Danelectro corned beef reverb - $35
This is an interesting little reverb petal. Rather than a traditional spring reverb, it is a quirky, warm digital-analog hybrid (PT2399-based) that operates essentially as a fixed, bucket-brigade style delay. It has a retro, lo-fi "slapback" and vintage-style depth rather than large, ambient hall reverb sounds. I'm completely changing my entire pedal board arrangement and have many other pedals listed.
