The Kasha Rockmod Brick is a compact, all-tube guitar preamp designed to deliver powerful tone, gain, and sustain. Modeled after the classic Rockmod I preamp, the Brick features two channels—lead and clean—powered by four 12AX7 tubes. It offers dual master controls for the lead channel and a shared EQ for both channels. Available in standard 5W or optional 10W configurations, the Brick provides versatility and portability for guitarists seeking high-quality tube-driven sound.
