The Contender borrows special features from its big brother, the all-tube Defender 3/4 guitar amplifier from Kustom. Using a high-voltage 12AX7 tube preamp design, The Contender harkens back to the small tube guitar amps of yesterday: chock full of sweet tone and snarling attitude.The Contender combo amp is housed in a '60s-era pine speaker cabinet, a key ingredient in its lively tone. Controls provided are Volume, Bass, Treble and Master, as well as Bright and Master Volume Bypass switches. With the Master engaged, it's easy to get chubnky overdriven tones that ring with clarity. With the Master Bypass swithc engaged, the amp is pure old-school, eliminating the Master Volume circuit entirely. Speaker duties are handles with authority by an 8-inch Eminience speaker.Special details include an exclusive stitched-pattern covering, an oversized, cushy leather handle, plywood baffle, jewel light and vintage-style power switch. Tube Tone lives inside The Contender.
