Review using: Esprit guitar, all mahogany chambered body, set neck rosewood fretboard, dual duncan designed humbuckers.
Originally i put a metal-s for both pickups and the result was clear overall sound, balanced lows and emphasized upper mids. When i split the coils, I noticed that they sounded like P-90s. Then i tried the classic crystal-s, same overall effect but less mids. Then put a crystal-s on the neck pickup and metal-s on the bridge. Great results-bell like tones in the neck and hot punchy in the bridge position.
Later veg-joe suggested connecting the two types in parallel affecting both pickups. So i did it and thats how the soon to be released duo-core scalarizers was conceptualized. Its like listening to two gutars in unison but distinctly yet in harmony. gulo ba? Basta ganun.
To fully appreciate having two types of scalarizers in a guitar, its best that you hear them function individually, to entune your ears to the character of each. Some would be happy with just the crystal-s or metal-s. Depends in your taste, type of music, type of guitar etc. The great thing is there is a scalarizer suited for you. Now there is even an acoustic version pa!
Another way to look at the effect of the scalarizer:
Its like using an equalizer to smoothen edges, increase frequencies that lack and remove annoying frequencies. In short, whatever you dont like about the tone of your guitar, it will fix. No need for an equalizer.
Save time and money on experimenting which pickup and hardware combination etc etc to install cause its just a never-ending quest. Imo, no pickup will ever be perfect for you. This device will help you reach the ultimate tone.
Its like a mic inside ur guitar that pickups the wood vibration hence the 'woody' effect. Unlike magnetic pickups that pickup the strings vibration (of course he vibration of the strings is also wood dependent. You 'hear' the wood and the strings at the same time hence the 3D effect and longer sustain.
In my tele:
Like Nathan, I also thought my tele was clear and punchy enough but I put in a crystal-s anyway. Result - Lalo pang luminaw but sans the high peaks. Now i dont need to rolldown the tone knob ever so often. Mas nagkapunch pa. Mas dinig ko yung wood tone ngayon.
