Need some advice. I have an Aria IGB68/5 lefty but the bridge is clearly designed for righty as the lefty B & E strings can't be adjusted back any further so intonation is out markedly. If I played righty strung lefty no probs but the cavity under the bridge makes a normal bridge unusable as their mounting screws are over the cavity, into space. I've searched & the only bridge that seems a work around is the G&L as it has side mounting screws. Any other suggestions or ideas welcome. Thnx
