JRC4558DD TS-808 FOR TUBE SCREAMER IBANEZ TS-7 TS-9 OD-855 BOSS SD-1 SD-808

JRC4558DD ideal and selected for the following effects pedals:

• Tube Screamer
• TS-808
• TS-9
• TS-7
• Boss SD-1
• Made by Japan Radio Corporation (JRC). This is a Higher Gain & Smoother in the Highs version of the JRC4558D (notice one has one "d" and the other two "DD" s). The JRC4558DD has a smoother gain structure with a slight rounding off in the highs. This "DD" chip sounds surprisingly good in an SD-1. This is the stock chip you'll find in most SD-1s and TS7s. This is a good match for my SD-808. Try it and I think you'll agree. My SD - 808 have utilities top end and more hair. The JRC4558DD tames the SD-808 to bit in the highs.
