Stained Glass Audio
The Delta Bravo is an overdrive preamp that has two different frequency range boosts with two separate gain settings.
The control layout is simple, yet effective.
There are two toggles and one knob. The knob controls the overall output level. The first toggle (CLIP/RIP) controls GAIN and the second (SPANK/STANK) controls the frequency range that is boosted. SPANK is more of a "bright" setting while STANK is "dark" and fat.
