I have an a600 can anybody here explain to me how i go about disabling the internal low pass filter?
Disabling Amiga Internal Filter

That depends on what software you are using. There is no native Amiga shell command to switch the filter on/off, but such commands can most likely be found on AmiNET.
In Protracker it is the E00/E01 effects.
If you need a hardware solution you might find some help here: http://eab.abime.net...ead.php?t=57073 ?

Thanks for the reply,yeah i have been on that site an awful lot and cant get my head round it.I use gvp soundstudio as it came with my dss8+ The dss8+ has an option when sampling to turn on or off the anti aliasing filter,im not sure if this is the internal amiga one or if it is the samplers own filter.I have heard people say the the a600 sounds much duller compared to the a1200 as well do you think there is any truth to this?

This isn't probably going to help you, but I had Amiga back in the day *dreamsigh* and have a vague memory of a short program I got somewhere that you could execute in shell and turn off the filter. So yeah, AmiNet is probably a good place to start. It was pretty easy to do in Assembler, but I don't remember how anymore.

If you want to do it in assembler, it is easy. Set the bit number 1 in $BFE001 register to get the led off and filter off - bright sound. Clear the bit to get opposite - led on and filter on - filtered sound.
BSET.B #1,$bfe001 RTS
BCLR.B #1,$bfe001 RTS
Drop it to assembler, assemble, save executable in command directory and you got DOS commands switching leds on and off.
Alternatively use this Amiga executables in zip pack, what I made some time ago:
