Bass of the Week: CallowHill Guitars MDM

This week we check out the CallowHill Guitars’ flagship bass, the MDM. The MDM was born out of three separate instrument models, and eventually evolved into a single model with several options.

The MDM is offered in 5- and 6-string versions with standard features including lightweight swamp ash bodies, Nordstrand pickups and a fully passive wiring stage with a modified Aguilar OBP-3 preamp.

Its passive stage is hardwired with solid silver teflon coated wiring for “optimum, uncolored transfer of tone from the pickups to the amplifier.”

The MDM’s neck features three piece construction with old growth maple and center strips of wenge.

Each bass is made to order at the CallowHill shop in Philadelphia, Pennsylvania. As such, many options are available.
