This got needlessly rambly... so the TL;DR; -- I need advice on how many knobs I can comfortably fit into a Precision control cavity. Although in many ways, I've learned my lesson in the past about modding basses, I've had a number of things lately convince me to try my hand at a particular variety of Frankenbass: been nostalgic for my first real bass; a 1978 Fender Precision. Was stolen in the early 90s I'm currently pretty much an only carbon fiber sort of dude. Mostly Modulus I'm also pretty much fully converted to preferring active pickups The bass I've been waiting to re-acquire recently (Modulus VJ) seems as rare as hen's teeth lately So, I've been haunting some graveyards and have looted the following bodyparts: Status Jazz neck (ordered... we'll see how long it takes) 93 Fender American Standard Precision body. Appears to have been some sort of second (this was bought off ebay from a seller who has a lot of these seemingly original bodies that have obviously never been assembled). If anyone knows the likely origin of these, I'd be interested Bartolini BR8CBP Precision pickups Hipshot Hardware (including detuner) OBP-3 I bought off someone here on Talkbass in 2013 or so (according the envelope its still in) I intend to run this active/passive, in case I find I don't like an Active Precision So, there are many ways I can knob this cat... but my preference would be (I think) Volume (stacked with a passive tone control, otherwise I'll have no tone control when passive) Push Pull for active Mids (400 or 800mz sweep) Low and High active control stacked edit: Just realized I forgot the active/passive switch So, assuming I don't route a side-jack for my input, three knobs would require a custom pickguard (I own a Shapeoko cnc, but to do the 45 degrees bevel, the bit is three times what a custom pickguard would be... so I'm learning towards paying someone to just do a normal guard with the knob holes ommitted). I would prefer to use barrel knobs (over minis), and although I'd not hate four knobs, I think it'd start looking odd. I don't love the busy look of the commercial stabs at Active P-basses.... So, I pretty much know what I'm looking for, but was looking for ideas and/or observations and potential bottlenecks I've overlooked. Thanks for reading.
