結他維修日誌 #405 「James May Engineering Ultra Tonic 拾音器」

.

貼片拾音器（SBT）係木結他手嘅熱門選擇，因為佢可以產生自然嘅音色同埋收到打板嘅聲音。不過貼片拾音器有兩個主要缺點。首先，佢容易強調中音同結他本身嘅共嗚，提供溫暖飽滿嘅音色。但係喺音量大嘅舞台上表演時，好易出現迴響（Feedback）問題。其次，結他本身嘅結構對貼片拾音器有相當大嘅影響，令同一個拾音器喺唔同結他上聽落會有非常唔同嘅聲音。

為咗解決呢啲問題，James May Engineering推出咗Ultra Tonic，一個被動式拾音器。拾音器內置感應器用嚟消除迴響，而唔會太過減弱中頻。呢個拾音器仲有一個電路板，上面有12個開關，用家可以喺彈奏結他嘅同時將結他連接到音響設備，調整開關嚟嘗試唔同嘅迴響消除程度。呢個靈活性可以令用家根據唔同嘅結他調節拾音器嘅音色。

下一個post會繼續介紹安裝Ultra Tonic拾音器嘅過程，唔好錯過喇～

Guitar Repair Diary #405 "James May Engineering Ultra Tonic Pickup”

.

The Soundboard Transducer (SBT) pickup is a popular choice among acoustic guitarists, due to its ability to produce a natural tone and capture percussive playing. However, SBT pickups have two main drawbacks. Firstly, they tend to emphasise the midrange and the inherent "woody" tone of the guitar, which can be advantageous for warm and full sound but may result in feedback issues on loud stages. Secondly, the characteristics of the guitar itself have a significant influence on SBT pickups, making the same pickup sound different on different guitars.

To address these issues, James May Engineering has developed the Ultra Tonic, a passive pickup that incorporates an internal sensor to cancel feedback without excessively attenuating the midrange. The pickup also features a circuit board with 12 switches, allowing users to experiment with different levels of feedback cancellation by tuning the switches while playing the guitar and connecting it to an audio device. This versatility enables users to adjust the pickup's sound to suit different guitars.

Stay tuned for the next post, which will provide details on the installation process of the Ultra Tonic pickup.
