Combo amps provide convenience and versatility, combining the amplifier and speaker into a single unit. However, there may come a time when you desire the flexibility of using your combo amp as an amplifier head, allowing you to connect it to a separate speaker cabinet. Converting a combo amp into an amp head opens up new possibilities for tone shaping, power options, and stage setups. In this article, we will guide you through the process of converting a combo amp into an amp head, unlocking a world of sonic potential.
Note: It’s important to mention that not all combo amps can be easily converted into amp heads. The feasibility of conversion depends on the internal design, wiring, and available connections of your specific combo amp. It is advisable to consult the manufacturer’s documentation or seek professional assistance if you are unsure about the conversion process for your particular model.
Step 1: Assess Your Combo Amp Before proceeding with the conversion, thoroughly examine your combo amp and its construction. Look for any removable panels or access points on the rear or underside of the unit. Check if there are any available speaker output jacks or other connectors that may allow you to disconnect the internal speaker.
Step 2: Disconnect the Internal Speaker If your combo amp has a dedicated speaker output jack or a connector that allows you to disconnect the internal speaker, follow these steps to disconnect it:
- Power Off and Unplug: Before making any connections or modifications, turn off the combo amp and unplug it from the power source for safety.
- Locate the Speaker Connection: Identify the connection point where the internal speaker is connected to the amplifier circuitry. It may be a jack, plug, or wire connection.
- Disconnect the Speaker: Carefully remove the connection by gently pulling the plug or disconnecting the wires, depending on the type of connection used. Take note of the specific wires or plugs you remove to ensure proper reconnection if needed in the future.
Step 3: Prepare for External Speaker Connection To use your newly converted amp head with a separate speaker cabinet, you need to prepare for the external speaker connection:
- Speaker Output Options: Check if your combo amp offers a dedicated speaker output jack or connectors for an external speaker. Some combo amps may have an extension speaker output or a line out that can be used for this purpose.
- Speaker Cable: Obtain a suitable speaker cable with the appropriate connectors for your amp head and the speaker cabinet you plan to use. Ensure the cable is of sufficient length and of high quality to maintain signal integrity.
Step 4: Connect the Amp Head to the Speaker Cabinet Now it’s time to connect your converted amp head to the speaker cabinet:
- Power Off and Unplug: Before making any connections, ensure the amp head and the speaker cabinet are turned off, and both are disconnected from their power sources.
- Identify the Speaker Output: Locate the speaker output on your converted amp head. It may be labeled “Speaker Out” or “Speaker Output.” Ensure you use the appropriate output that matches the impedance requirements of your speaker cabinet.
- Connect the Speaker Cable: Take one end of the speaker cable and plug it into the speaker output jack on the amp head. Ensure a secure connection by firmly pushing the connector into the jack.
- Connect to the Speaker Cabinet: Take the other end of the speaker cable and connect it to the input jack on the speaker cabinet. Again, ensure a secure connection by firmly pushing the connector into the jack.
Step 5: Test and Adjust With the amp head connected to the speaker cabinet, power on both units and test the sound output. Gradually increase the volume to ensure that the signal is being properly transmitted to the speaker cabinet. Monitor for any unusual noises, pops, or distortion, and adjust the settings as needed.
Important Considerations:
- Safety First: Always ensure the combo amp and speaker cabinet are powered off and unplugged when making connections or modifications to avoid the risk of electrical shock.
- Compatibility and Impedance: Ensure that the amp head and the speaker cabinet are compatible in terms of impedance requirements. Mismatching impedance can result in poor sound quality or damage to the equipment. Consult the manufacturer’s guidelines for impedance matching information.
- Manufacturer’s Documentation: Consult the manufacturer’s documentation for your specific combo amp model to understand any unique requirements or limitations regarding conversion.
- Professional Assistance: If you are unsure about the conversion process or lack experience in modifying electronic equipment, seek professional assistance from a qualified technician.
Conclusion: Converting a combo amp into an amp head offers the opportunity to explore new tonal possibilities and stage setups. By disconnecting the internal speaker and connecting the amp head to a separate speaker cabinet, you can unlock greater flexibility and customization. Remember to assess the feasibility of conversion for your specific combo amp model, follow safety precautions, and consult manufacturer guidelines or seek professional assistance when needed. With proper conversion and connection, you can maximize the potential of your combo amp, transforming it into an amp head that opens up a whole new world of sonic exploration and amplification possibilities.
