I've always wondered why they never revised the controls for the El Tuekay. I mean, it's not like it's unprecedented-- Music Man revised the controls of their iconic Stingray on multiple iterations.
And before anyone mentions it, yes, I'm already aware of the "M" series basses. Despite the cosmetic similarities, they are, functionally and sonically, different animals altogether (not inferior by any means, but definitely different).
I think a useful control layout would be (4) knobs: Volume, pan, Treble, Bass; and (3) switches: Series/Parallel/Split, Pre-amp On/Off, 3-way preamp mode-- Bass Boost (think OMG 2.0), Flat, Treble Boost.
If I'm not mistaken, the OMG switch on a Wunkay is a low-pass filter (treble cut), hence why I referred to the bass boost as "OMG 2.0".
I'd also revise the pre-amp to 18V, with a quick-change pop-up battery compartment. That I can get one on a $300 Ibanez but can't on a $2K+ luthier-built instrument is one of those industry phenomena I have never been able to wrap my head around...
