In an earlier thread it was surmised that due to the physics of thicker resonant heads you could expect a boomier sound if you used them in conjuction with your fave batter head. The G2 over G-Plus combo is DYNOMITE on my SQ2's. The factory heads really choked the sound out (a 5K kit with shitty heads.....had Sonor spent another 25 bux, they'd have made perfection). Anyhow, changed the batters and resos and now the kit sounds like a cannon, the way it should sound. Im very thankful for those who took the time to test this hypothesis and prove it. The money spent on new heads is well worth the 'sound' returns.
