The Soloman is basically three bass overdrive pedals in one. A three way selector switch allows you to choose between a "warm" overdrive which replicates the subtle and warm overdrive of an old school tube amp, a "bright" overdrive for richer, crisper, more punky picked tones and "normal" which is a nice mix of both worlds.....warm and round sounding with a slightly fizzy edge! This three way control is complimented by the usual level and drive controls to adjust output and filth! Where there is Joyo, there is joy! This pedal is specially designed for Bass.
