SPEAKERS:
These jacks handle the output to speaker cabinets or the internal combo speaker in your Express . There is one
8 Ohm and two 4 Ohm jacks here and between these outputs, most popular speaker combinations can be accommodated. You’ll
find that different impedance loads change the way your amp sounds and feels - and though it is usually best to match the load you
are using to the matching SPEAKER impedance output – you may find a certain mismatch combination to your liking. For example,
some players like the tighter, bolder correct-match-response of an 8 Ohm speaker on the 8 Ohm
SPEAKER output. Others may prefer the scoopier, more elastic vibe of the 8 Ohm speaker on
the 4 Ohm jack. Feel free to experiment as your
Express is capable of running with most any load
and producing amazing sound. If you prefer the sound of an impedance mismatch, by all means
go with the Tone.
NOTE:
Using impedance mismatches in the low direction (i.e. a 2 Ohm load on the 4 Ohm output)
will cause the power tubes to wear a bit faster.
COMBO:
Express combos use either one internal 8 Ohm speaker or, two 16 Ohm speakers (wired in parallel) to produce an 8 Ohm
load. If you wish to use an extension speaker cabinet (we make several matching Express cabinets, see you nearest dealer) you will
need to remove the combo’s speaker from the 8 Ohm SPEAKER output and connect it and the extension cabinet (also 8 Ohms) to
the two 4 Ohm jacks for a correct impedance match.
HEAD:
Express
heads can be used with most any speaker enclosure. Most MESA cabinets 1x12, 2x12 and 4x12 are wired to
8 Ohms. If you intend to use a non-MESA cabinet (we we’re sure you’ll find our cabinets superior both in sound and construction)
that is wired to 16 Ohms, connect it to the 8 Ohm SPEAKER output.
Now that we’ve covered the features and operation of your
Express
, it’s time to enjoy the best part…the sound and feel! We wish you
many years of inspiration, fulfillment and musical satisfaction from your new
Express
.
