Overview - Mesa/Boogie Three Channel Dual & Triple Rectifier Solo Heads Owner's Manual

Dual & Triple Rectifier Solo Heads

Overview:

Congratulations on your choice of the new Three Channel Dual or Triple Rectifier Solo Heads as your amplifier!
Their two channel relatives launched a sound back in 1990 that would come to define a musical style and now, a decade later, are
synonymous with high gain guitar. The "Recto" - as it is affectionately known - has found its place in history as a rock 'n roll icon and
seems to be growing in popularity every week. The long and ever growing list of recording credits and inspired owners endorsing the
beyond gain performance of these all tube machines of mayhem is testimony to their tone, versatility and reliability. The time proven
magic created by combining our patented Switchable Dual Rectifier power section with two different tube preamps of unsurpassed
gain, focus and expression created an instrument of devastating power.
Well that combination just got exponentially more powerful with the release of the Three Channel Dual & Triple Rectifiers. Now
there are virtually no limits or compromises as you can footswitch between three discreet channels - each sound dedicated and fully
evolved! An entirely new channel dedicated to rhythm sounds lets you choose between two modes...CLEAN with its many colors of
normal gain staging - and a boosted, re-voiced PUSHED circuit that reveals an urgent, more aggressive gain range that is perfect for
crunch rhythm or medium gain soloing.
The two LEAD Channels have also received a comprehensive revamping that retains the original two essential Recto modes VINTAGE
& MODERN in all their blistering glory, but also adds an amazing new mode dubbed RAW. That's right, three modes per channel! The
RAW modes' super sensitive personality roams effortlessly through virtually all ranges of gain...from almost-clean to a fast tracking
crunch, allowing you to harness the Recto spirit for any style of music. With these two new lead channels you may footswitch between
any two of six solo modes! And if this performance minded power isn't enough to get you through a gig, we have fitted the new Recto
with the SOLO Control found on some of our other models. This valuable feature is an additional volume control wired in parallel to the
OUTPUT Control allowing you to footswitch to a preset amount of volume boost during live performance. And finally, to top it off the
EFFECTS LOOP has also been updated to include a footswitchable option to the already complete array of programmable choices.
These eight modes housed in three new simple to use channels, along with the other improvements, open new doors for the Recto to
be considered by any player wanting great clean sounds and a myriad of solo possibilities. While they still remain the hardest grinding
heads out there, this new versatility is sure to land the Three Channel Recto in some surprising new musical environments.
