This is an exceptional DSL modded by Trace of VooDoo Amps. Has Bottom and Cream mods on the back. Amp is in great shape and working perfectly. This head provides all the extra gain you'll ever need. Features Classic Gain and Ultra Gain channels, both with 2 modes that can take you from warm, clean tube tones to the souped-up threshold of sonic danger. A Deep switch adds a resonant bass boost for a meatier bottom end and a Tone Shift scoops out the mid frequencies making it ideal for heavy metal tones. Reverb controls for each channel let you adjust the 'verb where you need it. Rear panel features include the usual speaker outputs, effects loop, and 2 footswitch jacks for changing channels and switching reverb in and out (footswitch not included). Delivers 100W of power and includes 4 ECC83 preamp tubes and 4 EL34 power amp tubes.
