Originally posted by devastone View PostIt's more than just the number of pins, the pins have to be the same too, there are dual opamps in 8 pin packages that are not pin for pin compatible. FWIW, I'm 99% sure there is a SIL version of the 4558 which is a dual opamp, but the opamp the original used was a single opamp, a Toshiba TA7136P. Years ago we did a side by side with a friend's MIJ DS-1 and my MIT DS-1 with the SEM, the MIJ was warmer and smoother, but if you are using it as a boost, either would work fine, in face the SEM version is a great boost for a crunchy amp. They aren't totally different, but it is noticeable, especially if you are cranking the distortion on the DS-1 and running into a clean amp.

FWIW, I don't think the DS-1 ever used LEDs for clipping, but the SEM used one to create asymmetrical clipping with one of the silicon diodes IIRC. The original DS-1s were very different, they used a chip that went I think went OOP, so they changed the circuit to use the standard JRC44558 (and similar) opamps.
FWIW, the original chips are still available, but they they aren't compatible with the current circuit so you can't just drop them in. The BYOC Orange Distortion is the original circuit, so if you want the MIJ DS-1 tone, that is the one to get.

I wanted to add that of course I've been using this stomp more and getting familiar with it.
Hard to really pin what upper mid freqs this thing slathers on but I'd guesstimate 3-6K, maybe even a lil 8K... really adds that "glassy metal crunch".

If you're not in the know about the DS-1, you're probably asking yourself, "Why on earth would I buy a kit to build a DS-1 clone when I could mosey on into any Guitar Center, and pick up a real one for $35?" The DS-1 currently in production is not the same as the original DS-1 that was produced in the 80's. Now you're

Still - cool vid. I'll keep this in mind for my Riot vid...

Here is the comparison vid (DS-1, Ultra Drive, Keeley SEM DS-1, CB78D):

Happy holiday boosting!

I like a nice tight scooped sound, with plenty of top end, think Amon Amarth or King Diamond.
