I have been using this in my recording studio, but I am listing it for a limited time to secure funds for new equipment. It has never been taken out of the studio and has been used in a rack since purchase, so there are no major scratches, but there are some minor scratches and dirt. Also, there is some crackling in the switches, but it was not a problem once the settings were decided. Regarding the modifications: Capacitors and transistors in the amplifier cards have been replaced. Transistors include vintage selected parts, including Motorola. Vintage parts equivalent to original NEVE, such as the BA283 equivalent preamp card, have been selected and implemented. The output transformer has been replaced with one tuned based on Carnhill. It also features functions such as a VB filter and a VARIABLE AGE SWITCH (which simulates aging by controlling capacitor capacity). Basically, no claims or returns will be accepted except for cases where the power does not turn on. I am also listing this on another site. Please understand that the price may be lower here due to fees, etc.
