In my effort to continually improve the recordings you hear from Tesco Productions I have added several microphone pre-amp upgrades. A variety of units have been acquired – even though multiple units are from Presonus who base their designs foremost around a Class A circuit. Among the Presonus pre-amps are two Eureka channel strips which provides extensive eq, compression, multiple input impedence selection (which greatly helps match the pre-amp to instruments and mics, as well changing the contour of the recorded sound) and tube emulation if desired. Also from Presonus I now have two Blue-tube units – both the original and updated version 2. These units have a tube in them which can be dialed into the audio path in varying amounts as desired. The other piece purchased is the HHB Classic 80 multi-stage tube pre which adds another dimension for available sounds. Our initial listening has been favorable overall and I know we’ll fine tune the best applications for each of these pre-amps in recording sessions to come. Keep your ears peeled!
