Acid techno tune id's

[DarkYoung]

Hi there not getting any luck in the other forum so thought i'd move it over here. These tunes are not rare i've heard them loads of places just dont know the names myself. Your assistance in helping me track these buggers down would be greatly appreciated

thanks

i think the first one is a wah wah one?

the second one is something by geezer, i think it's either on wah wah or raw (sounds very raw to me).

third one again sounds like something from raw.

the fourth one is one of those tunes off a label i cant think of at the moment.
it'll come to me.
