Fender Twin Reverb II Amplifier Specification

The Fender Twin Reverb II Amplifier, a prominent model from the early 1980s, is a tube-driven guitar amplifier known for its robust sound and versatility. Engineered as part of the Rivera-era Fender amplifiers, it brings a distinctive tonal quality and a range of features tailored for professional musicians. At its core, the Twin Reverb II boasts an all-tube design, featuring four 6L6 power tubes and a trio of 12AX7 preamp tubes, delivering an output of 105 watts RMS. This power output is channeled through two 12-inch speakers, traditionally Fender's choice for achieving a full-bodied, resonant sound.

The amplifier's control panel is comprehensive, offering an array of tone-shaping options. It includes individual gain and volume controls for each channel, enhancing its flexibility for live performances. The channels are distinct, with the clean channel revered for its clarity and the drive channel providing a rich, saturating overdrive. Additionally, there is a three-band EQ for precise tonal adjustments and a presence control to fine-tune high frequencies. The reverb effect, a hallmark of the Twin Reverb series, is lush and expansive, adding depth to the sound.

A noteworthy feature of the Twin Reverb II is the inclusion of a footswitch, enabling seamless channel switching and reverb activation. This amplifier also incorporates a series effects loop, allowing for the integration of external effects with minimal signal degradation. With a durable construction typical of Fender's reliable craftsmanship, the Twin Reverb II is designed to withstand the rigors of extensive use while providing superior sound quality. Its classic Fender aesthetics, combined with its powerful and dynamic performance, make the Twin Reverb II a sought-after amplifier for professional musicians seeking a versatile and enduring piece of equipment.

Fender Twin Reverb II Amplifier F.A.Q.

How do I properly set up the Fender Twin Reverb II for the first time?

To set up your Fender Twin Reverb II, first ensure that the amplifier is turned off and the volume controls are set to zero. Connect the amplifier to a power source, and then plug in your instrument using a high-quality cable. Finally, turn on the amplifier and gradually increase the volume to your desired level.

What is the recommended procedure for biasing the tubes on a Fender Twin Reverb II?

Biasing the tubes requires adjusting the control grid voltage to ensure optimal performance. It's recommended to have a qualified technician perform this task to avoid damage. If you are experienced, use a bias probe to measure the idle current of the power tubes and adjust the bias pot accordingly.

What are common causes of excessive noise or hum in the Twin Reverb II and how can I fix them?

Excessive noise or hum can be caused by a variety of issues such as poor grounding, faulty cables, or worn tubes. Check all connections and cables for integrity, ensure proper grounding, and consider replacing tubes if they are old or malfunctioning.

How can I clean and maintain the exterior of my Fender Twin Reverb II?

To clean the exterior, use a soft, dry cloth to wipe off dust and debris. For tougher grime, a damp cloth with mild soap can be used, but avoid getting moisture into the electronic components. Regular cleaning helps maintain the amp's appearance and longevity.

What are the best settings for achieving a classic Fender clean sound on the Twin Reverb II?

For a classic Fender clean sound, set the treble to around 6-7, the bass to 4-5, and keep the reverb at a moderate level. Adjust the mid-range to taste, typically around 5, and ensure the gain is low to avoid distortion.

What should I do if my Twin Reverb II is not powering on?

If the amp is not powering on, first check the power cable and outlet. Ensure the power switch is in the 'on' position. If the problem persists, inspect the internal fuses and replace them if necessary. If you are not comfortable doing this, consult a professional technician.

How often should I replace the tubes in my Fender Twin Reverb II?

Tube replacement frequency depends on usage, but generally, power tubes should be replaced every 1-2 years, while preamp tubes can last longer. Signs that tubes need replacing include loss of tone quality, noise, or reduced output.

Can I use effects pedals with the Twin Reverb II, and if so, how should I connect them?

Yes, you can use effects pedals with the Twin Reverb II. Connect your guitar to the input of the first pedal, then connect the output of the last pedal to the amplifier's input. For best results, experiment with pedal order to achieve the desired sound.

How do I troubleshoot reverb issues on my Twin Reverb II amplifier?

If the reverb is not working, check the reverb cables and tank for loose connections. Ensure that the reverb control is turned up. If the problem persists, the reverb driver or recovery circuit may need servicing. Consider consulting a technician.

What precautions should I take when transporting my Fender Twin Reverb II?

When transporting the amp, ensure it is securely fastened to prevent movement. Use a padded cover or case to protect it from bumps and scratches. Avoid exposing the amplifier to extreme temperatures or humidity during transport.
