A genius (not) fitted my mandolin (a Kentucky flatiron) with a pair of stickons - belcats I think - one under each foot of the bridge. Since the top is both thick and small, the output from the piezos is very low. And because there is no preamp inside, it is a difficult signal for many mixers and DI boxes. Most DI boxes seem to ahve an input impedance of only about 250k. The Baggs paracoustic has an input impedance of 10 meg (more like it) but I also need a large gain. I would also like something cheaper than the paracoustic. Suggestions? |

The Fishman has volume, bass and treble controls and the PUTW just a volume control. Despite this I tend to use the PUTW more often both with PUTW and piezo pickups as it sounds more transparent to me. The gain is similar for both. The PUTW goes in the endpin jack (if there is one) while the Fishman clips onto your belt. Peace moo |

As far as I have been able to find Fishman do not publish technical details like the input impedance of their belt preamps, does anyone know better? I don't remember any details of the input impedance of the PUTW one being on their website last I looked, but I will check. Maybe I just keep on with a little DI box, albeit it gives me no volume control (or carry a huge great old valve box mixer that at least has a huge input impedance - about a megohm or so...) |
