The 258t is a fantastic, affordable workhorse oscillator for anyone building a Eurorack. It delivers a surprisingly musical and versatile sound, especially if you’re after a gritty, analog vibe and don't need every possible waveshape. It's a great starting point for a new modular or a solid addition to an existing system.

Frequently Asked Questions

The DCO-X offers far more waveshapes and features, but the 258t provides a warmer, more raw, and characterful sound at a significantly lower price point.
Absolutely, the fine-tuning control allows for easy sub-octave operation, and the bipolar CV input allows for complex modulation.
It can be used subtly, but the attenuation is crucial; the FM range is relatively wide and needs careful adjustment to avoid harshness.
