The Monarch Reverb Plus is just like the Monarch Reverb except.weve given it the full Chimera tone stack instead of the voice switch (basically makng the switch variable) AND we have incorporated into the design a novel tube driven power scaling circuit powered by a 6L6 power tube (set up like a voltage regulator). This approach allows plate resistance to still exist in the power supply (despite the lack of a tube rectifier) which leads to sag and harmonic richness at any volume. The maximum wattage setting (15 watts) bypasses the 6L6 in order to create an option for pure solid state rectification if desired. The power ranges from 1/2 a watt to 15 watts making this an incredibly versatile amplifier for studio or stage!
