Can anyone tell me how the treble and bass knobs on a L2500 or L2000 work. Because they have no mid position detent, I'm wondering if they're not the typical cut and boost type, but maybe a shelving type where full on clockwise is normal. Is this correct? I had a look at the G&L site, also at Guitars by Leo, but could'nt find the answer there. I'm just curious. Also I've found that stringing through the bridge rather than through the body gives a better B string tone. Anyone else found this?
