1 DCBirdMan 9 months ago Mojo can make me a front panel Champ cab to hold a 10. Typical 1964-79 Champ cabs are 7 1/4 " deep. This can also be made has a shortened Music master bass cab, which is same dimensions but is 9" deep -- that's just how they designed in for a 12. Both of course are open back combos. Will that 1 3/4 " extra depth of the MM Bass cab make any difference in overall tone/depth of sound -- seems unlikely but had to ask.
