very happy with. When I first plugged in, I was not too impressed with that particular feature, although the preamp did do everything it is ment to do flawlessly with no noise until the gain was above 3/4. Having done a little research, I found that I should leave the unit powered on for a few days to let the tube "burn in". After doing so all I can say is wow! The amount of warmth added to the sound is worth every penny. And that is with the stock tube! However, due to the starved plate design of the tube section, changing the tube shouldn't have a very big of an impact on sound, but after reading around on the net it seems that a number of people have had very good results doing so anyways so I plan on trying that very soon. A few people even changed out the op-amps inside with great results as well! Excellent product.
