How to install the best guitar effect. The Artec QDD2 and a demo of the Active Onboard Effects Processor. Instruction on how to install it and the pros and cons of how it works. Ive skipped a fair bit of the installation but you should be able to follow the wiring and placement on your own guitar easily enough. This onboard Active Guitar Circuit runs on a 9v battery hidden in the back of the guitar. The battery should last 3000 hours? A cheap and easy way to get your own guitar booster built in.
