Тайванский DS-1 - тайванскому рознь!
Как минимум, с февраля 2008 тайванский Boss DS-1 идут с чипом JRC.
Это тот чип, который Аналогман ставит в своих модах.
Вот что о нем пишет Аналогман на своем сайте:
The DS-1/Pro mod is the same changes as the Super mod but it pulls out the stock inline chip, and replaces it with a JRC op-amp chip. This chip really improves the tone, giving it more warmth, clarity, and headroom. It's still a DS-1: more distortion, crunchier, and more low end than a tube screamer, and after the mod it sounds awesome even with the DIST knob down all the way. It is a very useful pedal with the DIST knob down for people who don't want too much distortion, or have an amp that is already distortiing. It does not have the midrange hump of a tube screamer, it actually has a scooped midrange for more of a modern sound. Most people will use them at high DIST settings, but they sound awesome at low DIST settings too. Play gently and get a clear, clean tone, play harder and the crunch and distortion comes out clear and full!
