This is the Marshall JCM2000 Dual Super Lead 100 that I use in my band. It has Classic Gain and Ultra Gain channels, with 2 modes each that can take you from warm, clean tube tones to major distortion. A Deep switch adds a bass boost for a fat bottom and a Tone Shift to scoop out the mids for a huge metal sound. Each channel has its own reverb control but both channels share a single EQ. 100W of power is too much for most venues and although I love mine I?d recommend the DSL 50 for everything but the very largest outdoor venues. It uses 4 ECC83 preamp tubes and 4 EL34 power amp tubes for 100 watts where the DSL 50 uses 2 EL34 Power Tubes for 50 watts of more manageable power. This amp really sounds great and can be used either with the included footswitch for two channel operation or on the clean channel only with stomp boxes for distortion with great results. There is also an effects loop on the back and it can run 4-8 or 16 ohm cabs. Most versatile amp I have ever owned.
