The Select-o-drive is a revolutionary new hybrid tube/solid state amplifier. The amp uses five 12AX7 premium tubes and a unique MOSFET solid state output section. This combination provides the ultimate in tonal options, responsiveness and dramatically increased reliability.


The all-tube preamp provides three distinct channels that enable the player to achieve any sound ranging from pristine classic clean to searing massive overdrive. In each setting, the touch-sensitivity and responsiveness to pick attack make the Select-o-drive a highly musical tool.


The Select-o-drive’s MOSFET output section does not use global negative feedback. The result is an open, natural sound that feels like an amp using power tubes, yet does not require a heavy output transformer.  In addition, the output section features the Alairex proprietary Variable Soft Clip Control (VSCC).


This unique patent-pending circuit gives the amp a completely variable output section that determines the point at which soft-natural clipping occurs within the full power range of 2 to 80 Watts RMS.
