Unmatched versatility and solid tone are ensured by the Traynor DynaBass 400s combination of tube and solid-state topographies in the signal path. Built for the player that may need to unleash a more aggressive bass tone, the DynaBass 400 offers the ability to add subtle tube warmth or full on tube drive to a 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, from 100% drive to pristine and anywhere in between. This allows as much growl or as little tube warmth as required to be incorporated into your sound while maintaining a clean central tone to maintain definition and clarity.
A switchable limiter and a compressor circuit with user definable threshold control have been added to the tube input circuit as well.
The five-band EQ, with a semi-parametric sweepable mid, and a continuously variable Scoopcontrol offers one of the most versatile tone stacks found on a bass amp.
*The Scoop function sweeps from a flat frequency response to a mid-frequency dip at 300 Hz. As you increase beyond the 1/2-way 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 400 bass combo 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 the addition of an external 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.

Bass Combos Series Overview
The first product Pete Traynor ever designed and built was an extremely reliable and affordable bass amplifier. For over forty years, musicians have chosen Traynor bass amplifiers for their great sound and unmatched durability.
Years of experience building instrument and loudspeaker cabinets has taught us that using MDF (medium density fiberboard) or particleboard for bass cabinets isnt conducive to a long rattle-free life or a great bass tone. Therefore all Traynor bass cabinets are made with a reinforced solid plywood cabinet construction to ensure unmatched reliability. A full metal grille protects the high quality custom designed speaker components used in all Traynor Bass combos.
