Hodnotím 4 hvězdami proto ,že není u toho žádný návod, takže pokud chcete zjistit co to všechno umí ,musíte si to zjistit sami ,také bych uvítal kdyby byla možnost volby bufer, nebo true bypass, když máte za sebou samý krabice s bufrem, muze to být na škodu, jinak vyzkoušena japonská kvalita i když to dávají dohromady někde mezi opicaky.
