Strymon OB1 compressor & boost guitar effect

Strymon OB1

There is a monster trapped inside your low or medium gain amp, and OB.1 can set it free. Bring out your amp’s character in ways you never thought possible. Hear things you never knew your amp could do.
OB.1 provides greater than 20dB of gain-compensated compression, and with the integrated Clean Boost, an extra 10dB of full-frequency, mid or treble boost is available. Use the mid or treble boost together with a bit of transparent compression, and your amp will sound like it was just modified by a world-class boutique amp designer.
