The Marshall VS100R is one of the Marshall Valvestate range of guitar amplifiers. It is a combo amplifier doing away with the need for a separate head and speaker cabinet and combining the two. Along with the head and 2 x 12ins speaker models in the range, it is the first amplifier in its price range to offer three footswitchable channels. Essentially a 100 Watt output amplifier, it takes in 150 Watts (230V - 50hz). The amp has a rugged construction from plywood and is covered in a strong synthetic leather covering. The amplifier features an ECC83 [12AX7] valve in the pre-amp. This provides a classic Marshall tone on all three channels. There are three separate channels to the amplifier, and, as stated above it is the first amplifier to provide this in its price range. These channels include Clean, Overdrive 1 and Overdrive 2, and there are indicator LED's for each channel when in use. There is a separate equaliser for the clean channel and one that provides for both of the overdrive channels. These E.Q.'s comprise of three dials each. These are bass, middle and treble. On the clean channel there is also a "Tone Shift" switch which allows for even more sonic variety. Overdrive 1 has two dials one for Gain and the other for Volume. These dials are duplicated for Overdrive 2 that has the addition of having a Contour dial which is essentially a method of shifting the mid-range frequencies in the guitar's tone. This is an ideal amp for early gigging. With 100W of amp behind you, you can quite c comfortably perform in pubs and small clubs. There External speaker jack's in the back for additional speaker cabinets (also in the Valvestate range) and an "Effects Loop" that provides an ideal send and return system for effects units. In conjunction with the "Effects Loop", there is an "Effects Mix" dial situated with the Reverb dials. This enables the user to determine how much of th
e used effects are introduced to the current amplifier sound. It has a headphone socket in the back (which mutes the internal speaker) for silent practice as well as a "Power Dimension" switch that maintains tonal clarity at low volume levels. In addition to each channels E.Q. system, there are two reverb dials that affect (a) the Clean channel and (b) both of the overdrive channels. For recording purposes and the like, there is an "Emulated Line Out" jack socket that emulates speakers in order for as a high a recording/process as possible. There is a dual switch footswitch that is plugged into a jack socket in the back of the amplifier as well. This has a rugged steel construction that simply enables switching between (a) the clean and the overdrive channels and (b) which overdrive channel is being used/will be used. This amp is a relatively cheap one and provides excellent value for money. It also holds its value well for secondhand resale and comes with Marshall's 3 Year Warranty.
