Compatt/A™ Input Buffer

The Compatt/A™ is a discrete Class-A input buffer for guitar. It will safeguard, strengthen, and prepare a guitar's signal for whatever follows on a pedalboard and in a rig.

The Compatt/A™ is a discrete Class-A input buffer for your guitar. It will safeguard, strengthen, and prepare a guitar's signal for whatever follows on a pedalboard and in a rig.

The discrete Class-A circuit has an input impedance and other finely tuned characteristics which mimic that of tube amplifier inputs.

It presents a guitar with a dynamic and ideal load that remains steadfast — resulting in consistent tone while still allowing the guitar to breathe and feel, as if it were plugged directly into the front of a beloved tube amp.
