Quantum Bass Center's handmade C extensions
- Top-quality parts and workmanship
- Genuine ebony extension body
- Crack-resistant, highly durable, self-lubricating composite gates (levers)
- Extremely precise intonation
- Adjustable if you change your bridge placement
- Elegant and extremely strong while minimizing excess bulk and weight
- Hand-fitted to your scroll: no pads, filler, gaps, or cutting of the scroll; see photos for widely varying scroll projections to which we have fitted extensions that play with no more than 4mm fingerboard clearance at the E gate!!
- Straight string pull both down the fingerboard and through the scroll to the tuning peg
- Only one small hole through the scroll - the side of the scroll is never cut
- For lowest tuning friction and minimal weight, our default is to pass the string through the scroll without the use of additional pulleys.
- Accurate string spacing and minimal fingerboard scoop so you can close the E gate with one hand
- We have built perfectly-functioning extensions WITH a false nut, and also on a 5-string bass
- QBC is the trusted constructor of top-notch C extensions to numerous nationwide professionals
- Call or email to get on the appointment list today! Average construction time: 2 weeks
