For Lawrence being such a small town, it's awesome that it has its own drum/percussion shop (though they also do sell some guitars here as well).
The shop features Treehouse drum kits, made locally in Kansas. Supersonic also carries a variety of percussive instruments, cymbals, heads, hardware, and sticks.
Every month, the store has some deal going on, so it's always good to call ahead of time and see what they have for sale. They had a sale on hand drums one time, and I got some nice CP bongos made in India along with a burlap tote and adjuster tool for around $20, when they were originally over $60. Supersonic also has some good quality hardware in their used pile that I have purchased on several occasions, for a fraction of their original prices--Pearl cymbal mute for $10, Gibraltar tom mount clamp for $20, normally $40, as well as an LP short bongo stand for about $30 (these can be pricey).
Even larger cities as you move eastward into Johnson County don't have a drum/percussion store! Granted, Supersonic doesn't carry the amount of inventory (I was looking for a wrap-around foot shaker and foot tambourine at one point, and no luck) that a place like Explorers Percussion in Kansas City would, but for the size of the store, this gem does a pretty decent job. One night, I was needing a filtered China crash for my kit that they unfortunately didn't carry. To my surprise, the employee took down my info and assured me they'd call when one turned up in their inventory. Thumbs up for helping the customer out!
Some of their brand-new items may cost slightly higher than what you may find elsewhere (read: online), but just do your homework and you might be able to negotiate on the used items.
Being a drummer/percussionist, this is hands down my favorite store in Lawrence. read more
