Tube Microphone preamp.
The least expensive preamp that we have available (and probably ever will offer). We honestly couldn't beleive the performance this little preamp gave us... While no Avalon 737, this little VTB-1 is a great little solution for someone looking to get into a step above their sound card or mixers preamps, or someone who simply needs a decent phantom power preamp solution for a condenser mic.
The new Studio Projects VTB-1 is the ultimate in low cost mic preamplifier technology. Incorporating true class A/B switching, the VTB-1 is a totally discrete circuit. Unique to the VTB-1 is the "Tube Drive". The Tube Drive is a variable drive to a 12AX7, that allows the user to blend as little, or as much of the Tube Drive they want. This VTB-1 allows the user the most flexibility of any mic preamplifier in it's price class.
The VTB-1 allows you to go from a pristine solid state sound, to any combination of Tube Drive you choose...even hard distortion for guitars and bass! The VTB-1 is must have device as the perfect mic preamplifier for any microphone!
