Frequently asked questions
Do both work with active and passive pickups?
Yes, both the AB and EXG are compatible with active and passive pickup systems.
What is the main functional difference?
The AB is a variable gain boost (up to 20dB) for volume and overdrive, while the EXG is a frequency-response tone control that boosts lows and highs while scooping midrange, similar to a guitar amp's three-band EQ.
Which is better for a tube amp player?
The AB is specifically designed for pushing tube amps into overdrive and increasing lead volume. The EXG shapes tone character but does not provide dynamic gain boost.
Can either replace a standard tone knob?
The AB replaces your tone or volume knob with a push/pull pot activation. The EXG functions as an active tone control offering more range than a passive tone knob.
