OAM VB-2+

The VB-2+ will take you anywhere from a clean boost, light overdrive, distortion, to full on doom. You have complete control over the two transistor stages, with volume and bias controls for each one. You can run one stage hot into the other for the most distorted/compressed sound, or you can run the first one low and the last one wide open for the most clean/dynamic sound. The bias controls can be turned up past the point of sanity to create spitty, ripping effects. It may squeal at you if the settings are too intense, or cut out completely if the input is too low and the bias too high, but it makes finding the right balance totally in your hands.
