Got SID ?

If you already own a SID chip, please use the discount code “chip” for a 25euro discount

We’d be more than happy to test and install any SID chips that you can source. Just drop us an email.

Note about 6581 chips: They do have a fair amount of distortion especially at low cutoff values, this is a sound I personally love but some might prefer the more modern 6582/8550 version of the SID which is brighter (but more background noise) . I currently don’t have 6582/8550 in stock. Feel free to use the “chip” discount if you prefer to source your own. I’d be happy to install and test it for you prior to shipping.

I want the second SID chip!

We have a very limited supply of SIDs and are trying to save one for everybody on the waiting list.
don’t feel like you only have half a therapSid without the second chip. It is fully functional with one

You can mix and match SID types and the removable panel makes it easy to set up.
