I know there has been a lot of people bashing the spector tone pump, but thats not what this thread is about... I'm buying a second hand Spector EuroLX 5 and the preamp seems slightly different, or maybe spector has made changes to the tone pump? it doesn't have the 2 volume pots, but instead has a single volume and a balance pot? the tone pump pre is supposed to be boost only, does it have center detents, as this one seems to have center notches (which indicates it might be able to boost and cut?) anyone know if this is the original pre?
