The Peavey VB-2™ all-tube bass amplifier is your one stop spot for fantastic bass tone, no matter what musical styles you play. The versatile preamp can give you tones ranging from squeaky clean hi-fi to vintage dub to aggressive metal. The VB-2™ utilizes a special, 3-band EQ that gives you the best of passive and active bass tone controls.
Front Panel 3 1 2 4 6 7 5 1 10 8 9 High Gain Input Input for passive basses. Tip: If you have an aggressive playing style and you use a passive bass, you may find that the LOW GAIN input will offer more clean headroom. 2 Low Gain Input Input for active basses, attenuated 6dB. 3 Mute/Tune Switch Mutes the output of the DI, the effects loop, and the output of the amp, but still allows you to use the TUNER jack on the rear of the amp.
Front Panel 12 13 11 11 17 14 15 16 18 19 High Control Active EQ control that cuts or boosts high frequencies. 12 Send Jack Output signal from the preamp that may be used to drive effects or a slave amplifier. 13 Return Jack Essentially, the input of the power amp that may serve as an input for effects or to drive the power amp as a slave amplifier from another preamp. 14 Master Volume Control Controls the power amplifier drive.
Rear Panel 20 22 21 24 23 20 26 25 IEC Power Port Your AC line cord plugs here. This is the standard IEC power connector. An AC main cord having the appropriate AC plug and rating for the intended operating voltage is included in the carton. U.S. Domestic AC Mains Cord The mains cord supplied with the unit is a heavy-duty, three conductor type with a conventional 120VAC plug with ground pin. It should be connected to an independent circuit capable of continuously supporting at least 15 amps.
Rear Panel 19 27 28 29 23 Impedance Select Switch The IMPEDANCE SELECT switch is located on the rear of the unit. There are output transformer taps for 2Ω, 4Ω and 8Ω (Ω=ohm) loads since they are the most common impedance requirements bass players run into. Using the correct setting is important for longer tube life and maximum performance. It's best if this switch is configured while the amp is on standby. Simply move the selector to the correct impedance setting.

VB-2™ Functional Block Diagram
Tube Replacement Warning! Never use ANY power tube type other than EL34s or 6CA7s. Doing otherwise may result in damage to the amp, unpredictable performance and electric shock. Use or specify a matched sextet of EL34 or 6CA7 tubes. Have the bias set by a professional. This must be done every time ANY of the power tubes are replaced. If the bias is set wrong, the amp will not put out maximum power, the output will be more distorted, and the tubes may not last as long.
