but usually, less is more. If you can maximize your output / what you already have / what you can afford without going overboard, you'll be in a solid spot. Look for things like durability, quality, and accessibility. Below are some notes and resources for further exploration.
NOTES
Rhythm section is often the most confounding piece
Learn the function for each instrument, then teach as a unit
For equipment, maximize without going overboard
Simplify drum set
18-20in bass drum
Small rack tom (12in)
Floor tom
14 in snare drum (coated head)
Remo coated Ambassador
Hi hat cymbals (crucial!)
Ride cymbal (most important!)
Dark crash or ride with a different sound
Sticks, wire brushes, yarn mallets
Sets: Gretsch, Renown (better quality), Catalina (cheaper), DW, Yamaha
$800-3000
Cymbals: Zildjian
starts at $1000
Heavy duty stands and hardware
Sweetwater Music (good customer service)
Tune in P4s low to high (E A D G)
Bass
Amp
As neutral and natural a sound as possible
Mark Bass, GKs (combo amps [head+cabinet])
EQ is as "equal" as possible - knobs in the middle [goes for keyboard & guitar amps too]
Turn up treble to increase clarity (larger spaces)
Turn down treble for less "tinny" sound (smaller spaces)
Don't turn gain too high, don't crank master volume
Set gain at 9 o'clock then bring master up to 12 o'clock
P-Bass, Fender Jazz Bass
Guitar
Amp
Fischman, light weight options, Fender Twin Reverb
Tube amps = warmer sound but pricy-er
Hollow-body electric, Stratocaster works but have to fiddle with EQ, Semi-hollow-body is good middle ground
Keyboard/piano
Amp
Roland (cube) sturdy
88-keys, weighted
Cassio Privea, Nord Stage (price-y)
Piano sound, Rhodes sound (electric keyboard sound)
Acoustic preferably
Brass
Mutes
All
Bucket, cup, plunger
Trumpets
Harmon w/o stem
Straight
Trombone
Straight on occasion
Saxophones
mouthpieces may vary -- encourage having a separate jazz-specific mouthpiece, but this isn't always financially feasible
reeds -- there are specific jazz-style reeds, but not every student needs them
listen for the sound you want from the saxophones; if you don't hear what you want, look into different equipment
