I recently bought a Yamaha Stage Custom Bebop kit with the 15 x 18 bass - Sounds kinda flat with the stock heads - any ideas on a head combo for a deeper more open sound ? Prefer soild resonant head
I'm thinking part of your problem are the birch shells those drums are made from. Birch can tend to sound a bit
plain to begin with, but that aside, my suggestion would be to try a Remo Fiberskyn 3 head on the batter side.
I love them. They really warm up and fatten a bass drum, I think.
If you're not doing it already, give it a try.
...also, if your front head has a hole in it, seal up the hole or get a non-vented head for the front.
Lastly, if you're playing Rock with that kit, try lifting the bass drum. On an 18, leaving it on the floor, you're hittin far enough off of center that you're getting that thinner (but more lively!) sound.
Think of it, this way...let's say you're pedal is setup to hit center on a 22" bass. That puts the beater at 11" off the ground.
On an 18, center is only 9" off the ground, so you're already hitting 2" off-center. If your beater is set to hit a little high of center on the 22, now you're even farther away on the 18.
Most lifts raise the BD 2". So putting a 2" lift under an 18, raises that center from 9" to 11". Same spot as on the 22.
So, give those a try and see what you think.
