Haha glad you thought of me.
Singapore has a great amount of Gibson and Fender guitars. PRS not so much but let me share.
Swee Lee: Major retailer. Official for G and F. Multiple outlets . Biggest selection is in the Bras Basah outlet near the City Hall train station. Nicest shop is in Star Vista mall (right next to my office) where they have a nice cafe and a well used deals section where you get brand new NOS guitars at crazy prices
https://www.sweelee.com.sg/
Peninsula shopping centre and Excelsior are adjoining malls near City Hall as well that contains a lot of guitar stores
Davis Guitar: Official PRS retailer. Not the largest collection though
https://www.davisguitar.com/
Maestro Guitar: Boutique Singaporean acoustic guitar maker
https://www.maestroguitars.com/
And many others, whose names i dont recall but occasionally you see good second hand instruments
Located in Dhoby Ghat, one train stop away from City Hall are
Yamaha music in Plaza Singapura mall for Yamaha products
City Music in Peace Centre mainly for Martin and some other brands
Also check out the online market place Carousell.sg for lots of used deals . Singapore is a low crime country so theres a very low chance of getting scammed and all the listings are genuine
Last but not least, shameless plug. I have over 30 guitars including 10 or 11 core PRSs (i lost count
) and some relatively rare guitars picked up from Japan. Since I have a PS on order, I have a few of them listed for sale at
https://sg.carousell.com/utkarshmohanguitar but there are others hiding ( i only really have 2 guitars I will never sell, my first epi lp and the 594 my wife gifted me). So drop by
