If you like authentic spring reverb, you can't get much better than the super-compact Orion analog spring reverb by Spaceman Effects. Although there are actual dual springs encased in the Orion, there's no unwanted splash sound from stomping or the beat of kick drums. Four control knobs give you the power to dial in surf-rock tones or give your sound some mellower spring vibes: Dwell, Tone, Blend, and Volume. With the Tone knob, sweep between brighter and darker reverbs, and the Blend knob gives you control over the dry-to-wet ratio. It's hard to get a smaller true analog spring 'verb than the Spaceman Effects Orion Reverb.
