Frequently asked questions

Can I use these pickups interchangeably on different guitar types?

No. The T System is engineered for electric Telecaster guitars with bridge and neck positions. The ACS Bajo Oro is a soundhole pickup for acoustic guitars only. Using either on the wrong instrument type will not work.

Which has better noise performance for studio recording?

The T System delivers a -101dB noise floor at 60Hz, making it superior for studio sessions on electric guitar. The ACS is optimized for acoustic amplification and focuses on transparency rather than ultra-low noise specifications.

How easy are these to install if I've never done it before?

The T System uses solderless connectors, making it beginner-friendly—no soldering iron needed. The ACS Bajo Oro is even simpler: it drops into the soundhole with an included endpin jack and batteries, requiring zero tools or technical skill.

What's the battery life difference between them?

The ACS Bajo Oro achieves exceptional battery life on a 6V supply drawing only 220 microamps. The T System runs on 9V (or up to 27V) but does not specify microamp draw; it claims 1500 hours at standard 9V operation.
