The KatCab U1 External Speaker Mod will allow your combo amp to have a Speaker Out (if it does not have one) to use an external speaker cabinet.

Will work with Peavey, Line6, Marshall, Fender, Blackstar, Ampeg, Carvin, Vox, Mesa Boogie, Sunn, Egnater, Behringer, Gibson, Kustom, Laney, Supro, Crate and many other combo amps.

KatCab U1 options:
  1. Internal speaker
  2. External speaker

Always match the speaker impedance of your internal speaker. Total Ohms for all connected external speakers must be the same as the internal speaker. Check manufacturer technical specs.
