LA's Sound guru Bob Bradshaw, who developed the Custom Audio pedals, has married MXR and so its quality treasures now run under this Name. The MC-401 Custom Audio Electronics Booster is the right solution for guitarists whose amp actually already has an optimal sound but could just use a bit more gain. Overdrives and treble booster would bend the frequency response, which is not always a desirable effect. The MXR has been getting it right for years - without distorting the sound it gives the amp just the kick that it was missing; ideal for bringing out old Marshalls, Fenders and Voxes, creating a strong lead sound without bending their beloved signature sound. Adjustable from 0 to 20 d.
