The Custom Special 90 offers the best of all worlds in a high powered all tube combo.

Capable of operating in either a 90-watt Class-AB mode for large stages or concert halls or a more manageable 20-watt pure Class-A mode for club dates and the studio, the Custom Special 90 delivers high headroom and clarity or super saturated lead & blues tones on demand.

Taking the Custom Special 90 2x12 combo on the road is a breeze with the all-new Celestion G12 Century Vintage speakers on board. Designed to deliver the classic Celestion G12 12-inch speaker tone in a lightweight neodymium magnet design, the New Century speakers allow maximum impact from a 2x12-inch combo that is actually a lighter amp that it’s 50-watt 1x12 counterpart.

Although lightweight, the Custom Special 90 2x12 combo still uses an all metal chassis and solid plywood cabinet construction, ensuring unmatched reliability over the long haul.

Maximum versatility in the clean channel is ensured by the innovative Brit / USA channel voicing switch unique to the Traynor Custom Special Series. This USA / Brit switch actually relocates the tone stack relative to the gain stages in the clean channel, allowing the Custom Special series EQ section to respond with either a crisp ‘American’ style tube amp, for clarity and definition, or with a grittier, more ‘spongy’ ‘British’ flavor associated with the great UK amps of the 60s and 70s.

An Expander circuit that first appeared on Traynor’s popular Custom Valve 80 has been included on the Custom Special 90’s rhythm channel allowing the amp to deliver an almost acoustic-like tone when required.

The Custom Special 90’s lead channel offers more flexibility and a wider tone pallet than competitive tube amps in its class. Modern and Scoop switches offer the player a choice of ‘vintage’ tube drive or a more aggressive ‘scooped’ guitar tone. A solo boost level on the lead channel offers easy access to an additional gain stage, allowing the amp to deliver a clean, crunch and lead tone from the simple two-button footswitch (included).

Accutronics spring reverb, separate parallel effects loop with send and return for external side chain effects like chorus and delays, as well as an in-line loop through for EQ’s, Compressors or other effects, a master volume, Presence and Resonance controls are all included on the Custom Special 90.

As an additional feature the Presence and Resonance can be removed from the circuit with a simple touch of a switch on the front panel, shorting the signal path and delivering a truly vintage tube sound for the tone purist.

All Tube Guitar Combos Series Overview

North American built all-tube Traynor guitar amplifier combos deliver maximum versatility and superior all tube tone. Careful attention to detail during the design stage and quality component selection during manufacturing ensures years of unmatched reliability and sonic versatility.

Traynor guitar combos are made with a solid plywood cabinet construction. We believe MDF (medium density fiberboard) or particleboard often used by other manufacturers can’t deliver great guitar tone or a long rattle-free life. Heavy gauge all-metal box chassis protect electronic components in every model.

We’re so sure of the design and our manufacturing prowess that all Traynor guitar amplifiers are covered with a two-year unlimited warranty.*

*Two-Year Unlimited Warranty valid in Canada and U.S. only.
