From the vendor
Overview
The Spirit Box is a Accutronics “Belton brick” powered reverb unit capable of light springy sounds to haunted castles full of cavernous screams. Very flexible control set allows you to dial in anything from country slapback tones to massive depth shoe gazer type reverbs.
Controls
• Attack – Controls the length of Pre-Delay
• Dwell – Adjust the length of decay (feedback is normal at extreme settings)
• Depth – Adjusts the wet/dry signal mix
Details
• Designed for a 125B enclosure with top-mounted jacks
