Tech 21 Boost Chorus

Creation Audio Labs touts the MK.4.23 Clean Boost as the purest, most transparent clean boost pedal on Earth–and this rugged little stompbox has the sonic muscle to back that claim. You can use the MK.4.23 as a simple clean boost to push your solos above the mix or crank your tube amp up to high saturation overdrive levels. The MK.4.23 can also act as a Direct Inject (DI) box that keeps your signal fidelity together when you plug it straight into a mixer’s line input or DAW interface.

The deceptively innocuous Breakdown guitar effect pedal from Danelectro is basically a tiny six-stage gain booster that serves up everything from light, subtle dirt to smooth overdrive and further on to heavy, full-on distortion. Set the gain level with the Break-Up rotary switch and shape it further with the pedal’s Volume knob as well as your guitar’s own volume controls. This slim form stompbox doesn’t run on battery juice and needs to be connected to a compatible 9V power supply.
