neuro182: For Fenders, I recommend Fender Japan. It's the number 1 guitar brand in the Japanese market, because of its sheer value-for-money.
For Gibson, I recommend Greco for LP copies.
However, if you are hell bent on getting Fender/Gibson from Japan, I will have to source for shops that are near my contacts... I cannot guarantee low prices... The guitar street you mentioned could be in some ultra-urban place ie Tokyo. I must find out about it from my dad and his friends. Be warned that there are fakes out there that are passed as vintage...
Thanks for the interest.
On another note, I bought a wireless 2-mic system yesterday from Sim Lim Tower. It's not from Enzer, though. Will keep you guys informed about my mod.
