Frequently Asked Questions

It's not a traditional amplifier; it’s a custom-designed tube circuit that subtly saturates and colors the EQ's response, adding harmonic richness and perceived loudness without harshness.
Software can approximate the frequency response, but the Rubber Bands’ transformers and tube amp provide a tangible, analog 'feel' and harmonic complexity that’s hard to replicate digitally.
While the spec sheet states 20Hz-20kHz +/- 0.3dB, the transformers likely extend the usable response a bit beyond that, offering a subtle low-frequency roll-off and a smoother high-end than many other equalizers.
