Traynor DynaBass 400H offers the best of all worlds with its combination of tube and solid-state topographies capable of delivering subtle tube warmth, full on tube drive or a pristine clean bass tone on demand.
A separate parallel tube overdrive circuit with an innovative wet / dry balance control that allows the perfect blend of overdriven signal to clean bass tone on demand. This allows as much growl or as little tube warmth as required to be encorporated into your sound while maintaining a clean central tone to maintain definition and clarity.
The five-band EQ, with a semi-parametric with sweep mid, and a continuously variable Scoopcontrol offers one of the most versatile tone stacks found on a bass amp. A switchable limiter and a compressor circuit with user definable threshold control have been added to the tube input circuit as well.
*The Scoop function sweeps from a flat frequency response to a mid-frequency dip at 300 Hz. As you increase beyond the halfway point on the control you begin to boost both the top end and bottom end to your tone, in addition to further reducing the midrange level.
The DynaBass 400H Bass head offers a front panel wet / dry control for the effects return, footswitchable tube overdrive, footswitchable effects return and a pre / post selectable XLR balanced Tube DI output. Speakon and 1/4-inch extension speaker outputs have been added for quick and easy connection to any bass cabinet.
A front panel tuner / mute switch kills the signal to the amplifier (and DI output) for silent tuning with the front panel mounted 1/4" tuner out jack.
