The Marshall Vintage Modern 2466 Tube Amp Head is an all-valve amplifier with a choice of two dynamic ranges selectable by footswitch. The Low range equates equates to the performance you would come to expect from a stock vintage Marshall amplifier in terms of tone and available gain. The High range adds an extra preamp valve into the signal path, facilitating those classic hard rock tones of the seventies. Add to this the ability to dynamically interface with your instrument's Volume and Tone controls and the experience translates into a truly expressive and organic feel in performance.Two frequency selective Pre-amp Volumes (Gains) - Body and Detail - facilitate greater flexibility in tone shaping for individual guitars and styles while the power amplifier is heavily influenced by the first Marshall amplifiers to be produced, with four KT66 output valves yielding that substantial, fat and smooth tone. A MID Boost switch on the front panel fattens the tone even more while a traditional Marshall tone control circuit enables fine tuning of your sound.A master volume has been included in order to practically manage the output levels at all venues. This is implemented after the phase splitter in order to fully exploit maximum preamp drive when the master is turned down low. A reverb level control mixes the on board plate reverb with the direct signal to whatever degree the player chooses. The reverb can be toggled on and off via the footswitch.Finally, a series FX loop is provided for those players who wish to use outboard effects to further enhance their sound. Loop levels of 10dB and +4dB can be controlled via a rear panel switch as well as the option to completely bypass this feature if it is not required.The cosmetics are also a carefully crafted hybrid of old and new styles made even more dramatic by the deep purple vinyl that covers the entire series.
