Interestingly, I'm a User Interface / Experience Designer and I have the opposite opinion, tau!
The seemingly industry-standard approach to bass knobs - i.e. unlabelled with no numbers, lines/gradations, and often no pointers - has frustrated the hell out of me for decades.
That Pbass-originated piss-poor UI has inexplicably become the norm - even on instruments of expense with complex electronics.
I recently bought a Dingwall. £2500, and 5 blank unlabelled knobs. Want to know what the knobs control or what they're set at? Have a twiddle and see if you can figure it out - it's the only way to know. Good luck!* 🤷♂️
It's doubly frustrating when you consider that Leo himself got it almost perfect first time with the Stratocaster's knobs. We've gone backwards through laziness, naivety and misguided aesthetics.
Having owned a Wal myself, I can say with certainty that they are still my benchmark rotary control. Ian and Pete knew what they were doing. Admittedly, they're not the best looking, but boy, they are a delight to use. Great work, @remizik !
* And don't get me started on unlabelled Active/Passive or Series/Parallel switches!
