If you would like to return your unit to the original presets, please perform a factory reset (see the Lowdown trouble shooting section). Q: Are there any video tutorials I can view to learn more about the Lowdown? A: Please see the Lowdown Movies in the product description page. Q: Is there an editing software that works with the Lowdown amplifier? A: No, there is editing software for the Lowdown series as there is no way to connect the lowdown amplifier to your computer. Q: Is there a "manual mode" so I can avoid the presets and just use the knobs on the amplifier? A: Yes, one you have selected your preset you want to run in manual mode, hit the preset again and the light will turn off, indicating you are in manual mode. Q: How do I change the tuner's reference frequency on the Lowdown? A: The Lowdown Tuner Reference Frequency cannot be changed - it's 440 all the way. Setup/Connections Q: Is there a direct out on the Lowdown 400/750 HD series amplifiers? A: Yes, there are balanced line level XLR outputs on the on the Lowdown 400/750 HD series. The line level XLR output is not affected by the output volume of the amplifier, and will send a cabinet simulated tone to your mixing console. Q: What if I do not want the cabinet tone but rather a unaffected tone (like a DI Box?) A: If you desire an unaffected bass tone, the Lowdown 400/750 HD series does have a quarter inch preamp output to send an unaffected tone to a mixer. Q: Can I use a Line 6 controller Lowdown 400/750 HD? A: Yes, we recommend using the FBV Shortboard with the Lowdown series. The FBV will work with the Lowdown series (although there will be numerous buttons that have no effect), and the FBV Express will not scroll through the banks.

Q: Are the XLR outputs of the LD series line level? A: Yes, the XLR outputs on all of our Lowdown amps are balanced line level outputs. The line level output not affected by the output volume of the amplifier, and will send a cabinet simulated tone to your mixing console. Q: What if I do not want the cabinet tone but rather a unaffected tone (like a DI Box?) A: If you desire an unaffected bass tone in addition to the cabinet simulated tone you will want to go into a DI box and send the DI signal to the mixing console, and have the instrument output of the DI go into the instrument input of the Lowdown amplifier. Q: What controllers work with the Lowdown series? A:The FBV series is the correct controller for the Lowdown series, we recommend the FBV Shortboard or FBV Express. The FBV (Longboard) is not optimized for use with the Lowdown family of amplifiers, and the FBV2 is not compatible with a certain amount of early LowDowns.

Line 6 Amp Trouble Shooting Q: I am noticing hiss in the headphones with the Lowdown Studio 110? A: This may not be an issue on all Lowdown Studio 110 amplifiers. Depending on what brand of headphones you are using, as well as what amp model/settings are up, you may or may not hear hiss. Individual preference will determine if the perceived signal/noise ratio is acceptable. Please DO NOT return your Lowdown Studio 110 for a replacement unit if you feel that this is an issue. Our service centers would be happy to fix this issue for you. Keep in mind; this fix requires that one of our technicians perform a custom modification to the headphone amplifier, which requires that we open up your amp. The reason that some users may hear hiss is due to the gain structure design of this amp and a couple of surface mount resisters need to be replaced. Customer Support is unable to guide you through the repair and only our authorized service centers can take care of this fix. NOTE: If a customer opens up their amp and attempts to alter their electronics in any way, they will void your manufacturer’s warranty on their Lowdown Studio 110. Also, keep in mind that the repair may take several weeks based on the specific service center’s turn around time. If the nearest service center is too far from your location, and you need to ship your unit to that service center, Line 6 WILL NOT cover the associated shipping costs If you are aware of the above information and you still wish to have your amp repaired, Line 6 will cover the costs of parts and labor. Please have your receipt ready before you contact a service center. If you cannot find your receipt, please talk to the dealer where the amp was purchased, and request a duplicate receipt.
