Strymon OB-1 Compressor, an oldie but goodie, the first Strymon pedal I ever bought. OB-1 combines studio quality, beautifully transparent analog optical compression with a Clean Boost with EQ curves designed to super-charge your favorite amp and reveal its true character. Featuring an all-analog signal path with premium components throughout, a high-impedance input, and very low noise circuitry, OB-1 is perfect for the number one spot in your signal chain. It’s the missing piece you’ve been searching for. on guitar or basically any instrument for tightening up levels and adding sustain. Compare my price with those listed on Reverb! $135.00
