DESC: A practice bass amp with big-time tone. Most practice amps sound like practice amps. The Peavey MAX 158 is an exception. Thanks to TransTube emulation circuitry, it has sweet tone that makes practicing or warming-up backstage a pleasure. A voicing switch gives you modern or vintage drive. 3-band EQ. 15W power. 8" bass driver. Tape/CD in. Headphone out.
