You’d know better than me, but I suspect that there are more than a few guitar shop guys with a rudimentary command of English in HK. But I wouldn’t be talking to salesmen right away. First thing I’d be doing is hooking up with local players and trying out their axes. I’d imagine there are expat Brits and Aussies who rock on the weekends, not to mention Chinese guys who are into the East Asian (mainly Japanese) metal scene in all its bodacious glory.
You mentioned effects pedals. Chances are, if you’re using effects pedals, you’ll be playing a solidbody electric. Effects pedals are usually used when music is played at high volumes, in rock and blues. Hollowbody guitars will tend to feedback at high volumes, so they’re a lot less common in rock. Hollowbodies are common in jazz, where a cleaner, mellower sound is called for, with a lot less distortion and effects. (Think George Benson or Wes Montgomery)
Soldibody electrics have traditionally been grouped into two main categories, the Les Paul style and the Fender Strat (and Telecaster) style. Les Pauls typically have a wider neck that is more comfortable to play, but also more difficult to reach for tricky string combinations.
Les Pauls usually have two humbucking pickups - each rectangular metal pickup cover has two single coil pickups underneath it, positioned side by side. This arrangement cancels out some of the hum and noise that comes through with single coil pickups standing alone. Humbuckers also cut out some of the high tones, and increase the strength of the signal, giving a fatter tone with less brightness than you find with Fender Strats. Jimmy Page was a great Les Paul player during his Led Zep days. The maple top LP’s that Page and other rockers favored also had more sustain and heavier weight than Fender style guitars.
Fender Strats have three single coil pickups, with a selection switch that allows you to combine the pickups for tonal variety. Single coil pickups capture more noise but also more high tones for a brighter, sharper tone. The narrower neck on a Fender is less comfortable to play, but allows for better reach for different string combinations.
Fender Teles - the model immediately preceding the Strat in development by the Fender company - have two pickups, a sharper,brighter sound, and markedly less sustain than Les Pauls. Teles have long been a favorite of country and western quick picking guitar players, though Keith Richards and other blues influenced rockers have also preferred Teles. Strats, by contrast, have been the axes of choice for guitar gods like Hendrix and Clapton.
Nowdays there are all kinds of imitations and combinations of the Fender and Les Paul styles, mass produced in Asia, custom made in Europe and the States. If you’re looking for rock bottom cheap that still gives you an acceptable sound, try the Yamaha Yamaha EG-112, a Strat copy with one humbucker and two single coils. OTOH, if you’re a serious player ( you give that impression) talk to a lot of people and try out their instruments. You can sometimes find a used classic six string with a beautiful sound for a few hundred.
