here are the things that you would need to convert your floor tom into a bass drum:
PEARL JG-16 JUNGLE SET ADAPTER
ISS or optimount:
Outcome:
when you buy the JG16 adapter, you should also buy either a Pearl ISS (for 16 inch toms) or Pearl Optimount (varies in depth so measure the depth of your floor tom, not the diameter!). Either ISS or optimount will work with the JG16. Optimounts are just the new mounting system of pearl. If you're more adventurous you can buy tom mounting brackets and install them on one side of your tom to accommodate the jungle adapter.
Alternatively, if you are in a budget, you can go to Lazer because they also have an alternative to the pearl accessories mentioned above for this project. Not more than 1k pesos if im not mistaken.
If you want the bling of all trades, DW offers 9909 Bass Drum/Percussion Lifter as an alternative:
have a good one! post some pics as soon as you're done.
