Thank you to your friend and mine Jacob (employee at synthrotek), we all have a new great mod to work on for the APC. This basic and fun kit can now be adjusted to kick out deeper frequencies and bass tones. Rad for drone, melodies, etc. Gets chunky and fun. We are not carrying this as a Kit but you can HEAD OVER TO THE BOM in our “Tech” area to find out what components you are needing to replace. Let us know if you have an success or any mods of your own.
