What skill level do I need to install this?

Installation is intermediate to advanced; the circuit ships pre-wired and ready for integration, but you'll need familiarity with guitar wiring and electronics to route it into your instrument properly. If you're comfortable rewiring pickups or working with active circuits, this is a straightforward swap.

Can I use this with passive pickups?

Yes, the STC-2S-BO is compatible with both active and passive pickups, so you have flexibility in your pickup choice while using this tone circuit.

What makes this different from a standard passive tone control?

Active EQ eliminates phase shift and artifacts that passive controls introduce, delivering surgical precision with zero signal coloration or noise. The separate bass and treble pots with switchable treble frequency centers let you dial in exact tonal adjustments without the sonic trade-offs of passive circuits.

What's included in the box?

The harness comes pre-wired with individual bass and treble potentiometers, a battery clip for powering the circuit, a stereo jack, and black anodized knurled dome-style control knobs ready for installation.

Is this suitable for live performance and studio recording?

Yes; the high headroom and low-noise design make it equally effective for both studio sessions and live performance, maintaining clarity and signal integrity across any playing context.
