POD X3 Tones are not directly compatible with the POD HD500. However you could use POD X3 tones as a reference point to start with on the POD HD500, as long as the same amp model is used between the two.

If you are looking for tones I would suggest that you check out our CustomTone website for all our user created and uploaded tones available at:

In addition you can post a request for this tone in our "Share your Settings" forum at the link below:

Another thing to keep in mind when trying to create your own tones:

If you want to create an artist-inspired tone “from scratch,” start by researching the guitar setup you are trying to emulate. Web sites, such as guitargeek.com and uberproaudio.com, list the rigs of many well-known guitarists. Guitar and recording magazines often print accurate diagrams and layouts (sometimes with the actual microphones used and distance from the cabinet).

Finding the following information will help you create an artist tone from scratch:

Amplifier, speaker and cabinet. Generally speaking, open-back guitar cabinets (such as a 2x12 cabinet found on many Fender® and Vox® amplifiers) will have less low-end response than a closed-back cabinet (such as a 4x12 closed-back cabinet used with many Marshall® and Mesa/Boogie® amplifiers)

Guitar (make/model) and pickup type. Alder or Ash bodies (commonly found on many Fender® guitars) sound different than mahogany bodies with maple tops (commonly found on many Gibson® guitars). Single-coil pickups (often used for bright/clean tones) sound different than humbuckers (which sound darker than single-coil pickups but not as noisy when used for higher gain tones)

Pedals, effects and signal-chain placement. Effects can drastically change a guitar tone so you should know what effects were used and where they were placed (between the instrument and amplifier, or after the amplifier).

Microphone type and placement. If possible, find out the kind of microphone used to record the tone and its angle and distance from the speaker. All of these play a significant role in changing the sound.
