The VH100R features twin footswitchable channels each with its own footswitchable gain, independent 3 band EQ, independent reverb level and dedicated FX loop, giving you an unprecedented level of flexibility. You can now go from a super clean shimmer, to a warm clean crunch, to a stack style distortion to a full on lead tone as simply as stepping on a switch - which is included with the amp (FS4).The by word for the VH100R is flexibility - flexibility of tone and flexibility of use. In this day and age the modern guitar player has an arsenal of products available to them - from single stomp box effects to mighty racks. To cater for this level of choice the VH100R is fitted with five premium ECC83 preamp tubes and four premium EL84 output tubes. If EL84"s are not your power tube of choice one can easily switch them with 5881/6L6"s with Laneys Switchable Valve Bias. The tonal possibilities are seemingly endless. Plug into one of these with any guitar you have and be amazed at the clarity and level of gain you now have at your control. Laney - Power To The Music.
