Universal Audio 4-710d 4 channel Tube / Solid State Microphone Preamp. Great sounding 4 channel Universal Audio Mic Preamp.Love the dynamics incorparated on each channel, its great to be able to go from solid state to tube or a blend of both voices depending on the source material. Its a fantastic workhorse mic preamp, everything Ive ran thru it sounds transparent to bold. Has some rack wear but in excellent condition fully functioning. As of now just comes with power cord. However rest assure it will be packed well. Please feel free to ask any questions. I will only sell within the continental U. _gsrx_vers_631 GS 6.9.8b6 (631).
