I am looking to the replace the Ghost piezo monorails and preamp on my Washburn AB40 Stu Hamm model. They sound okay, but it's a noisy system with low output. I was thinking that Ibanez monorails & preamp might work. The bass is semi-hollow, so my first choice (K&K Pure Sound) won't work -- the block under the bridge is in the way. I hate to toss in the towel on this instrument, so I'd welcome your suggestions. I'll have to find someone to do the work, as this is not my line. Thanks for any help you might be able to offer.
