The DSL100H Kit includes the DSL100H head and the MX212 cab. The all-tube, two channel monster has the same tube compliment and feature set as the conic DSL100 with a few upgrades. You'll find a Resonance control as opposed to the original's fixed Deep switch, this gives you total control of exactly how much low-end "girth" you want to add. It features studio quality digital reverb instead of spring reverb. The rear panel Pentode/Triode switch drops it down to 50W so it's super flexible. Finally, a supplied two-way footswitch allows for channel switching and Reverb on/off. The other piece of this kit is the MX212 which is ideal for the new DSL range. The MX212 was designed from the ground up and features two Celestion speakers, MDF construction and that classic Marshall logo.
