I just picked up a Yamaha BX-1 bass with a serial dating it to April 2 1987 which has one of these Hollis Research preamps inside. It's my second BX-1, I loved the first one so much that when another one came up in pristine condition just couldn't pass up the opportunity. The first one dates to April 25 1987 but doesn't have a Hollis preamp inside so I'm guessing it was installed by the owner although I could be wrong. Interesting that the original poster had one in his Yamaha bass. Couild this be something that Yamaha was offering as an optional extra from the factory maybe?
