My Tindie shop is currently on pause

In April 2026, Tindie was sold by Siemens/Supplyframe to a new owner — EETree LLC — whose identity remained anonymous for weeks. The transition was poorly handled: the platform went offline for nearly two weeks with no prior warning, and sellers were left unable to view or fulfill orders, or withdraw their funds. The site is back online, but seller payments are still not working, and many questions remain unanswered. I don’t feel comfortable taking orders there until the situation is resolved.

In the meantime, my shop at shop.davidhaillant.com is open if you’d like to order something.

I’ll reopen my Tindie shop once I’m confident it’s reliable again. Thank you for your understanding.

It is a very simple module, easy to build, understand, and maintain, yet fun to play and musically accurate.

This very simple module is extremely useful when you need to reduce the amplitude of a signal that would be too strong for another module, or when sending a Eurorack-level voltage to a more sensitive, non-Eurorack audio equipment.
