Axon AX 100 MK II – Clean Signal Mod

Do you own the Axon AX 100 MK II? Weird noises when passing the normal guitar signal through it? Not any longer, if you know how to operate a soldering tool.

The Axon was a great MIDI controller, the Axon in 2013 still is a great MIDI controller. It is not made anymore, Axon was bought by Terratec and they stopped building this device some time ago. Released in summer 2013 is the successor of the Axon: the Fishman TriplePlay. When used to the Axon 100 then it won’t take you long to discover that the developer of the Fishman device is actually the one who also developed the Axon. TriplePlay is a cool device. But it wouldn’t implicitly replace the Axon. For those who still own and use one here a mod to finally get rid of the noise that is added on to the normal guitar signal that should just be passed through the device without touching it.

And this is exactly what we are going to do – to not have the Axon touch our guitar signal. We will do a straight bypass operation.

It’s fairly simple. You should use a shielded cable, even though it would also work with just two wires. Open the Axon, unscrew the circuit board and take it out of its housing and follow the pictures for each step.

Locate the input and output area
Locate the input and output area
Remove L4, L17, L38 to open up the signal path

Solder the two wires as shown to the output area
Solder the two wires as shown to the output area
Solder the two wires of the other end of the cable as shown to the input area
Solder the two wires of the other end of the cable as shown to the input area
Final result should look somehow like this

When connecting your guitar now the magnetic pickup signal from the guitar will fully bypass the Axon’s circuit board and hence not add any annoying sounds to it. It should bring up new life again for this great device. It is such a cool MIDI converter. It is fast, endless configuration possibilities. And I find it looks pretty cool. Actually, I’ve never used the sounds from the red circuit board, the so-called Wave Table card. Always used it to produce MIDI notes that then trigger synthesisers in hardware or software on the computer.

P.S. let me know if I should do the mod for you. Contact me using the contact form below. You will need to send your Axon to Germany or Switzerland.
