Continuing their storied tradition of building high-quality tube amps by hand in Petaluma, CA, MESA/Boogie has introduced three new designs to their celebrated California Tweed Series.
Adding to the existing ‘50s Fender tweed-inspired 6V6 4:40 1x12 Combo and Head models comes the more compact 6V6 2:20 1x12 Combo, 1x10 Combo, and Head guitar amps.
Featuring a single channel with Low and Normal inputs, the amps have been designed with an immediately familiar front panel layout that includes Gain, Treble, Mid, Bass, Presence, and Master controls.
Dual 6V6 power valves offer “smooth highs and natural tube compression” while three power levels of 20W, 10W and 1W – selectable via the Multi-Watt switch positioned on the far right of the front panel – allow for more headroom when required, along with sag and breakup at lower volumes.
Utilising patented technologies, this flexible power amp section provides two operating classes and three wiring configuration options, as follows:
- 20 Watts - 2x 6V6 Class A/B Pentode – Fixed Bias
- 10 Watts - 2x 6V6 Class A/B Triode – Fixed Bias
- 1 Watt - 1x 6V6 Pentode, Single-Ended Class A – Cathode Bias
The preamp section comprises one 12AT7 and five 12AX7 tubes, while silicon diodes have been employed for rectification.
Send and Return jacks for the amps’ fully buffered, tube-driven effects loops are located on the rear panel along with a footswitch jack for remote switching of the all-tube spring reverb (an adjacent knob adjusts reverb amount).
While the combos come fitted with a custom-designed Jensen Blackbird Alnico 40-watt speaker (either a single 10- or 12-inch, depending on the model), all three amps feature a single 8 ohm and two 4 ohm speaker output jacks for added flexibility.
