Nice inexpensive Pre October 7, 2017
Reviewer: MTDrummer from Springfield, MA United States  
This pre works well for the price point.  Does not excel at anything per say but is solid across the board.  A better power supply would be nice.

Studio Projects VTB-1 March 18, 2012
Reviewer: Ben from Medford Lakes, NJ United States  
I decided to purchase a VTB-1 after reading and hearing really good reviews. I put it against my Presonus MP20 and there was no comparison, the studio projects was much better. The mp20 sounded thin and brittle, maybe that is why it was discontinued.  Although, I don't know how it compares to the new Presonus stuff.  At the time the unit was $99, but at $149 it is still worth it.  If you're getting your first preamp, I believe you would be happy. If I use the tube setting, I generally like it about 12:00, especially for flute.

Good basic clean cheap September 9, 2011
Reviewer: Anonymous Person from La Jolla, CA United States  
The VTB-1 is a great way to get a quality signal if your other gear's preamps are subpar.  I used two of these when I had a Roland VS1680 which had noisy, grainy preamps. With the tube blend off the VTB1 gives a good, quiet signal. I never had any use for the tube blend, but just as a basic clean preamp or DI this is a very good value.

This was my 1st outboard Pre... September 3, 2010
Reviewer: Jason Dickerson from Tustin, CA United States  
& it it did what it was supposed to do. With the "Tube Blend" knob all the way over on Solid State it gives a tone that sounds way better than $150! The Tube Blend is an OK little bell or whistle, I never found myself using the tube side very often though. I have a lot more pricier preamps/channel strips now but I still go back to the old VTB-1 from time to time just because I know what I'm going to get out of it when I put something into it... Darn good DI too. Thanks for the eye time.

Excellent value for the price! June 23, 2010
Reviewer: John S. Trageser from Murfreesboro, TN United States  
I've used my first VTB-1 enough that I thought it warranted having a pair. It's not going to give you $1,000-per-channel price bracket performance, but it's got some good character and excellent versatility.

Run it as an insert, run it as a DI, feed it mic or line-level signals, even set it up dirty with high input gain and moderated output gain - it'll be happy.

With tube-blend at full, I had good results on male baritone with an Oktava 319. I've also liked most basses through it, both miced and after a DI (haven't used the Hi-Z input often, but it hasn't given me any trouble).

Did have a problem trying to rack my pair (see review of the VTB1-RK), but can't complain.
