Re: [Simmons Drums] Noise from Headphones

Hi!

I guess that they wanted stuff you'd gig with, not practice with at home. 
The SDS-2 has a separate headphones amplifier which is from another planet 
or something. With a pair of modern headphones plugged in you can call your 
ear doctor on the double 'cause that thing is mental and dangerous.

electronically yours, jesper - tried it once - *aouch*
