Inspired by classic tube bass amps but with modern features and performance, the Ashdown CTM-100 tube bass amp head is built to perform night after night. It's got the tonal range to cover everything from smooth, warm and clean (with mellow push-button engaged), to overdriven and growling with the gain cranked. You'll get plenty of punch, power, and headroom for small-to-medium size gigs from the CTM-100's power section, which packs two 6550 power tubes. In addition to standard tone controls, you can fine-tune your perfect tone with Deep, Mid Shift, and Bright switches. For a solid tonal foundation for your bass rig, it's hard to beat the rugged Ashdown CTM-100 tube bass amp.
