IGS Audio 572 Red Stripe – 500-Series Tube Preamp

Pure tube preamp in a 500-series module

In short

The IGS 572 Red Stripe is a mic/instrument preamp designed in the 500 standard. The module is transformer balanced on input and output using Sowter and Edcor transformers. All regulators on the front panel are stepped switches. Excellent for recording any sources, including line signals from microphones, instruments like guitars or keyboards (Hi-Z input at the front of the unit).

In detail

This is an excellent preamplifier, that can be used with a variety of sources: line signals, guitar pickups (via Hi-Z input), dynamic, condenser and ribbon microphones. It always provides outstanding results. With one knob gain control (41-stepped) you can push it nicely, but still make sure that you don’t overload the next stage of your signal chain. The second stage overloading gives some sweet harmonics vibe. Adds a lot of unique flavour. HiZ input is accessible from the front of unit. Handy!
