【New】JHS Pedals Overdrive Preamp. This pedal is based on the early DOD250 preamp "Gray Box," famous for being used by Yngwie and others. JHS's President Josh (familiar from YouTube videos) owns two of the earliest units (#75 and a non-serial number), and this JHS version of the Overdrive Preamp is a faithful and user-friendly recreation of those. A slide switch allows you to select between two types of diode clipping: germanium (#75) or silicon (non-serial). This is a parallel import, so it does not come with a domestic warranty. If you're okay with that, what do you think? Of course, it's new. It's a parallel import directly from the US. The box may show some damage due to being a parallel import. (The contents are not affected.) 【Reference】 This is the product site of JHS Japan: https://jhspedals.jp/guitar-pedals/3585 *JHS-ODPRE
