Booster

The Titan PreAmp Sweetener is tweaked to my taste and meant to be used with preamp pedals or in the FX loop of your amp that unfortunately doesn't have Presence and Depth controls. While this isn't true Presence control like your 5150, it's an emulation that brings additional character and life to your tone by simulating power amp dampening.

The Zig Zag is a dual stage overdrive.

The Zola is a high headroom clean boost with a linear, transparent response. An internal voltage multiplier converts 9V internally up to 30V for unparalleled headroom.
