This is one of the earlier Quantums with no truss rod. It is in very good condition, with a few nicks and scuffs along the bass side of the neck (where you can't feel them while playing). The body is in excellent shape. The pickups have coil tap switches allowing for either single or dual coil operation.
 
Price is $1900 shipping included to ContUS.

I have a Q6 from 1990 and now a Q6 TBX from 1991 and I think that Modulus was making some of their finest necks during this time. They had a much flatter profile on the back which makes it easier for people like me with small hands to get around.
 
Somebody snap this up!

That's a great deal and what a top!
 
I've had a 1990 Modulus Q6 with no truss rod as one of my main basses for 15 years. Action is perfect, neck rock solid. Haven't had a set-up since I bought it.

Going on eBay soon...
