Ashworth
A few different bridges are available:
- AJ411
A prototype was fitted to the Starfish solid violin belonging to Duncan Chisholm of Wolfstone. It became a great success. Type numbered AJ411 is the transducer bridge and is now available direct from Ashworth. 5 string variants and cello models are also in production.
- AJ11
The AJ11 has a tailored response to suit violins, mandolings and other small-bodied instruments, so that certain unwanted low and very high frequencies are smoothly rolled-off, leaving the proper audio range of the instrument clear, and less subject to finger-noise and unpleasant overtones.
- AJ111
This transducer uses a differential principle for high volume without feedback, and will not work as a "stick-on" bug. Mechanically the AJ111 acts like a loosely coupled third foot which has so little effect on the violin's acoustic properties that it may normally be left in place permanently.
Ashworth has been established in 1976 by Alun Jones, the creator of the Ashbory (TM) Bass. Ashworth acoustic pick-ups cover a wide range of instruments, but each type was developed with natural sound reproduction as a priority. The company intends to keep its pick-up prices low despite their quality.
