[quote=elgecko;9772624]I've had my CMD121P combo for 3-4 years now. The whole time, I've been doubling between bass guitar and EUB, physically switching out instrument cables between songs. That made for some exciting changeovers (e.g. pulling on a cable and knocking over a mic stand, bird nests, etc)...the whole time, lamenting replacing my old 2-input Walter Woods with the Markbass.
It recently dawned on me that the XLR dealio on the front panel had the word "input" next to it.

One XLR-1/4" adapter later and I'm once again enjoying the benefits of a two input amp!
And to save anyone the trouble
And, the new LMT models have a separate volume control for that XLR input, and the XLR input is a combo jack, which allows for 1/4" or XLR input. In addition, the XLR input has switchable phantom power for use with a microphone for DB.
