Used item, lowest price! Operation OK! SSL Solid State Logic Alpha VHD Pre All channels have been confirmed to be working. It has a wonderful warm sound. The mid to low frequencies are thick and very analog. It's clean with a wide frequency range, and the sound image is solid from the time of recording. The mid to low frequencies are thick. For a product where one channel costs around 50,000 yen, I believe it has a cost performance that surpasses not only products in the same price range but also those from other companies in more than double the price range. There is no crackling from the knobs. It's rare, so please consider it soon. Accessories: Genuine adapter included. We will ship quickly using recycled cardboard and bubble wrap.
